Biloxi sits on Mississippi's Gulf Coast, a city shaped by centuries of French, Spanish, and Southern heritage, where white sand beaches stretch along the Mississippi Sound and casino resorts light up the shoreline. Once known as the Seafood Capital of the World, this coastal town still delivers some of the Gulf's best shrimp, oysters, and gumbo at restaurants ranging from fine dining spots to no-frills waterfront joints. Eight casinos line Beach Boulevard alongside historic landmarks like the 1848 Biloxi Lighthouse and the Ohr-O'Keefe Museum of Art, making this a place where you can kayak to a barrier island in the morning, tour a Civil War estate in the afternoon, and catch a live show at a resort by night.
The best time to visit Biloxi is early October through early December, when temperatures feel comfortable, rain is at its lowest, and the coast comes alive with signature events like Cruisin' the Coast and the Biloxi Seafood Festival. Expect highs near 79.4°F (26.3°C) that taper into the low 60s by December, with October delivering the driest conditions of the year. A strong secondary window runs from early March through early May, when spring brings mild weather, the Crawfish Music Festival, and Mardi Gras celebrations in some years, all with lower hotel prices and thinner crowds. One note for late November travelers: expect a brief spike in crowds and prices around Thanksgiving week, when conditions can dip slightly.
Spring in Biloxi, MS, US
Spring on the Mississippi Gulf Coast is when Biloxi shakes off its quiet winter months without yet tipping into summer's swelter. Afternoons warm to highs of 77°F (25°C), comfortable enough for long stretches on the beach or a kayak trip out to Deer Island, the undeveloped barrier island just offshore. Mornings can still be cool at 60.7°F (15.9°C), so pack a light layer if you plan to catch an early shrimping excursion from the Small Craft Harbor. In years when Fat Tuesday falls in late February or March, Biloxi's Mardi Gras parades roll through downtown with costumed krewes, bead tosses, and a distinctly smaller-town energy compared to New Orleans, which sits just 90 minutes to the west.
April brings the annual Crawfish Music Festival at the Mississippi Coast Coliseum, a weekend event built around boiled crawfish, live music headliners, and midway rides. March also hosts the St. Patrick's Day parade through downtown and Grillin' on the Green, a BBQ cook-off at Biloxi Town Green. Showers are sporadic this time of year, with roughly one to two wet days per month, and Gulf breezes keep things from feeling stagnant. Tourism is moderate, and hotel rates tend to be lower than summer or fall peak periods, making spring a smart time to score deals on beachfront rooms.
By May, a ceremonial Blessing of the Fleet marks the opening of shrimp season, a tradition tied to Biloxi's deep Vietnamese and Croatian fishing heritage. Water temperatures climb above 70°F, making swimming and paddleboarding genuinely enjoyable. Bring sunscreen and a wide-brimmed hat; the sun gets serious quickly even before the calendar turns to summer.
Summer in Biloxi, MS, US
Summer is when Biloxi draws its biggest crowds, with families and weekend gamblers filling the casino resorts along Beach Boulevard. The trade-off is the heat: seasonal highs average 90.1°F (32.2°C) with lows that barely dip to 75.2°F (24°C), leaving the air thick and heavy well into the evening. Early to mid-August brings the peak, with highs reaching 92.1°F (33.4°C) and overnight lows hovering at 76.9°F (24.9°C). Humidity compounds the effect, so plan beach time for mornings and save your casino visits and museum stops for the hottest afternoon hours.
July is the wettest month of the year, with roughly a 32% chance of significant rain on any given day. Afternoon thunderstorms roll in fast off the Gulf, usually clearing within an hour but occasionally dumping impressive amounts of water. June kicks off with the Mississippi Coast Coliseum Summer Fair, a local tradition marking the start of the season with rides, food vendors, and live entertainment. Deep-sea fishing charters run at full capacity, and the long summer evenings, with sunset not arriving until nearly 8pm, stretch the day for waterfront dining.
This is also peak hurricane season along the Gulf Coast, and while a direct hit in any given year is unlikely, it's worth monitoring forecasts and understanding your hotel's cancellation policy. Accommodation prices run higher than the rest of the year, and the most popular resorts like Beau Rivage and Margaritaville book up weeks in advance. Pack lightweight, moisture-wicking clothing, a refillable water bottle, and strong sunscreen if you visit during these months.
Fall in Biloxi, MS, US
Fall is Biloxi's sweet spot. Temperatures settle into a comfortable range with highs of 79.4°F (26.3°C) and lows of 60.9°F (16.1°C), the kind of weather that feels just right for a full day outdoors. October is the driest month of the year, with only about a 12% chance of rain, and the lower humidity makes the coast feel noticeably more pleasant than the summer months. September hosts the annual Biloxi Seafood Festival on the Town Green, a celebration of the Gulf Coast's fishing heritage featuring gumbo cook-offs, live music, and seafood prepared by local restaurants and vendors.
The headline event of the season is Cruisin' the Coast, typically held in early to mid-October. This week-long classic car festival draws over 10,000 vintage vehicles from across the country, cruising a 30-mile stretch of Highway 90 with sock hops, swap meets, car auctions, and live entertainment at stops from Bay St. Louis to Ocean Springs. It's the busiest tourism week of the year, so book accommodations well in advance. In November, the nearby town of Ocean Springs hosts the Peter Anderson Festival, drawing artists, crafters, and food vendors from around the country for a weekend of art and live entertainment.
Precipitation picks up slightly in November to around 15%, and the occasional shower is worth having a packable rain jacket for. October is the peak tourism month by volume, but November quiets down, and you'll find shorter lines at the Biloxi Lighthouse, the Maritime and Seafood Industry Museum, and the Beauvoir estate. A light jacket is smart for evening waterfront walks as temperatures cool after sunset.
Winter in Biloxi, MS, US
Winter transforms Biloxi into the quietest version of itself, with thinner crowds and a slower pace along Beach Boulevard. Highs average 63.3°F (17.4°C) with lows dropping to 45.5°F (7.5°C), cool enough to need a jacket but mild compared to most of the country. Snow is essentially nonexistent here. Early December brings the annual Christmas on the Water boat parade, when decorated vessels cruise between the Small Craft Harbor and Casino Row, capped off with a fireworks display visible from the beach.
December tends to be the most humid month of the year, and rain chances hover around 23%, though late December typically sees the driest individual stretch of the entire year. January and February are the quietest tourism months, meaning you'll have the casinos, restaurants, and historic sites largely to yourself. The Ohr-O'Keefe Museum of Art and the Maritime and Seafood Industry Museum make excellent rainy-day stops when the weather turns gray. Hotel rates drop to their lowest levels, and you can often find significant deals at the resort properties.
The days are shorter, with sunset arriving before 5pm through much of December and January, so plan outdoor activities for the middle of the day. In years when Mardi Gras falls in February, the parade season begins with early krewe events and the famous Mardi Gras Bed Race through downtown. Bring layers you can peel off during warmer afternoons; even in winter, midday sun along the Gulf can push the temperature well above the morning chill.
