Conditions at Pororoca in May
May: The Transition to Dry
May marks the beginning of the downward slide. Rain totals fall to 8.81 mm/day and river levels slowly drop, while trade winds strengthen their grip from the ENE (39.3%) and NE (27.3%), with east winds now contributing 14.2%. The majority of those winds remain in the 0-20kph range, but ideal offshore conditions again sit at 0%. The open-ocean swell charts stay completely blank - 0ft (0m) and 0.0s - so the only wave source is the weakening tidal bore. Water temp warms to 28.5°C. Spring tides can still produce a rideable wave, but the rides become shorter and more sectiony as the month progresses. Average air temperature is 25.8°C.
