Conditions at Nine Palms in August
August: Peak Southern Swell and Tropical Moisture
August continues to pump serious S swell into Nine Palms. Average swell height holds at 3.9ft (1.2m) and the S direction accounts for 73% of the wave energy, supported by 20% from SSW and 6% from SSE-the biggest SSE contribution of the summer. The 3-5ft (0.9-1.5m) class is packed with 46.1% S energy, and 5-8ft (1.5-2.5m) waves become more common than in July, spread across S, SSW and SSE. This is classic hurricane-summer surf: powerful, steamy, and occasionally XL when a tropical system sends a 6.5ft (2m) pulse. Wind quality is still challenging at 40% ideal, with SSW, S, SSE and SE winds all sitting between 9 and 12%.
Precipitation jumps to 2.22mm/day, air temperature averages 29.0°C, and water temperature peaks at 29.9°C. The wet season is fully established, and surface conditions are frequently affected by shower activity, outflow boundaries and lingering onshore swells. Consistency is the trade-off: dedicated surfers can score excellent clean bombs if they time the tides and an offshore wind event, but the average day is more likely to be soft, rain-squashed and bumpy.
