Conditions at Tonel in July
July: Peak Summer Slump
July is generally the slowest month for quality surf at Tonel. The average swell height is 1.4m (4-5ft) and the average period drops to 8.2s, which is short-period windswell territory. Swell direction is split between NW at 43.9% and NNW at 46.5%, with WNW at only 5.1% and W virtually absent. This creates a lot of weak, sectiony lines that need a favouring wind to become fun. Unfortunately, wind is not on our side. Ideal offshore conditions from the E/NE quadrant sit at just 7%, and NNW winds are relentless at 68.2% of observations, with a large share blowing 30-50kph. This is the classic Iberian summer pattern, caused by the thermal low over Spain drawing a strong northerly jet along the coast. With air temps averaging 21.3°C and water at 18.3°C, the beach is beautiful, but for surfers it is mostly bumpy and blown out. Pick the rare lighter-wind windows or head to the margins of the bay for shelter.
