Conditions at Playa Junquillal in July
July: The Crown Jewel of the Calendar
July is statistically the best month to score quality surf at Junquillal. The combination of consistent SSW/SW groundswell and offshore trades peaks, with ideal wind conditions hitting 79% of the time, the highest of any month. Swell remains strongly aligned, with SSW at 79.8% and SW at 7.6%, while average height holds at 1.5m (5ft) and average period stays solid at 13.5s. Wave heights are concentrated in the fun-to-pumping band: over half the wave rose sits in the 1-1.5m (3-5ft) range, and another substantial share pushes into 1.5-2m (5-6.5ft).
Trade winds build through the NE/ENE axis and, crucially, blow offshore across the exposed beach, grooming the long-period Southern Hemisphere swell. Rainfall drops slightly to 5.05mm/day, air temperature averages 27.3°C, and water temperature is a warm 29.0°C. July is the month when you can reliably paddle out to clean, lined-up surf with warm water and long-period swell multiple days in a row. It does not get much better than this on a WSW-facing Costa Rican beach.
