Biloxi in December

March through May brings perfect weather — highs in the 70s and 80s without the crushing humidity. Spring break crowds hit in March, so book early or pay more. April and May offer the sweet spot of great weather and reasonable prices. Fall returns in October and November with comfortable temps and fewer crowds. Hurricane season technically runs through November, but most storms hit earlier in the season. Check weather forecasts before booking. Summer means swamp-level humidity and afternoon thunderstorms, but also the lowest hotel rates. If you can handle 95-degree heat that feels like 110, you'll find casino rooms for $49 a night. Just plan indoor activities from noon to 4 PM. Winter brings mild days and cold nights. Casinos stay busy with snowbirds, but beach activities are limited. December through February offers decent deals if you're mainly here for gambling and seafood.
