When planning meetings, events, and incentive programs in Costa Rica, it’s easy to assume the weather follows a simple pattern: rainy season means constant downpours, and sunny season means endless sunshine. But the reality is much more nuanced. With its diverse microclimates and ever-changing conditions, the weather isn’t always straightforward—but that's part of the enchantment and no reason to shy away from choosing Costa Rica as your destination. 

Here are six common misconceptions about Costa Rica's weather and the truths behind them.

#1 The weather is the same everywhere in Costa Rica

Reality: Costa Rica's weather varies greatly due to its diverse geography and microclimates, leading to different conditions across the country. For example, the Pacific coast experiences a distinct dry season from December to April with hot, sunny days, and a rainy season from May to November with afternoon showers. Meanwhile the highlands around Arenal Volcano actually have more Caribbean-feeling weather, where you'll have the best weather between December and April, as well as September and October.

In the Central Valley, cities like San José enjoy mild, spring-like temperatures averaging around 22°C (72°F). Even the typically warm and dry Guanacaste shows microclimatic variations between its sunny beaches and soaring volcanoes. 

#2 Myth: Costa Rica is always hot and sunny

Reality: While Costa Rica is a tropical country, it has diverse microclimates. The weather varies significantly between regions—coastal areas are typically warm and humid, but the highlands and mountainous regions can be cool, especially in the evenings. The hottest, driest province in Costa Rica is Guanacaste, which enjoys the most sunny days per year—however, even Guanacaste experiences a green season! 

#3 Myth: The rainy season is a constant downpour

Reality: The green season (roughly May to November) doesn't mean non-stop rain. In most regions, mornings are often sunny with rain showers occurring in the afternoon or evening. The mid Pacific coast and Central Valley can still enjoy several dry hours each day, making it possible to enjoy outdoor activities even during the rainy season. In Guanacaste, the green season tends to be lighter, with heavier rain occurring mainly between August and October. 

#4 Myth: The rainy and dry seasons are straightforward

Reality: While Costa Rica does have distinct dry (December to April) and rainy (May to November) seasons, some areas like the Caribbean coast can experience rain year-round with more unpredictable weather patterns. This region, as well as some other microclimates, don’t strictly follow the country's typical dry and rainy seasons. 

#5 Myth: You should avoid visiting Costa Rica during the green season

Reality: Costa Rica can be enjoyed year-round! While October tends to be the rainiest month, the rest of the green season still offers plenty of opportunities for exploration. Mornings are often sunny, with rain typically in the afternoons, and the landscapes are lush and vibrant. Plus, visiting during this time means fewer crowds and the chance to experience the country’s rich biodiversity at its greenest.

#6 Myth: Hurricanes are a threat in Costa Rica

Reality: Costa Rica is relatively sheltered from hurricanes due to its position near the equator and south of Nicaragua. While nearby countries in Central America can be affected by hurricanes, Costa Rica typically experiences only residual rain and wind from distant storms, making it less prone to the direct impact of hurricanes.

The Main Takeaway: Costa Rica is truly a year-round destination

The key is to plan your program itinerary thoughtfully, taking into account the local weather patterns of the region you’re visiting. Whether it’s making the most of sunny mornings with early excursions or exploring lush, green landscapes that thrive in the rain, there’s always a way to enjoy what Costa Rica has to offer. By embracing the weather and planning around it, you can create a memorable trip that showcases the best of this beautiful country, no matter when you choose to visit.
