Every October our club group chat goes quiet for about two weeks and then explodes the week of the lobster opener. Who has a spot on the Friday night charter, who still needs a report card, who can lend a gauge, whose gloves went missing last March. The opener is the one event of the year that pulls in members we haven't seen since spring, and it's also the event where a little organizing makes the biggest difference between a great night and a frustrating one.
This guide walks through how we plan a club lobster dive for the California recreational spiny lobster season: the 2026–27 dates and rules everyone needs to know before they get wet, how to pair buddy teams, what gear to put on the checklist, and how to run the night itself so everyone comes home accounted for — whether they catch a limit or just watch.
2026–27 California lobster season dates
The recreational season opens at 6:00 p.m. on the Friday before the first Wednesday in October and closes at 11:59 p.m. on the first Wednesday after March 15. For this season that means:
- Opener: Friday, October 2, 2026, at 6:00 p.m.
- Closure: Wednesday, March 17, 2027, at 11:59 p.m.
The evening opener suits a club event well. Spiny lobsters are nocturnal and leave their dens to forage after dark, so the first legal hour lines up with the best hunting. It also means the opener is a night dive for most people, which shapes almost every planning decision below.
A practical note for mixed groups on a boat: south of Point Arguello, hoop nets can't be set in the water in the 24 hours before the opener, and hoop netters are limited to five nets per person and ten per vessel. If your charter carries both divers and hoop netters, make sure everyone knows who is doing what.
The rules every club member needs before the first dive
We run a short "bug night" at the club meeting the week before the opener to go over the regulations with gauges in hand. It takes thirty minutes and it's the best insurance against someone having a bad conversation with a warden. The points below are summarized from the California Department of Fish and Wildlife (CDFW) recreational lobster page; point members there for the full text, and check it again before the season because rules can change.
License and report card
- Fishing license: anyone 16 or older needs a valid California sport fishing license. Fishing in ocean waters south of Point Arguello also requires an Ocean Enhancement Validation ($7.30 for 2026), unless you're on a one- or two-day license.
- Spiny Lobster Report Card: required for everyone taking lobster, including children under 16 who are taking part. The 2026 card costs $12.70 and covers the whole season. A member who only comes along to watch and doesn't fish doesn't need one.
- Fill it in before you get wet: the month, day, location, and gear code go on the first available line before you enter the water, and the card has to be on you while fishing. On a boat, that means in the dry box, not in the car.
- Report by April 30: cards must be returned or reported online by April 30 after the season closes, even if you caught nothing. Missing the deadline means a $21.60 non-return fee when you buy next season's card.
Size, limit, and how you take them
- Bag and possession limit: seven lobsters per person.
- Minimum size: 3¼ inches carapace length, measured in a straight line along the midline of the back from the rear edge of the eye socket to the rear edge of the body shell. Tail length doesn't count.
- Measure underwater, immediately: you must carry a measuring device, measure each lobster as soon as you catch it, and release short ones on the spot. Undersized lobsters can't go in your bag, even briefly, and can't leave the water.
- Hands only: skin and scuba divers may take lobster by hand only. No hooks, snares, spears, or tickle sticks.
- Keep them whole: lobsters must stay whole and measurable until you're preparing them to eat. No tailing on the boat or at the launch ramp.
- Know the closures: many popular reefs sit inside Marine Protected Areas where take is prohibited. Check the site against CDFW's Ocean Sport Fishing Interactive Web Map before you pick it, not after.
We recommend a dedicated lobster gauge over a tape measure. CDFW makes the same recommendation, and at night, with gloves on and a lobster pushing back, a fixed gauge is simply faster and less prone to error. Have members practice on the gauge at bug night until they can check a carapace without looking twice.
Set the experience bar for the event
A lobster dive combines two things that are each manageable on their own: a night dive and a task-loaded dive. You're reaching into ledges, holding a light, handling a gauge, and working a bag, often in surge and kelp. Buoyancy and air awareness tend to slip when someone's attention is on a pair of antennae under a rock.
For an open club event we ask for Open Water certification, at least a couple of recent local dives, and at least one prior night dive. Members who haven't dived since last season should get in the water once in daylight before the opener. It's also worth checking weighting on that dive, since plenty of people dive heavier in October than they did in July — our weighting guide is a good refresher.
First-time hunters are welcome, and we make a point of saying so. The best way to learn is to go out as the second diver on an experienced member's team, hold the light, and watch how they approach a den before trying it yourself.
Pair the buddy teams on purpose
On a lobster night the organizer should build the teams, not the parking lot. Our rules of thumb:
- Teams of two. Three-person teams separate easily at night, especially when one person stops to work a crack.
- Pair a hunter with a first-timer where you can. The experienced diver finds the lobster; the newer diver learns to spot antennae and practices measuring.
- Agree on roles before the dive. Who leads, who holds the light when the other goes in for a grab, and who calls the turn on gas. Buddies who are both head-down in the same ledge aren't watching each other.
- Agree on a hard turn pressure and a maximum time. Lobster hunting burns air faster than a sightseeing dive.
Give each team time for a proper pre-dive buddy check in the light, and add three lobster-specific items: both lights work and have backups, the gauge is clipped where it can be found by feel, and the bag is closed and within reach of either hand.
The club lobster gear checklist
Put the checklist in the event post so no one discovers on Friday afternoon that they're missing something. On top of standard scuba gear and exposure protection for water that's often in the 60s °F this time of year, each diver needs:
A primary light and a backup
Lobsters sit back in cracks and under ledges, and you're looking for antennae and eye-shine at the back of a hole. A narrow beam does this better than a wide flood: it reaches into the crevice without lighting up every particle in front of your mask. Around 1,000 to 1,500 lumens in a tight beam is plenty for recreational lobster diving. Every diver should also carry a compact backup, because a dead primary ends the hunt and makes the swim home harder.
For members putting together a first lobster kit, the BigBlue Lobster Season Package with the AL1300NP is the one we point people to. It pairs BigBlue's 1,300-lumen, 10° narrow-beam light with a Morifish lobster bag for the price of the light alone. Browse the full dive lights collection for backup options, and our guide to choosing a dive light for more on beam angle and burn time.
BigBlue Lobster Season Package – AL1300NP 1300 Lumen Narrow Beam Light + Free Morifish Game Bag
A 1,300-lumen, 10° narrow-beam rechargeable light rated to 100 m, bundled with a Morifish lobster bag. A sensible complete setup for a diver's first lobster season.

A catch bag that closes itself
A lobster bag needs an opening you can feed a lobster into with one hand and that closes behind it, so the catch doesn't back out while you're measuring the next one. Waist-mounted bags keep your hands free and stay out of the way of your BCD inflator. Members who already own a light they like can pick up the Morifish Game Collection Lobster Bag on its own. Its bungee seal closes automatically, and a quick-release belt lets you drop it fast if it snags.
BigBlue Morifish Game Collection Lobster Bag – 14 x 24 in Heavy-Duty Nylon Mesh Waist Catch Bag
A 14 x 24 in low-profile waist bag with an auto-closing bungee seal and quick-release belt. For divers who already have a light and need a proper catch bag.

Gloves that stand up to spines
California spiny lobsters are covered in forward-pointing spines, and the den is usually lined with rock, urchins, and barnacles. Thin neoprene gloves get shredded quickly. A glove with an aramid palm holds up far better and still gives you enough grip to hold a lobster while you gauge it. The Waterproof G2 Aramid Diving Glove combines a Kevlar palm with 5 mm neoprene, which also keeps hands warm through a long night in temperate water. See the dive gloves collection for thinner options.
Waterproof G2 Aramid Diving Glove 5 Finger 5mm
A 5 mm five-finger glove with a full DuPont Kevlar palm and pre-bent fingers. It resists abrasion from rock and spines and keeps hands warm on cold-water night dives.

A gauge, a marker light, and surface signaling
Round out each diver's kit with a lobster gauge clipped to a retractor or lanyard, a whistle on the BCD, and a surface marker buoy per team. For night headcounts we also hand every diver a marker light at the briefing. The DiveCatalog.com Water Activated LED Signal Light turns on when it hits the water and off when it comes out, so no one forgets to switch it on, and it's inexpensive enough to buy a box as club gear. The safety and signaling collection covers buoys, reels, and audible signals.
DiveCatalog.com Water Activated LED Signal Light - Green
Switches on automatically in the water and off when removed. Clips to a tank valve, BCD, or mask strap so every diver shows up as a countable light at the surface.

Shore dive or boat charter?
Both work as club events, and the choice usually comes down to group size and experience.
Shore dives are cheap, flexible, and easy to open to newer members. Pick a site most of the group has already dived in daylight, with a clear, easy-to-find exit and little surge. Check that it's outside any MPA and that the beach or parking area is open after dark. Some aren't, and opening night is a bad night to find out.
Boat charters reach the island reefs and offshore structure where lobsters are often bigger and more plentiful, and the crew handles much of the logistics. The trade-off is cost and availability: opener charters out of Southern California ports tend to book up well ahead, so reserve a block of spots early and collect deposits when people sign up.
Running the night
Brief before dark
Hold the briefing before sunset while everyone can still see the site and your hands. Cover maximum depth and time, the route and turnaround point, the exit and what it looks like from the water at night, buddy pairs and entry order, light signals, the lost-buddy procedure, and the emergency plan. Then add the lobster-specific reminders: report cards filled in, gauges on, measure before bagging, and no tailing.
Appoint a surface marshal
One person stays dry, keeps the list of who is in the water and with whom, and ticks teams off at entry and exit. They should have a phone with signal, a charged light, and the local emergency and DAN numbers written on paper. Rotate the role across the season so it isn't always the same member missing the opener.
Hunt with good habits
Remind teams to settle on the bottom beside a ledge rather than on it, and to stay horizontal and off the reef when reaching in. Most lobsters are lost by lunging. Approach from the front, keep the light on the lobster, and make one committed grab at the base of the antennae or the body. If it backs deep into a hole, leave it. A missed lobster is not worth a silt-out, a damaged reef, or a hand wedged in a crack.
After the dive
Headcount first, before anyone starts breaking down gear. Count the marker lights at the surface, then count people on the beach or the boat against the marshal's list.
Then check catches against the gauge one more time and make sure everyone knows their report card needs updating for each location and gear type they used. Finally, do the part that makes the event worth running: somewhere warm with food, where newer divers can hear how the veterans find their spots. A club cookout the weekend after the opener — lobsters cooked whole, of course — is one of the easiest ways to bring members back for the rest of the season.
Frequently asked questions
When does lobster season open in California in 2026?
The 2026–27 recreational spiny lobster season opens at 6:00 p.m. on Friday, October 2, 2026, and closes at 11:59 p.m. on Wednesday, March 17, 2027.
How many lobsters can you take in California?
The bag and possession limit is seven spiny lobsters per person. Each one must measure at least 3¼ inches along the carapace, from the rear edge of the eye socket to the rear edge of the body shell.
Do kids need a lobster report card?
Yes, if they're taking lobster. Children under 16 don't need a fishing license, but anyone taking spiny lobster needs their own Spiny Lobster Report Card. Someone who only observes and doesn't fish doesn't need one.
Can you use a snare or tickle stick when diving for lobster in California?
No. Skin and scuba divers in California may take spiny lobster by hand only. Hooks, snares, spears, and tickle sticks are not allowed.
Do you need a special certification to dive for lobster?
No agency certification is required. Open Water certification plus a valid fishing license and report card are the legal minimums. Practically, you should be comfortable night diving and have solid buoyancy control, because hunting adds a lot of task loading. Newer divers learn fastest by joining an experienced hunter's team for their first season.
What happens if I don't return my lobster report card?
You'll pay a $21.60 non-return fee when you buy next season's card. Cards must be returned or reported online by April 30 after the season closes, even if you didn't catch anything.
Start planning this week
With the opener on October 2, the most useful thing a club organizer can do today is post the event, share the rule summary, and ask everyone to buy their report card now rather than at the last minute. Run a short bug night, build the teams, and keep the first outing small enough that you can keep track of everyone in the dark.
If you're putting together club gear or helping new members build their first lobster kit, the team at DiveCatalog can help. If your club is still getting organized, start with our guides to finding and joining a dive club and finding a dive buddy.
