July: Smallest Surf of the Year
July is Rockaway-Manzanita's low point in the annual swell cycle. Average swell drops to 4-5ft (1.2-1.4m) with periods around 9.7s, meaning the waves are fun-sized at best.

Most energy is in the 3-5ft (1-1.5m) range, though 5-6ft (1.5-2m) sets are common on the better NW pulses.
Wind is the bigger story. Only 9% of the time do conditions qualify as ideal offshore. The summer marine layer and thermal trough drive NNW winds a massive 51% of the time, with the 20-30kph class well represented.
