August: Tropical Heat Meets Offshore Hopes
August remains in the summer lull, but the tropical clock is ticking. The average swell height is 0.8m (2-3ft) with a period of 12.3s, and S plus SSE swell still account for 98% of the wave observations. The main difference from June and July is that the ideal wind percentage climbs to 41%, and tropical cyclone activity in the eastern Pacific becomes a real wild card.
When a hurricane or tropical storm moves through the right corridor, Punta Arena can receive ESE or SE swell, which is far more favorable than the usual straight S lines. That can push waves into the 3-5ft (1-1.5m) range for a few days. The downside is that August is also the wettest month, with average precipitation of 2.30 mm/day, high humidity, and water temperatures near 29.9°C. If you can time a tropical swell with a light W or WNW offshore wind, the reward can be surprisingly fun.
