Jaco Beach Weather Patterns

Jaco Beach is located on the central Pacific coast of Costa Rica. As a result of its subtropical climate, Jaco is characterized by warm weather throughout the year.

• Temperatures: Nightly lows rarely dip below the mid-70s, while daytime highs can reach the mid-upper 90s (°F).
• Green Season (May – November): Afternoon rain showers are typical. September and October are the rainiest months. The rainforests are vibrant and lush during this time.
• Dry Season (December – April): Rainfall is uncommon. Days are consistently sunny, hot, and dry.

Packing for Adventure: Expert Recommendations

Whether you plan on relaxing at the beach, hiking through the rainforests, or navigating a UTV through muddy trails, dressing properly is a safety requirement.

1. Beach Days & Water Sports

For lounging by the pool or sunning on the sand, standard swimwear is sufficient. However, if you are tackling active water sports, consider the following:

• Surfing & Rafting: Wear a sporty swimsuit or rash guard that stays in place.
• Footwear: Water shoes or old tennis shoes are essential for rafting adventures.
• Fishing: For fishing charters, bring a brimmed hat and a loose-fitting long-sleeved shirt for sun protection.
• Essentials: High SPF waterproof sunscreen and UV-protection sunglasses are non-negotiable.

2. Jungle Adventures & ATV Gear

Jaco offers world-class access to the rainforest. Whether you are on a canopy zipline or driving an ATV, safety gear starts with your clothing.

The "Must-Haves" for Jungle Tours:

• Footwear: Sturdy, closed-toed shoes (Hiking boots or sneakers). Flip-flops are often prohibited on these tours.
• Clothing: Long pants (Chinos, cargo pants, or jeans) to protect legs from engine heat, branches, and rocks.
• Colors: Darker clothes are better as you will get dirty (mud and dust).

3. Dinner & Evening Attire

Jaco maintains a "Pura Vida" vibe even at night. Most bars, clubs, and cafes have relaxed dress codes.

• Men: Khaki pants/shorts and polos or short-sleeved button-downs with loafers or clean sneakers. Sleeveless tanks are often not accepted in nicer establishments.
• Women: Summer dresses, skirts, and sandals.
• The Rule: "Business Casual" is the safest bet for fine dining.

Final Tip: Temperatures in San Jose (SJO Airport) are significantly cooler than the coast. Always pack a light jacket or sweater for your arrival and departure flights.
