The Lowdown
Alright, let's cut through it. Halfpoint/Fullpoint is looking at a rough 16-day stretch. The first week is pretty much a bust. The wind is howling from the east-northeast, cross-shore and strong, just turning the ocean into a lumpy, messy chop. The swell energy is moderate (1049 to 1273), but it's all short-period, wind-slop. Water temp is about 80°F, totally normal for this time of year, but you won't care about that when you're getting blown off your board.
Starting Friday, July 24th, you’ve got a solid 6-7ft of short-period ENE swell, but with 25 mph cross-winds, it’s a total mess. This nasty pattern hangs tough until Monday, July 28th. The first crack comes on Tuesday afternoon, July 28th. The wind shifts to a cross-offshore from the north-northeast at 22 mph, cleaning it up a touch. You’re looking at a solid 7-8ft of east swell with a 13-second period (that's a long-period groundswell), and the energy jumps to 2165. It’s only a 2/10 on the call, but it’s the best you’ll see in this bad spell. It’ll be a battle to get out.
The one real highlight is Wednesday morning, July 29th. Clean, strong 10ft of NE groundswell (11-second period), and the wind goes light offshore from the west-northwest at just 6 mph – pure glass. The swell energy is pumping at 2744. But here’s the catch: that’s too big for this break. 10ft with that much juice is strictly for experts. The forecast even says it’s oversized. So it’s a clear standout, but only for the crew on big-wave guns.
After that, it’s back to the grind. Thursday the 30th and Friday the 31st are more of the same: strong cross-winds and lumpy surf, with energy dropping into the weak-to-moderate range (489 to 901). The second week from August 1st onward is a sad story. It’s the same pattern – strong ENE cross-winds chopping up waist-to-chest-high waves. Energy stays low, mostly under 1000. There’s a tiny window on August 7th with a 2ft SSW groundswell from a 20-second period, but it’s onshore with storms around. Not worth the wetsuit.
So the bottom line: over 16 days, only one window – Wednesday morning, July 29th – and that’s for experts only. The rest is a long, blank run of bad wind and chopped-out surf. It’s a normal trade wind pattern for this area, but it doesn’t make it any easier to take.

Further information to help with frequently asked questions about our surf forecast for Halfpoint/Fullpoint 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.
