Conditions at Ohama in July
July: Summer Peak, Longer Period But Southerly Bias
July keeps the average height at 4.5ft (1.3m), but the period improves to 8.0s, signaling a more organized ocean as typhoon season starts rumbling to the south. SSW at 20% and SW at 19% are the dominant swell directions, with S at 14%, so much of the energy arrives from the southwest of the exposure, a bit off-angle but capable of pushing wrap around the coast. The E/ESE/SE/SSE window totals about 37%, so there are still fun summer pulses, especially under morning NW/NNW breezes. Winds are dominated by WSW at 32% and SW at 14%, keeping ideal wind at 28% but usually confined to early windows. Water temperature reaches 24.9°C, air averages 24.9°C, and with 7.9mm/day of rain, keep the rain jacket nearby.
