Conditions at La Selva in August
August: Tropical Swell Watch
August remains in the summer lull, but the tropical Atlantic starts to stir. Average swell height is around 4ft (1.2m) with an average period of 6.4s. The dominant directions are still ENE at 56% and E at 36%, though a slight increase in NE at 5% and NNE at 1% hints at the autumn transition ahead. Most waves are in the small, fun-sized range, but the occasional distant tropical cyclone can send in longer-period easterly swell to break the monotony.
Wind conditions are similar to July: E and ENE trades account for over 70% of observations, with ideal offshore winds only 30% of the time. Water temperature climbs to its annual peak of 28.9°C, and rainfall increases to 4.70mm per day with more afternoon thunderstorms. La Selva remains in summer sleep until the Atlantic hurricane season starts sending more organised swell in the coming months.
