Conditions at Caldera in July
July: Consistent Long-Period SSW, Still Small
July continues the long-period SSW signal with an average period of 14.2s. A full 75.8% of the directional spectrum comes from SSW, and adding SW (9.7%) and S (12.7%) means over 98% of all swell approaches from the southern half of the compass, which is excellent exposure for Caldera. The catch remains the same: only around 0.8% of the total is in the 2-3ft (0.5-1m) range, and the average height is about 1ft (0.3m). The wind pattern is slightly better than May and June, with offshore NNE/NE/ENE/E flow at about 25%, but onshore S/SSW/SW influences are still strong enough to keep the surface bumpy during the day. Precipitation eases a bit to 4.06mm/day, air temperatures average 26.9°C, and water temperature holds at 29.3°C. A high-tide, high-volume longboard will be your best friend this month.
