Conditions at Airport in July
July: Peak Size, Peak Intensity
July is the heart of the dry season and delivers the largest average surf of the year at 7ft (2.2m). The period remains a deep 14.4s, meaning powerful, organized groundswell. Direction stats show SSW (35.2%) and S (33.3%) almost even, with SSE at 9.0% and SW almost absent at 1.1%. This is pure Southern Ocean groundswell aimed straight at the island chain. The bigger 6-8ft (2-2.5m) sets are thick, fast and heavy, and with ideal wind at 46%, the month offers plenty of raw power but a lower percentage of perfectly clean sessions.
Wind is overwhelmingly from the ESE (59.7%) and SE (29.7%), continuing to blow offshore. However, a large portion of that flow sits in the 20-30kph range, limiting the truly ideal-wind percentage. When the trades ease into the 10-20kph zone, Airport gets hollow, grinding and world-class. Air temperatures are the coolest of the year at 23.5°C, water drops to 27.1°C, and precipitation is just 1.09mm/day.
