Costa Rica September — the vivid blue waters of Rio Celeste in Guatuso, one of the world's most striking natural phenomena

Best time to visit Costa Rica without the crowds

When to visit Costa Rica for fewer tourists — quieter sites, more authentic local atmosphere, and less pressure on transport and restaurants.

Best month

September

The wettest month on the Pacific — but the Caribbean coast enters its mini-dry season, and prices are at their lowest.

Cheapest month to visit Costa Rica by a clear margin: budget airlines, rock-bottom accommodation rates, and tours at reduced prices — the same country at a fraction of high-season cost

Caribbean coast (Puerto Viejo de Talamanca, Cahuita National Park) enters its own mini-dry season in September–October: while the Pacific drowns, the Caribbean enjoys better weather, calmer seas, and excellent reef snorkelling

Tortuguero turtle nesting continues through September — the late-season nesting is often less crowded with visitors; combine with a Caribbean dry-season beach extension

All months ranked — Without crowds

September

Best match

The wettest month on the Pacific — but the Caribbean coast enters its mini-dry season, and prices are at their lowest.

#1 for without crowds

July

Best match

Humpback whales arrive off the Pacific coast and sea turtles begin nesting at Tortuguero.

#2 for without crowds

October

Best match

Still the wet season on the Pacific, but whale watching peaks and the Caribbean coast is at its driest.

#3 for without crowds

June

Best match

Quietest month of the year — budget prices, almost no other tourists, and the rainforest at its most dramatic.

#4 for without crowds

May

Best match

Green season opens — prices drop 30–50%, Pacific surf improves, and the lush transformation begins.

#5 for without crowds

August

Best match

Green season in full swing — whale watching continues, turtles peak at Tortuguero, and the jungle is impossibly lush.

#6 for without crowds

November

Strong option

The transition month — Pacific rains ease significantly and the dry season approach brings improving conditions.

#7 for without crowds

April

Worth considering

Pacific coast transitioning — still largely dry, Holy Week brings Costa Ricans to the beach en masse.

#8 for without crowds

March

Worth considering

Hot, dry Pacific coast with spring break arrivals — excellent conditions but prices stay high.

#9 for without crowds

February

Worth considering

The driest month on the Pacific — and the Monteverde Music Festival makes the cloud forest worth the trip.

#10 for without crowds

December

Worth considering

Dry season returns to the Pacific — Christmas week is the single most crowded and expensive period in Costa Rica.

#11 for without crowds

January

Worth considering

Pacific coast at its absolute driest — Guanacaste beaches are perfect, but expect peak crowds and prices.

#12 for without crowds
