Driving in Costa Rica's rainy season is very doable, and the country is at its greenest. You just need a bit more time, daylight driving and, for rural roads, a 4x4. Main highways stay open and paved, but gravel and mountain roads can turn muddy and slippery. Here is our local advice for a safe trip.
When is the rainy season?
Across most of the country, the rainy or "green" season runs roughly from May to November. Mornings are often clear and the rain tends to come in the afternoon. The Caribbean coast follows a different pattern, so if you are heading to Puerto Viejo, ask us about conditions for your dates.
Do you need a 4x4 in the rainy season?
If you plan to leave the main highways, yes. Unpaved and rural roads lose grip when wet, and a 4x4 gives you better traction and more ground clearance. For destinations such as Monteverde, Santa Teresa or the Osa Peninsula, we recommend a 4x4 all year, and even more in the rainy months. On paved routes to La Fortuna, Manuel Antonio or Tamarindo, any of our vehicles works. More in our honest guide: do I need a 4x4 in Costa Rica?
8 tips for driving in the rain
- Drive in the morning. Plan long drives early, before the usual afternoon rain.
- Avoid driving after dark. Rain, fog and unlit rural roads are a hard combination.
- Never drive into a flooded river or road. Water depth and current are hard to judge. A 4x4 gives you grip, not permission to cross. If in doubt, wait or turn back.
- Add extra time. Count on slower driving and possible delays on mountain roads.
- Watch for landslides and fallen branches on mountain roads after heavy rain.
- Slow down and keep your distance. Wet roads need longer braking.
- Use a navigation app with live traffic and check road conditions before you leave.
- Fill up when you can. Gas stations can be far apart in rural areas.
Which vehicle to choose for the green season
- Compact 4x4: couples on a budget who want 4x4 traction.
- Mid-size SUV 4x4: more clearance and space for luggage.
- 7-seat 4x4: families and groups on rural routes.
