If you are planning a vacation to Costa Rica’s Northwest Pacific beaches in July, you are not alone. Many travelers ask the same question before booking their trip: “What is the weather like in Guanacaste during the rainy season? I hear it rains a lot.”
The short answer is no, it does not rain a lot, especially when compared to other regions of Costa Rica. In fact, Guanacaste is Costa Rica’s driest province, and even during the so-called rainy season—officially from May through November—the weather is often ideal for beach vacations.
This article will help you understand what to realistically expect from the weather in Guanacaste’s Northwest Pacific beaches during the rainy season, including rainfall patterns, temperatures, daily rhythms, and why many experienced travelers actually prefer visiting at this time of year.
Understanding Costa Rica’s Rainy Season
Costa Rica has two main seasons:
- Dry Season: December through April
- Rainy Season (Green Season): May through November
The term “rainy season” can be misleading, especially for first-time visitors. Many people imagine constant rain, gray skies, and ruined travel plans. That image may apply to certain tropical regions—but not to Guanacaste.
Unlike the Caribbean side or the southern Pacific coast, Guanacaste receives significantly less rainfall due to its geography and climate patterns. The province lies in a rain shadow created by mountain ranges, which limits how much moisture reaches the region.
Why Guanacaste Is Different
Guanacaste’s Northwest Pacific beaches—including popular areas such as Tamarindo, Playa Flamingo, Playa Conchal, Playas del Coco, and Playa Hermosa—are known for:
- Dry tropical forests
- Open savannas
- Long stretches of golden sand
- Consistent sunshine
Even during the rainy season, Guanacaste often feels more like a sunny beach destination with occasional afternoon showers, rather than a rain-soaked jungle.
What the Weather Is Like in July
July is part of the rainy season, but it is also known for a phenomenon locals call “veranillo de San Juan”, or “little summer.” This is a brief mid-year period when rainfall decreases and sunshine dominates—even though it’s technically still the rainy season.
Morning Weather
- Mornings are typically sunny and bright
- Blue skies and warm tropical sunshine
- Ideal time for:
- Beach walks
- Swimming and snorkeling
- Surfing
- Boat tours
- Hiking and sightseeing
Most experienced travelers plan their activities early in the day to take full advantage of the sunshine.
Afternoon Thunderstorms: A Tropical Show
In the late afternoon, usually between 2:00 and 4:00 p.m., you may experience a brief tropical thunderstorm. These storms are:
- Short-lived
- Dramatic
- Refreshing
Rather than lasting all day, they often pass quickly, leaving the air cooler and the landscape greener.
Many visitors find these storms exciting to watch, especially from:
- A beachfront hotel balcony
- A restaurant overlooking the ocean
- A covered terrace with a cold drink in hand
The lightning can be spectacular—often described as nature’s fireworks, lighting up the sky much like a Fourth of July display.
Evenings and Nights
After the rain passes:
- Evenings are usually calm and pleasant
- Skies often clear again
- Temperatures cool slightly
This creates perfect conditions for:
- Outdoor dining
- Beach sunsets
- Evening walks
- Relaxing without the intense heat of midday
Hotels along the Northwest Pacific coast are well-equipped with air conditioning, but many travelers find that nighttime temperatures are comfortable enough without it.
Temperatures in Guanacaste During the Rainy Season
Guanacaste is warm year-round, but the rainy season brings a welcome balance.
Typical Temperatures
- Daytime highs: Around 80–88°F (27–31°C)
- Evenings: Mild and comfortable
- Nights: Pleasant, rarely cold
The brief afternoon showers help cool the air, making the heat more manageable compared to the intense dryness of the peak dry season.
Ocean Conditions
The Pacific Ocean remains warm throughout the year. During the rainy season:
- Water temperatures are ideal for swimming
- Surf conditions are often excellent
- Marine life is active
July is a great month for:
- Surfing
- Fishing
- Boat tours
- Dolphin and whale sightings (especially later in the season)
Advantages of Visiting During the Rainy Season
Many seasoned Costa Rica travelers intentionally choose the rainy season—and Guanacaste in particular—for several reasons:
1. Lush Green Landscapes
The rains transform the dry forests into vibrant green scenery. Hills, trees, and plains come alive, offering stunning photo opportunities.
2. Fewer Tourists
July has fewer crowds than peak season. Beaches feel more spacious, tours are less crowded, and popular destinations are more relaxed.
3. Better Prices
Hotels, vacation rentals, and tours often offer lower rates during the rainy season, making it an excellent time for budget-conscious travelers.
4. Authentic Experience
You experience Costa Rica as locals do—at a slower pace, with time to enjoy nature, sunsets, and spontaneous moments.
What to Pack for July in Guanacaste
Packing smart ensures you enjoy your trip regardless of brief showers.
Recommended items:
- Lightweight rain jacket or poncho
- Breathable clothing
- Sandals and water shoes
- Sunscreen (the sun is strong!)
- Hat and sunglasses
- Swimsuit (you’ll use it every day)
An umbrella is optional—most rain showers are short enough that you may not even need one.
Is the Rainy Season a Bad Time to Visit?
Absolutely not.
In fact, many visitors say they enjoyed Guanacaste more during the rainy season than during the dry season. The combination of sunshine, cooling rain, and fewer tourists creates a relaxed and enjoyable atmosphere.
If your goal is to:
- Relax on beautiful beaches
- Enjoy tropical weather without extreme heat
- Watch dramatic skies and sunsets
- Save money and avoid crowds
Then July is an excellent time to visit Guanacaste’s Northwest Pacific beaches.
