Conditions at Cimaja in May
May: Size Up, Quality Down
May is when the Indian Ocean winter swell machine starts pumping, but Cimaja pays for it with persistent SE trades. Average swell climbs to 1.6m (5ft), average period reaches 14.0s, and the swell direction is nearly split between S at 47% and SSW at 46%, with a touch of SSE. Around 49% of waves are in the 1.5-2m (5-6.5ft) range and another 10% tip into the 2-2.5m (6-8ft) range. That is real groundswell. Ideal wind drops to 22%, and ESE/SE flow dominates the wind rose. The result is often a lumpy, onshore mess with occasional clean windows. If the trades break down for a day, May can pump; otherwise keep expectations in check. Air temperature averages 26.6°C, water temperature is 29.3°C, and rainfall dries out significantly to 5.8 mm/day.
