Conditions at Big Rock in May
May: Pre-Monsoon Pulse
May sees the surf size come alive: average height reaches 1.0m (3.3ft) and there is a healthy mix of 2-3ft (0.5-1m) and 3-5ft (1-1.5m) waves, an almost even split between the two. The period remains moderate at 7.8s, but the real story is wind: ideal offshore conditions now occur 47% of the time, with SSW/SW/WSW/W winds making up a significant share of the wind rose. The dominant swell direction is S/SSE, which is still not the ideal ENE/E window, but with offshore winds grooming the surface, Big Rock can produce clean, fun-sized surf on the better days. Air temperatures are hot - 31.6°C average with daily maxes around 43°C - and water temp peaks at 29.8°C. Precipitation increases to 1.68mm/day as pre-monsoon thunderstorms become more common. If you pick your windows, May is a legitimate shoulder-season month.
