Conditions at Kohala Lighthouse in July
July: Flat, Windy and Low on Options
July is the heart of the summer doldrums at Kohala Lighthouse. The average period drops to its lowest of the year at 8.4s, and the swell window is all but monopolized by east trade wind energy: E delivers 64.7% of all swell and ENE another 29.9%, while the north quadrant - the directions that actually work at this spot - virtually disappears. The slight silver lining is that the east swell still holds some size, with 34.3% of all events in the 1.5-2m (5-6.5ft) range, but it is steep, short-period, and hitting the north-facing coast at the wrong angle. The wind rose is a brutal read: ENE and E trades together account for 96.4% of all wind, and ideal surf wind is 0%. With water temp up at 25.9°C and air temp at 22.1°C, the conditions are tropical and tempting, but the ocean is mostly a churning, cross-shore mess. If you find a rare window where the trades back off, you are just as well off driving to a south-facing break.
