The Lowdown

Alright, this is Rusty checking in, and we've got a look at the next 16 days. Honestly, it's a bit of a mixed bag with some long quiet spells, but there is a couple of windows that could get the heart pumping.

We kick things off at Guarita, a reef setup that's advanced territory. Right now, the water's sitting at 60°F, which is a good 4°F colder than what you'd expect for this time of year – so you'll definitely feel that chill. The first real chance to get in the water this week is Thursday morning, the 27th of August. We've got a 5ft swell rolling in from the SSE with a 13-second period, and the wind is a light NNE cross-shore. The combined energy is moderate at 969, but the call is marginal, so keep your expectations in check.

After that, things get pretty grim. We go through a long stretch of small, choppy, and often rainy conditions. Friday the 28th has a brief pulse of 6ft from the ENE, but it's a short-period 8-second wind swell, and the wind is messy. Saturday and Sunday are small and poor. Monday morning looks a bit bigger again at 7ft, but the wind is on it. Monday afternoon sees a bump in energy to 8ft, with a combined energy of 1170, but it's still a short-period wind swell. The wind is light, so it's cross-shore, but it's still a messy, raw swell. Tuesday the 1st of September is a drop-off, but the wind goes cross-off, so the few small waves will be clean.

The real standout, the one you want to circle on the calendar, is Thursday morning, the 3rd of September. It's a classic small window of opportunity. The swell drops to a clean 5ft from the S, with a 10-second period, and the wind is glassy – a light N breeze. That means zero wind chop. The combined energy is moderate at 480, but for a reef break, that glassy surface and a clean south swell is as good as it gets here. It's the best call of the entire 16-day run.

After that, it's a slow fade. The rest of the first week and into the second week is mostly small and poor again. There's a pulse of energy on Monday the 7th of September, with a 8ft ENE swell and a combined energy of 1240, but the wind is howling cross-off at 16 mph. It's clean, but it's a big, raw swell for a reef, and it's only for the experts. The following Tuesday morning the 8th has a 4ft ENE swell with clean cross-off wind, so it's a good, small, clean option if you're desperate.

Finally, on Friday the 11th of September, we see another late-season push. A 6ft SSE swell with a 13-second period, combined energy of 1073, and clean cross-off wind from the SW. That's a promising, long-range prospect, but it's over a week away, so keep your fingers crossed.

So, the standouts are clear: Thursday morning, the 3rd of September for the glassy, clean south swell, and the Friday morning, the 11th of September as a long-range, promising call. The rest is mostly a write-off.

Stay sharp.

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.
