Conditions at Waimea in July
July: Summer Lull
July is the classic mid-summer lull. Average swell height remains at 5.6ft (1.7m), but the average period drops to 7.8s - the lowest of the year. ENE swell balloons to 64.5% of the total distribution, with E adding 27.8% and NE just 4.9%; every other direction is effectively absent. This is pure trade-wind swell: short, choppy, and typically less powerful.

Air temps are warm at 25.7°C, water temp warms to 25.9°C, and rain is light at 1.04mm/day. Unless a stray tropical disturbance sends an unusual swell northward, Waimea is small and surface-choppy in July.
