Conditions at Ofir in May

May: Summer's Edges

May marks the shift toward the summer regime. Average swell height drops to 1.7m (5.5ft) and the average period falls to 9.8 seconds. The swell direction actually remains very favourable - NW (26.9%), WNW (21.3%), NNW (22.4%) and W (10.8%) - but the energy is shorter-period and less powerful. Most waves now fall in the 1-2m (3-6ft) category, and the surf becomes more susceptible to wind.

The wind is the limiting factor. Ideal conditions occur just 27% of the time, with the NNW wind blowing 27.3% of the time and NW adding another 11.9%. That persistent northwesterly flow keeps most days bumpy and cross-onshore. Look for offshore E/ENE/ESE/SE winds early in the day, or for a brief mid-month easing of the Atlantic high to produce a window of fun, rippable waves. Air temperatures average 15.7°C, water temperature reaches 15.7°C, and rainfall eases to 2.52mm/day.
