When Is Lobster Season in Maine?

When is lobster season in Maine? The honest answer is that Maine lobster is caught in every month of the year, but the fishery peaks in late summer and fall. If you specifically want new-shell (soft-shell) lobster, that softer, sweeter run generally starts in June and July and lasts into September.

So there is no single week to circle on a calendar. Think of the season as a curve rather than a switch: low in late winter and spring, rising through summer, and cresting in the fall. This guide covers what drives that curve, how new-shell and hard-shell differ, and why flash-frozen meat tastes like peak season no matter the month.

TL;DR

• Maine lobster is fished year-round, but the fishery peaks in late summer and fall.
• New-shell (soft-shell) season runs roughly June and July into September.
• New-shell is sweeter and more tender; hard-shell is firmer, holds more meat, and ships better.
• Winter lobster is excellent hard-shell, but tighter supply usually pushes prices up.
• Flash-freezing keeps peak-season meat at its best all year, so December meat can be September meat.

Is Maine lobster fished year-round?

Yes. Traps are in the water in every season, with inshore boats working hardest from summer into fall, when lobsters move closer to shore, while offshore boats keep fishing through winter in deeper water. Lobster is the backbone of the state's catch: per Maine Sea Grant, it accounted for more than 70 percent of the value of Maine's total commercial seafood landings in 2024. That scale is why supply never truly stops, though landings rise and fall with the season, and prices and availability tend to be best when the summer and fall catch is in full swing.

What drives Maine lobster availability?

There is no switch that turns the season on. Availability is the result of two forces pulling on each other. Water temperature is the engine: lobsters are cold-blooded, so they feed, move, and molt more as inshore water warms through the summer, and when the water is cold they are slower, eat less, and walk into a baited trap far less often. Weather is the quiet one. Winter storms cut the number of days a boat can leave the dock, so a stretch of rough weather tightens supply for everyone regardless of how many lobsters are on the bottom. That is why availability can shift week to week and not just season to season.

When is new-shell lobster season?

Lobsters grow by shedding their shells, and the biggest wave of molting happens as the water warms in summer. Right after a molt, a lobster wears a soft, thin new shell, which is where the name new-shell (or soft-shell) comes from. This run usually gets going in June and July and lasts into September, and the exact timing shifts by a few weeks each year with water temperature, so a warm spring can start it early. New-shell lobster is a local summer favorite: the meat is sweeter and more tender, and the shell is soft enough to crack by hand. The one trade-off is that a freshly molted lobster has taken on water, so it holds a bit less meat than a hard-shell of the same size.

How does a lobster molt?

A lobster wears its skeleton on the outside, so the only way to get bigger is to leave the old one behind. Under the existing shell it grows a soft new one, then absorbs water and cracks the old shell open at the seam between body and tail. Backing out is the hard part: the lobster pulls its whole body, legs, and claws through that opening, a slow and exhausting job, and comes out soft, floppy, and defenseless before taking on more water to swell into a larger size. Hardening takes weeks to months, and the meat fills in over the same stretch as the lobster feeds. Young lobsters do this several times a year, while larger adults molt far less often, which is one reason it takes 5 to 7 years to reach legal harvest size.

How do new-shell and hard-shell lobster differ?

As summer turns to fall, those soft shells harden and the meat fills back in, so by fall most lobsters have firmed up into hard-shell, with denser meat and more of it per shell. Neither is better across the board.

• New-shell: sweeter, more tender, softer shell, a little less meat, best eaten local.
• Hard-shell: firmer and denser, more meat per shell, and it ships and stores far better because the tougher shell protects the meat.

That durability is why most lobster shipped around the country, fresh or frozen, is hard-shell.

How does flash-freezing keep peak-season flavor year-round?

Here is the good news if you do not live on the coast: you do not have to wait for August to eat lobster at its best. We sort and cook lobsters by size to avoid overcooking, hand-pick and hand-debone the meat, then blast-freeze it soon after cooking. Rapid freezing at cryogenic temperatures locks in peak-season sweetness with no artificial preservatives, so what is in the bag reflects the condition of the lobster on the day it was processed, not the month you happen to open it. December meat can be September meat.

The meat stays at its best far longer than anything you freeze at home, and we still suggest using it within about 30 days of arriving for peak quality. Buy in packaging that lets you thaw in stages, so you thaw only what you need and keep the rest frozen and sealed, with no drip and no fishy freezer smell between the dock and your kitchen. For holiday cooking, order ahead of the week you need it, since shipping runs tighter around holidays for everyone and frozen meat keeps perfectly well until the day you want it.

Why does the Maine lobster season come back every year?

Maine's season holds up year after year because the fishery is carefully managed. Lobsters take 5 to 7 years to reach legal harvest size, both minimum and maximum size limits protect the youngest and the largest breeding lobsters, and fishermen v-notch and release egg-bearing females so they keep reproducing, a practice going back generations. NOAA lists U.S. American lobster as sustainably managed and the Gulf of Maine stock as not depleted, though a 2025 assessment flagged a decline and a marginal level of overfishing that regulators are watching. Our guide to lobster sustainability covers that full picture.

Is winter lobster good, and why do prices move?

Winter lobster is genuinely good, and a lot of people are surprised by that. Those lobsters have been hard-shell for months, so the shells are thick, the meat is packed in tight, and the yield per lobster is at its best. What changes in winter is not quality but supply: fewer boats fish, trips run longer and further offshore, and storms take days off the calendar, so less product moving and higher costs to land it usually push winter prices above summer prices. The honest summary is that prices move constantly with landings, weather, fuel, demand, and shell condition, which is why the useful question is not what lobster costs but when the meat is at its best.

How should you buy month by month?

You do not need a calendar with circled dates, just a rough sense of what each stretch is good for. The pattern below is a tendency, not a guarantee, since every year runs a few weeks early or late depending on how the water warms.

• Late winter into spring: lighter landings and full-meat hard-shell lobster. A good time to buy picked frozen meat rather than fight a thin fresh market.
• Late spring into early summer: the fishery ramps up as water warms and lobsters move inshore. Supply builds week by week.
• Midsummer: new-shell lobster arrives and volume climbs. The stretch to eat whole lobster in Maine, cracked by hand.
• Late summer into fall: the peak. Shells are hardening, meat is filling back in, and supply is at its strongest.
• Late fall into the holidays: quality stays excellent while supply tightens and demand rises, so order early rather than late.

Want peak-season flavor in any month?

The beauty of buying picked meat is that the season stops mattering. Because it is hand-picked and blast-frozen soon after cooking, a bag opened in February reflects the day it was processed, not the month you are in. Maine Shelled Lobster's claw and knuckle meat brings peak-season sweetness to your table any time of year. Keep it frozen until you are ready, thaw only what you need, and cook.

Frequently asked questions

What months is lobster season in Maine?

Maine lobster is fished year-round. The fishery peaks in late summer and fall, and new-shell (soft-shell) season runs roughly June and July into September.

Is soft-shell or hard-shell lobster better?

It depends on what you want. Soft-shell (new-shell) is sweeter and more tender, while hard-shell is firmer, holds more meat, and ships better.

Can you get good Maine lobster in winter?

Yes. Offshore boats fish through winter, and hand-picked, flash-frozen meat holds peak-season quality no matter the month.

Why is fall a good time for Maine lobster?

The fishery peaks in late summer and into fall, so supply is strong and the meat is at its best, with shells hardened and meat filled back in.

Is lobster better in summer or winter?

They are different, not ranked. Summer brings new-shell lobster that is sweeter and more tender, while winter lobster is hard-shell with denser, fuller meat and a better yield per lobster.

Why is lobster more expensive in winter?

Fewer boats fish, trips are longer, storms cost fishing days, and holiday demand is high. Less supply and higher costs to land it usually mean higher prices.

Does the season change the frozen lobster meat I buy?

No. Meat is picked and blast-frozen soon after cooking, so a bag opened in February reflects the day it was processed rather than the month you are in.
