The Lowdown
Alright, let me chew on this forecast for you. It's a rough one, boys and girls. We're looking at a long, dry spell of tiny, blown-out junk at Roaches Reef. Honestly, it's one of the most frustrating outlooks I’ve seen for this spot in a while.
The first real chance of a wave doesn't show up until Monday, July 27th. That’s a brutal 10-day gap of nothing but poor surf from the start. For the first week and a half, the swell is tiny, the wind is messy, or that cross-onshore chop is ruining any chance of a clean wave. It’s the kind of stretch that makes you want to hang up the wetsuit.
Now, let's talk about that Monday. The 27th of July morning is the one true standout. The combined energy of all swells directed here hits a moderate 214, with the swell height at 5 feet out of the west. The wind is a gentle WNW cross-offshore breeze, which will keep the surface glassy. The water temperature is 69°, which is a whole 9° warmer than normal for this time of year – that’s freakishly warm, very unusual. You’ll be in a spring suit at most. The swell period is a short 7 seconds, so it’s not going to be a powerful groundswell, but for a reef setup, it should still offer some fun, punchy little wedges. The whole spot is exposed to the swell, and the optimum direction is from the southwest, so that west swell is a decent match. It’s rated for intermediates, and since it’s fairly consistent and crowds are only sometimes an issue, you’ve got a real good chance of scoring a few clean ones to yourself that morning.
The only other blip on the radar is the morning of August 1st. We see a 3-foot west swell with a 73 combined energy, but it’s just surfable, nothing special. The wind is a clean cross-off from the north-northwest, so it’ll be tidy, but the energy is weak. It’s a consolation prize more than a mission.
So, bottom line: if you’re chasing waves, the only game in town is that Monday morning the 27th at Roaches Reef. Get out there early, because the afternoon turns to junk with a strong cross-shore wind. The rest of the long-range forecast is a washout, but keep an eye on it – it can’t stay this bad forever.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Roaches Reef 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.
