May is a transitional month with increasing humidity and more frequent afternoon showers as the wet season approaches. Coastal and lowland conditions become less predictable. Travelers should be prepared for occasional downpours that can interrupt outdoor plans.

Average temperature across Honduras in May.
Roatán, Utila, Guanaja
May marks the transition into the wetter half of the year; showers become more frequent though diving is still excellent between storms. Utila can be muggy and some small operators scale back schedules during rainy spells, so confirm dive plans in advance. The main hazard to watch is the start of the Atlantic storm season - keep an eye on forecasts if planning open-ocean crossings.
La Ceiba, Tela, Trujillo
May is the run-up to the rainier months and La Ceiba comes alive with preparations for its big Carnival in mid-May; expect big crowds and festive noise if timed to that weekend. Rain begins to fall more regularly later in the month, sometimes in heavy bursts that swell rivers quickly and can disrupt road crossings. Bring sturdy footwear for muddy trails and confirm transfers if you plan coastal boat hops during stormy afternoons.
Puerto Lempira, Río Plátano
May marks the start of a pronounced wet season: rivers swell rapidly and many overland tracks become impassable, pushing travel to river and coastal routes instead. The Río Plátano turns full and brown with nutrient-rich floodwaters - a dramatic time for birding from boats but difficult for trekking. Expect reduced services in remote lodges and plan for muddier conditions and abundant mosquitoes.
La Tigra, Celaque, Comayagua
May signals the start of the wet season in the highlands and mountain trails grow mossy and slippery as afternoon rains pick up; mornings are still often clear. La Tigra becomes leafier and streams run stronger - rewarding for waterfall lovers but tricky for independent hikers. Guide-led treks are recommended as paths can be indistinct; carry waterproof layers and anticipate cooler, damp nights at altitude.
San Pedro Sula, Puerto Cortés
May signals the start of the rainy season for the Sula Valley; showers turn more regular and heavy storms can lead to urban flooding in low-lying San Pedro Sula neighborhoods. Infrastructure disruption is possible during intense downpours, so allow extra time for transfers and be cautious crossing flooded streets. If planning national parks visits, hire a local guide who knows current trail conditions and river levels.
Choluteca, Amapala, El Triunfo
May signals the onset of the rainier months on the Pacific side, with occasional heavy showers that refresh the landscape but can churn coastal waters and create strong runoff near river mouths. Road approaches to remote beaches may become patchy, and small-boat operators adapt schedules around afternoon storms. Travelers should plan flexible departures and waterproof luggage for sudden downpours.
There are no major festivals or events in Honduras during May to be aware of.
