Conditions at Playa Junquillal in August
August: Powerful and Consistent
August continues the peak-season formula, with SSW swell at 77.3% and SW at 14.8%, leaving the beach in direct line of long-period, southwesterly groundswell. The average swell height remains 1.5m (5ft), the average period is 13.3s, and there is a large share of 1.5-2m (5-6.5ft) waves in the SSW/SW fields. Ideal offshore wind conditions hold at 67%, though the wind rose also shows more light E/SE flow than midsummer. This means morning glass is common, and the trade winds still groom the swell during much of the day.
Weather conditions stay tropical: rainfall averages 6.36mm/day, air temperature is 27.2°C, and water temperature reaches 29.2°C. August can produce some of the biggest, best-organized southwest windows of the year, especially when Southern Ocean storm tracks align. The main caveat is rain-squall activity, but between showers Junquillal is often working at a high level with powerful, rippable surf.
