The Lowdown
Alright crew, Rusty here. Let’s break it down.
First up, there’s a decent pulse of south-southeast groundswell coming in, but the window for clean waves is tight. Water temp is about 64°F, which is pretty normal for the time of year, nothing to write home about.
The standout is Thursday morning, August 13th at Guarita. We’re looking at 6ft of SSE swell with a 14-second period. That’s proper groundswell, and the combined energy is strong at 1186. The wind is light and offshore from the southwest, so those waves are going to be glassy and clean. It’s a reef break, advanced only, but for the experienced crew, this is the best session of the whole forecast. The water temp is a touch warmer than average, but nothing extreme.
Monday morning, August 17th, is another one to mark. Swell is a bit bigger at 8ft from the east-northeast, with a 9-second period. The combined energy is hefty at 1516. The wind is glassy from the south-southwest—just a slight air—so it’ll be clean. Again, this is for advanced surfers only; 8ft is a lot of power, and it’s a reef. The energy is strong, so expect some grunt.
After that, things go downhill. From Tuesday afternoon, August 18th, through to Saturday morning, August 22nd, the surf is mostly small, weak, or blown out. The wind swings around and gets onshore or cross-onshore, making for choppy, poor conditions. There’s a solid three-day stretch there where you’re better off doing something else.
Sunday morning, August 23rd, shows a bit of a pulse again—7ft of S swell with a 12-second period and combined energy at 1384. The wind is light cross-shore, so it’s not perfect, but it’s surfable. The spot is inconsistent, so don’t count on it.
The second week is a mixed bag. Monday morning, August 24th, has a 7ft SSE swell with a 13-second period, light cross-off wind, and combined energy of 1242. Clean conditions for the experienced. After that, the energy drops off and the wind gets messy again. The rest of the period into August 27th is mostly small, weak, and with poor wind. A lot of the combined energy readings are in the low hundreds, just not enough to get excited about.
Overall, the first week has a couple of golden windows, especially Thursday morning and Monday morning. The second week is pretty flat. If you can get out on those two mornings, you’ll be in for a treat. Otherwise, it’s a waiting game.
Rusty.

Information about the Guarita Surf forecast
The above surf forecast table for Guarita provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Guarita can be found by selecting the local surf guide option on the grey menu. Our Guarita surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Guarita) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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 Guarita 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
