Conditions at Spiders in August
August: Trapped in the Same Pattern
August looks nearly identical to July from a surf standpoint. Average wave heights sit at 5ft (1.6m), average period at 8.2s, and NNW again accounts for 93.8 percent of the swell energy. NW makes up a meager 3.2 percent, and there is no meaningful W or WNW component. To get Spiders really going, we need a direction sweep to the west, but the North Atlantic subtropical high is doing its summer job and keeping swell-generating storms far away. Ideal wind percentages edge up to 40 percent, and morning easterly breezes can clean things up before the NNW trade takes over. Expect hot 29C air, almost zero rain, and 18.1C water. It is a good time for a swim or a small-wave foamie session, not for chasing serious size.
