Green Season’s Grand Opening

Imagine stepping into a world where the jungle hums with fresh rain, the air smells of earth and blossoms, and the crowds haven’t yet arrived. May in Costa Rica is the green season’s curtain-raiser—a month of transition where the dry days fade and the rains begin to sprinkle life across the land. It’s not the sun-soaked peak of December, but it’s a lush, vibrant escape for those who crave nature’s raw energy. From Pacific swells to Caribbean calm, here’s your guide to May in Costa Rica—weather quirks, top adventures, and all.

May Weather: Pros and Cons

May marks the shift from dry to wet, bringing a mix of sun and showers that shapes a unique travel vibe.

• Pros: The landscape transforms into a neon-green paradise as rains revive rivers and forests. Prices drop from high-season highs, and tourist hotspots feel blissfully quiet. Mornings often stay dry, giving you a window for outdoor fun.
• Cons: Afternoon showers are the norm, and humidity climbs. Some trails turn muddy, and rural roads might get tricky. Flexibility is your friend.

Unlike the dry, bustling December weather in Costa Rica—perfect for beach-packed days—May offers a softer, greener take on paradise.

Microclimates: A Weather Symphony

Costa Rica’s small size belies its wild microclimate diversity, and May plays every note.

• Pacific Coast (Guanacaste, Malpais, Santa Teresa, Tamarindo, Nosara, Nicoya Peninsula): The dry season lingers early in May, but rains pick up—5-8 inches by month’s end. Temps hover in the upper 80s°F (30°C), with humidity creeping in as showers hit.
• Central Pacific (Manuel Antonio, Dominical, Uvita Jacó): Rain arrives in earnest—8-10 inches—often in afternoon bursts. Highs of 85-88°F (29-31°C) keep it steamy, and the jungle glows with moisture.
• Caribbean Coast (Puerto Viejo, Tortuguero): Wetter year-round, May brings 10-12 inches of rain, but it’s steadier, not torrential. Temps sit in the low 80s°F (27°C), warm and sticky.
• Central Valley (San José, Atenas): Mild and pleasant, with highs of 75-80°F (24-27°C). Rain’s light—4-6 inches—falling in short spurts, leaving sunny gaps.
• Highlands (Monteverde, Arenal): Cool and misty, with temps in the 60s°F (15-20°C). Rainfall climbs to 8-10 inches, feeding the cloud forests with a near-constant drizzle.

May’s weather is a pick-your-poison playlist—every region’s got its own beat.

What to Pack for May

May’s mix of sun and rain calls for a clever kit. Here’s what to bring:

• Lightweight rain jacket or poncho—your shield for afternoon downpours.
• Quick-dry clothes—breathable tees, shorts, and pants that laugh at humidity.
• Waterproof hiking shoes—muddy trails need traction.
• Swimsuit—hot springs and beaches are still calling.
• Bug spray—mosquitoes love the wet season’s start.
• Hat and sunglasses—for morning sun or Caribbean rays.
• Small umbrella—handy for Central Valley strolls.

Pack for a jungle jaunt and a beach break—May’s got both in spades.

Best Things to Do in May

Rain’s a spark, not a stopper. Here’s what thrives this month:

• Surf the Pacific (Nosara, Tamarindo): Wet-season swells kick off—perfect for wave-riders of all levels.
• Hike Monteverde’s Cloud Forest: The mist and light rain turn it into a dreamy trek—hit the canopy bridges.
• Relax in Hot Springs (Arenal): Soak in thermal pools as rain taps the jungle roof—pure zen.
• Beach Day on the Caribbean: Puerto Viejo’s calmer seas invite swimming and snorkeling between showers.
• Waterfall Quest: Rain boosts La Fortuna and Nauyaca Falls—bring a waterproof camera.

Mornings are your launchpad—plan adventures early, then unwind as the rain rolls in.

Unique Wildlife Experiences in May

May’s rains stir Costa Rica’s wild side into action. Here’s what to seek:

• Turtle Nesting (Tortuguero): Green turtles start nesting late May—night tours catch the magic.
• Sloths & Monkeys (Manuel Antonio): Wet jungles buzz with capuchins, howlers, and sleepy sloths.
• Whale Watching (Central Pacific): Humpback whales migrate through—spot them off Uvita or Dominical.

Travel Tips for May

A few smart moves make May a breeze:

• Book Early for Surf Spots: Pacific waves draw a niche crowd—secure Nosara or Tamarindo ahead.
• 4x4 Ready: Wet roads can get slick—rent a four-wheel-drive for rural hops.

• Check Openings: Some Pacific lodges close early May—confirm your stay.
• Lean Into the Rain: A poncho and a grin beat a canceled plan—May’s beauty is its fresh start.
