Where to Go in Guatemala in May
Pacific Coast & Southern Lowlands
Monterrico, Sipacate, Puerto San José
May signals the start of the rainy season with increasing afternoon and evening downpours; mornings are still fine for boat trips and beach walks but expect sudden showers. Rivers that cut across the coastal plain swell quickly after storms, so low bridges and beach accesses may be temporarily disrupted; local drivers are used to the change but build slack into itineraries. Surfing can remain good between showers and turtle tours continue with wet-weather alternatives for evenings.
Central Highlands
Antigua, Guatemala City, Lake Atitlán, Panajachel
The first heavy showers usually begin in May, cutting many highland gardens back into lush green almost overnight; Antigua’s cobblestones get slippery and waterfalls around Lake Atitlán swell. Day trips are still very doable - morning excursions to viewpoints are often dry - but plan for afternoon downpours and occasional temporary mud on hiking trails. Fewer tourists than in the dry season make this an attractive time for a quieter visit provided you have flexible plans.
Western Highlands & Sierra de los Cuchumatanes
Quetzaltenango/Xela, Huehuetenango, Todos Santos
May typically marks the onset of more regular showers at higher elevations, turning meadows and hillside terraces a vivid green and swelling mountain streams - trails become noticeably muddier and more technical. Trekking remains possible in the mornings but expect afternoon rain and fog in the Cuchumatanes, which can reduce visibility for summit attempts. Local transport can be slower after heavy downpours; waterproof boots and gaiters are recommended.
Petén & Maya Lowlands
Flores, Tikal, Yaxhá
May marks the onset of more regular rains in the Petén, yet mornings typically remain usable for temple visits and canopy walks before storms build. The jungle takes on an intense green and waterfalls in sinkhole areas pick up; however, afternoon showers can be heavy and persistent, interrupting longer trekking plans. Boat and river services continue but expect occasional cancellations or delays during squally weather.
Caribbean Coast & Izabal
Puerto Barrios, Río Dulce, Livingston, Izabal lake
May signals the shift to the wet season with more frequent heavy showers and rising river levels in Izabal; Río Dulce can swell, altering docking and transfer schedules to lodges. Boat captains work around afternoon storms, so plan for morning travel and accept occasional delays on river crossings and lake transfers. Mosquitoes increase with standing water, so bring effective repellent and consider netted accommodations if sensitive.
