Conditions at Comporta in August

August: Summer Lull Continues

August stays in the summer lull, though there is a tiny uptick in average period to 9.1 seconds and ideal wind percentage to 27 percent. Swell size remains around 3ft (1.0m), and NW continues to dominate at 66 percent, with WNW adding 24 percent. The wave heights are very consistently small, with most observations sitting in the 1-4ft (0.3-1.2m) range. The wind is still mostly from the NNW at 39 percent, but the stronger thermal gradient of late summer often brings afternoon westerly sea breezes on top of the underlying northwesterly flow. Water temperature reaches 17.8°C, and air temperatures peak near 23.6°C. For surfers, August is about chasing the odd NW pulse and scoring clean glassy mornings before the wind gets up.
