Guatemala Weather & Climate

November through April (dry season) is the most consistent travel window. Clear skies, optimal volcano conditions, and no afternoon rains make logistics easier. February and March offer the widest choice of activities and the best visibility for sunrise photography at Tikal and Acatenango.

May through October (wet season) has real advantages: vivid green landscapes, lower prices, fewer tourists, and the peak of sea turtle season on the Pacific coast. Morning hours are reliably clear even in the wettest months. The dry season drawback is that January through March is peak tourist season with highest prices and advance booking requirements.

Guatemala has two main seasons defined by rainfall rather than temperature. The dry season (November through April) brings clear skies, dusty roads, and optimal visibility for volcano and highland views. The wet season (May through October) brings daily afternoon rains starting around 2pm that last 2 to 3 hours, leaving mornings brilliantly clear.

Temperature variation between seasons is modest at highland elevations; Antigua averages 73 to 82F year-round. The real seasonal difference is sky clarity, road conditions in remote areas, and whether afternoon activities are possible outdoors.

At Antigua (1,530m), lows rarely drop below 50F even in the coldest months. But Guatemala has dramatic elevation contrasts. Acatenango summit camp at nearly 4,000m drops to near-freezing in December and January. The Cuchumatanes highlands around Quetzaltenango can approach 32F on cold dry-season nights. Tikal and the Pacific coast, by contrast, rarely drop below 65F.

The practical message: never assume Guatemala is warm everywhere. Pack a warm layer and waterproof shell regardless of the season if your itinerary includes highlands or volcano camps.

Lightweight, breathable clothes for Antigua and coastal warmth. A mid-layer fleece or down jacket for highland evenings and nights. A fully waterproof rain jacket for afternoon rains in the wet season and cold, wet conditions on volcanoes. Sturdy hiking boots for volcano treks and Peten jungle trails.

SPF 50+ sunscreen and a wide-brimmed hat for all outdoor activity. Insect repellent (DEET 30%+ or picaridin 20%+) for all lowland and coastal areas, particularly for dawn and dusk. A headlamp for early morning Tikal access and overnight volcano camps. Modest clothing for visiting highland Maya communities and churches.

Lake Atitlan at 1,562m shares Antigua's near-eternal spring climate. Daytime highs average 72 to 80F throughout the year. Nights are cooler, dropping to the mid-50s in the dry season. The defining weather feature at Atitlan is not rain or temperature but the Xocomil wind, which picks up between 1 and 3pm most days, creating significant waves on the lake.

Complete all lancha boat trips between villages before noon. In the wet season, dramatic afternoon cloud formations over the three surrounding volcanoes create extraordinary photography conditions. The lake is most photogenic in the wet season despite (or because of) the rain.

For the right traveler, yes. The wet season (May through October) delivers Guatemala at its most verdant and dramatic. Mornings are reliably clear for all outdoor activities. The Tikal jungle glows with intensity. The Pacific coast sea turtle releases peak in September and October. Prices are lower and crowds thinner at every destination.

The practical challenge is that afternoon activities after 2pm outdoors are not guaranteed, some jungle and highland tracks become muddy and difficult, and El Mirador's 82km jungle trek is generally not viable in the wet season. EcoVoyager designs wet-season itineraries around morning schedules.

The Peten lowlands are hot and tropical. The dry season (November through April) is the most comfortable for visiting Tikal, with temperatures in the mid-80s to low 90s by midday. March and April before the rains are the hottest months, with temperatures regularly reaching 95F or above. The humidity is consistently high year-round.

The sunrise visit at Tikal from Temple IV is one of Guatemala's signature experiences and requires arriving at the site before 5am. In the wet season this is the best part of the day; in the dry season all morning hours are comfortable. Avoid midday Tikal in February through April; the heat is intense in the jungle clearing around the main plaza.

Dramatically. Guatemala's 37 volcanoes and extreme elevation range create one of the world's most compressed climate gradients. Tikal in the Peten at 200m reaches 95F in March; Antigua at 1,530m is a comfortable 75F on the same day; Acatenango at 3,976m is below 40F at the summit overnight. All three are within a 5-hour drive of each other.

The practical advice: plan your packing around your highest and lowest elevation destinations, not just the main one. Even the most Antigua-focused itinerary can include half-day excursions to 1,000m of elevation change. A packable down jacket and waterproof shell occupy little space and earn their weight on every Guatemala trip.
