The Lowdown
Alright, folks, Rusty here, and I’ve been through the numbers for Guarita (reef). It’s a bit of a waiting game, but there are a couple of sessions that’ll make it worth your while.
The surf starts off slow and a little choppy. The water is 60°, which is a bit colder than normal for this time of year. The first real highlight doesn't come until Saturday, August 29th. Saturday morning, you’ve got a glassy 4ft swell from the east with a moderate energy reading of 254. The wind is dead calm and glassy – perfect for a smooth session on the reef. Saturday afternoon stays clean with a light offshore breeze. Sunday, August 30th, is looking sweet too, with another glassy morning and a 4ft east swell. Perfect for a mellow, clean morning.
Then the quality drops away for a few days with onshore winds and messy surf. Thursday morning, September 3rd, gives you another shot with full glass and a 3ft southeast swell – small, but clean.
But the standout of the whole 16-day window is clearly Saturday, September 5th. Saturday morning brings a solid 7ft SSE swell with a 12-second period (that's a moderate-long period groundswell). The combined swell energy is a strong 1226. And the wind? Dead flat, glassy. That’s excellent surf for experienced surfers. Swell over 6ft is only for the crew that knows what they're doing. Those longer period SSE swells really wrap into a reef like Guarita, so expect some solid, well-shaped waves. Saturday afternoon drops to 6ft, still glassy, and a very good energy of 796 – still a great session.
After that, the surf gets a bit messy again with onshores and chop. Tuesday morning, September 8th, offers a clean 2ft wave if you’re keen for a paddle, but the real fire is that Saturday. The long-range Saturday (Sep 5th) is the one to lock in – a promising call for a serious reef session, but don't count it until you see the wind.
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.
