Conditions at Altura in July
July: Peak Summer Flatness and Dominant NNW Wind
July is the middle of the summer lull at Altura. Average swell is around 1-2ft (0.5m) with the lowest mean period of the year at 4.4s. SE is the leading useful swell direction at 16.2 percent, but almost all of it is below 3ft (1m) and too short to create genuine quality. W and WSW dominate the raw wave count at 19.9 and 15.9 percent respectively, yet they are aimed far too west to wrap consistently into this SSE-facing beach. The wind signature is classic midsummer: NNW at a commanding 36.2 percent and NW at 13.0 percent, but ideal surfing conditions only occur 17 percent of the time because the swell is so small and onshore S/SSW/SW flow still mixes in. Water temperature is warm at 21.5C, air averages 23.9C, and rain is nearly zero at 0.04 mm/day. Take the tiny morning windows and keep expectations low.
