Alright, Rusty here again, looking at the same forecast through a different lens.
It’s a tough stretch, no way around it. The long-range outlook is a real grind, with no proper green light days. The swell is tiny, the wind is a persistent cross-off from the ENE or NE, and it’s just not shaping up for anything worth paddling out for.
China Walls is the only spot in the picture, and it’s a classic reef set-up that needs the right direction to work. The optimum is a south swell, and we do see some pulses from the SSW and S, but they’re weak and the wind just doesn’t let up. The water temperature is roughly 80°, which is about average for this time of year.
Friday July 3rd through Monday July 6th: The swell is a joke. We’re looking at 2 ft to 3 ft from the SSW and S, with periods that bounce around between 15 and 21 seconds. The energy is low to moderate. The wind is a fresh breeze at 18 – 25 mph, which is cross-off. It’s clean, but the surf is basically flat and “poor.” There’s nothing here to get excited about.
Tuesday July 7th through Thursday July 16th: The story doesn’t change much. Small, weak swell continues, with heights from 1 ft to 3 ft. The energy values are still low to moderate. The wind stays a fresh breeze, 12 – 22 mph. The wave comments are all “poor” or “marginal,” and the scores are zip. There might be a little bump in energy around July 14th from the west, but it’s still only 3 ft and the wind doesn’t favor it. This is a long, quiet period.
Friday July 17th and Saturday July 18th: The final two days of the outlook. Same story. 2 ft to 2 ft from the S and SSW, period around 18 seconds. Energy is moderate. The wind is still a fresh breeze. It’s just more of the same “poor” conditions.
So, to sum it up: there are no standout days, no real windows of opportunity. The wind is too strong and the swell is too small and inconsistent. The set-up looks more interesting for kite surfing than paddle surfing, honestly.
Forget it for now, keep your gear in the car and wait for a change.

Further information to help with frequently asked questions about our surf forecast for China Walls may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
