Belize packs an outsized punch for a country smaller than New Hampshire. Its Caribbean coast shelters the Western Hemisphere's longest barrier reef, a UNESCO World Heritage Site where nurse sharks drift through warm turquoise shallows and the Great Blue Hole drops into an abyss that once captivated Jacques Cousteau. Inland, ancient Maya cities like Xunantunich and Caracol rise above thick jungle canopy, while cave systems hold ceremonial pottery and skeletal remains left by the Maya centuries ago. The culture is just as layered: Creole, Maya, Mestizo, and Garifuna traditions converge in a place where English is the official language, fry jacks with beans and Marie Sharp's hot sauce start every morning, and Garifuna drumming echoes through coastal villages like Hopkins and Dangriga.
Your prime window runs from mid-March through late May, when Belize's dry season is at its driest and the tropical heat stays manageable. April sees rain on roughly 6% of days, making it one of the driest months of the year, and humidity sits at its lowest point. This stretch catches the tail end of peak season crowds in March before visitor numbers thin out in April and May, giving you better availability on the cayes and at jungle lodges. It's also when Easter festivities bring the Holy Saturday Cross Country Cycling Classic, a beloved race from Belize City to San Ignacio, and the Cashew Festival fills Crooked Tree Village with live punta music and cashew wine in mid-May. If this window doesn't work, the winter dry season from December through February is a strong backup, though expect higher prices and the biggest crowds of the year.
Spring in Belize
March through May is when Belize's weather and visitor rhythm hit their sweet spot. The dry season is still going strong, and April stands out with rain falling on only about 6% of days. Highs average 87.8°F (31°C), warm enough for full days on the reef but not the oppressive heat that arrives later. Mornings start at 75.3°F (24.1°C), comfortable for early hikes to Maya sites like Xunantunich in the Cayo District, where you can climb the El Castillo pyramid for panoramic jungle views without soaking through your shirt before 9 AM.
Easter week is a major event across the country. The Holy Saturday Cross Country Cycling Classic draws huge crowds along the highway from Belize City to San Ignacio, and the town of Benque Viejo del Carmen hosts traditional Semana Santa processions. In mid-May, the village of Crooked Tree celebrates the Cashew Festival, where local women harvest the nuts and the whole community gathers for cashew wine, cashew ice cream, punta music, and Caribbean cooking. Labour Day in early May is a public holiday, so plan for some business closures.
March remains the busiest tourism month, so expect higher prices and crowded snorkeling tours at Hol Chan Marine Reserve. By April and May, the cayes quiet down noticeably, and you'll find better deals at beach resorts on Ambergris Caye and Placencia. A gentle breeze picks up in May, the windiest month at around 7.2 mph, keeping conditions pleasant on the water for sailing and kayaking trips. Pack reef-safe sunscreen, a wide-brimmed hat, and sturdy shoes with good grip if you're heading into cave tubing at the Caves Branch river system.
Summer in Belize
Summer marks the shift into Belize's wet season, and the heat becomes a serious factor. Highs average 89.1°F (31.8°C) with lows settling at 78.1°F (25.6°C), meaning nights offer little relief. By mid to late August, peak temperatures push to 90.1°F (32.3°C) with overnight lows of 77.6°F (25.3°C). The humidity combined with that heat makes jungle excursions like the ATM Cave or the Black Hole Drop at Caves Branch significantly more taxing. Rain chances climb to roughly 28% to 34% of days across these months, typically arriving as heavy afternoon downpours that clear within an hour or two.
This is also Atlantic hurricane season, which runs through November. While direct hits on Belize aren't annual events, tropical storms and depressions can disrupt travel plans, especially on the cayes where water taxi service halts in rough seas. The upside: visitor numbers drop considerably, and accommodations are priced at a discount. You'll have popular dive sites like the Great Blue Hole and Shark Ray Alley largely to yourself. Lobster season opens in July, and coastal towns including Placencia, Caye Caulker, and San Pedro celebrate with lobster festivals featuring grilled tails, ceviche, and the crowning of a Miss Lobster.
Pack lightweight, moisture-wicking clothing and a quality rain jacket rather than an umbrella, which is useless on a boat. Bug repellent is essential for jungle areas, where mosquitoes are at their most active during the wet months. The long days of summer, with sunset not arriving until after 6:30 PM in June and July, give you extra hours for snorkeling trips and sunset drinks at the Split on Caye Caulker.
Fall in Belize
Fall is the quietest and wettest period in Belize. October, the wettest month, sees rain on about 35% of days, and September isn't far behind at 37%. Highs average 87.1°F (30.6°C) with lows of 74.4°F (23.6°C), a touch cooler than summer but still thoroughly tropical. Hurricane season remains active through November, and the higher rainfall can make unpaved roads to remote sites like Caracol or Mountain Pine Ridge impassable. September is the single least-visited month, and accommodation prices drop to their lowest levels of the year.
September carries patriotic energy despite the weather. Saint George's Caye Day in mid-September commemorates a historic naval battle with ceremonies, parades, and street festivals nationwide. Independence Day follows shortly after in late September with fireworks, street fairs, and dancing to Caribbean and Latin beats in Belize City and towns across the country. These two holidays back to back create a festive two-week stretch. In October, the Belize Birding Festival in Belize City brings together conservation organizations and birding enthusiasts, a fitting event for a country that hosts more than 600 bird species.
November's signature cultural event is Garifuna Settlement Day on the 19th, when the towns of Dangriga, Hopkins, and Punta Gorda erupt with celebrations. A dawn reenactment of the Garifuna landing by dugout canoe kicks off a week of parades, drumming competitions, and traditional food like hudut and cassava bread. If you visit during fall, waterproof bags for electronics are non-negotiable, and you'll want quick-dry clothing for the frequent showers.
Winter in Belize
Winter is Belize's high season, and for good reason. The dry season is in full effect, with highs averaging a comfortable 83.6°F (28.7°C) and lows around 70.5°F (21.4°C), the coolest readings you'll find all year. Rain still falls on roughly 25% of days in December, tapering to about 10% in February, one of the driest months. The lower humidity and cooler evenings make this the most pleasant time for combining beach days on Ambergris Caye with inland adventures in the Cayo District.
December through February draws the heaviest crowds, with March technically the busiest month but the winter holiday rush pushing December's visitor index almost as high. Expect premium pricing at resorts across the cayes and along the Placencia Peninsula, and book snorkeling and diving excursions well in advance. The Placencia Sidewalk Art Festival, typically held in February, fills the village's famously narrow main sidewalk with local art, woodcarving, and Garifuna music. Carnival also falls in February, with San Pedro on Ambergris Caye hosting colorful parades, elaborate costumes, and street parties that blend African-Caribbean, Maya, and Mestizo traditions.
The Hummingbird Highway connecting Belmopan to the coast is at its most scenic during the dry months, when waterfalls are accessible and the jungle canopy is lush from late-season rains. Pack a light layer for early morning boat rides to the cayes, where the breeze off the Caribbean can feel cool at 70.5°F (21.4°C). A good pair of water shoes will serve you everywhere from river hikes at Big Rock Falls to wading out to the reef at Hol Chan.

Travel Tips & Safety for Belize
Belize is an English-speaking country, which makes navigating logistics straightforward for most visitors. Getting between the coast and cayes is easy via water taxi from Belize City to Ambergris Caye and Caye Caulker, and domestic carriers Tropic Air and Maya Island Air connect the islands with the mainland and Placencia. On the cayes, golf carts and bicycles are the primary way to get around, since cars aren't practical on the narrow island roads. On the mainland, renting a car is useful for reaching the Cayo District or driving the Hummingbird Highway, but roads can be rough and poorly lit at night.
Use standard tropical precautions: drink bottled water in rural areas, apply reef-safe sunscreen liberally (the equatorial sun is punishing even on overcast days), and carry bug repellent with DEET for jungle excursions. Petty theft can occur in Belize City, particularly around the tourist district after dark, so keep valuables out of sight and stick to well-traveled areas at night. On the islands and in towns like San Ignacio and Placencia, the atmosphere is considerably more relaxed.
