Crawfish season typically runs from about late winter through early summer, with the very best eating usually in spring.

Core crawfish season

  • In much of Louisiana and the Gulf Coast, crawfish can show up as early as November and last until around June or July, depending on weather and rainfall.
  • The most dependable window for good, plentiful crawfish is usually February through May.

Peak time for the best crawfish

  • Many producers and chefs point to March–May as the peak months, when crawfish are largest, more plentiful, and easier to peel.
  • In places like Louisiana and Texas, mid‑March through late May is often when you get the classic big-boil, big-bug experience at its best.

Why the dates can shift

  • Crawfish are sensitive to temperature and rainfall, so warm, wet winters can start the season earlier and extend it, while cold or dry conditions can delay or shorten it.
  • Farmed crawfish can broaden the season, sometimes making live crawfish available from roughly January into summer, though quality still peaks in spring.

Simple takeaway

If you’re planning a boil and want the best mix of size, price, and availability, aim for March through May; if you’re just asking “when is crawfish season,” think late winter to early summer in the southern U.S.
