Venezuela has two main seasons: dry (roughly November to April) and rainy (May to October). The distinction matters more for some regions than others.
Dry season (November–April) is generally the easiest time to travel. Roads in the interior are more passable, jungle hikes are less muddy, and the weather at the coast is reliably sunny. January and February are particularly pleasant across most of the country — temperatures are comfortable and rain is rare. This is also peak season for Los Roques and the Caribbean coast.
Rainy season (May–October) is not off-limits by any means. Waterfalls, including Angel Falls, are at their most spectacular when water levels are high — the falls can reduce to a trickle in the driest months. The southern highlands and tepui country are most dramatic after rain. Mornings are typically clear; rain usually comes in afternoon downpours rather than all-day drizzle.
For specific regions:
Angel Falls and Canaima — July to October for maximum flow; the falls can be disappointing (or invisible in cloud) during the dry season. February to April is clearest for visibility but water levels are lower.
The Andes (Mérida) — Temperature is the bigger factor here than rain. Mérida sits at 1,600m and is cool year-round (16–22°C). The highest cable car station at Pico Espejo (4,765m) is cold at any time of year.
Los Roques and the Caribbean coast — The dry season coincides with peak beach weather. The coast can catch brief showers even in the dry months, but nothing significant.
Gran Sabana and tepui country — The dry season (December–April) gives clearer skies for views of the tepuis; the rainy season produces more dramatic waterfalls and greener landscapes.
The Christmas and Carnival periods (late December to February) are busy for domestic tourism, especially at beach destinations. Book ahead.
