About Liberia

April in Liberia is still mostly dry, with daytime highs around 31–35°C, so Palo Verde boat trips and Rincon de la Vieja hikes stay dusty and doable. By May and June the green season kicks in (about 30–33°C), bringing late-day downpours that cool things off and turn the hills neon. Crowds thin out and hotel rates soften, but mornings are clear enough for beach time at Playa Hermosa before the thunderheads stack up.

Tips for Liberia

• Book WestJet early (6–10 weeks out is usually the sweet spot); Liberia fares jump fast around holidays and March break.
• Pay with a no-foreign-transaction-fee card if you can—some add-ons or partner services may price in USD, and exchange rates add up.
• Liberia (LIR) is small but can bottleneck at immigration; sit near the front and have your onward/return details handy.
• If you’re heading to Tamarindo/Flamingo, pre-book a shuttle or rental—taxis are limited and prices vary.
