The Lowdown
Alright folks, Rusty here. Let’s look at what we’ve got coming down the line for Guarita. This is a reef setup, advanced only, and it needs an easterly swell direction to really line up. Right now, the pattern’s quiet to start, so don’t rush.
The first real opportunity for a paddle shows up on Monday the 14th. The swell stays modest, around 4ft from the south with a period of 9 seconds, but the wind turns light. Monday morning sees a light cross-off breeze, and by the afternoon it goes glassy with an ENE wind at just 3 mph. That’s clean surf—good shape potential for a reef break, and the combined energy sits at 420 (moderate). The water temp is about average for this time of year, nothing out of the ordinary.
The next standout window is Friday the 18th. Morning brings a 5ft swell from the north-east, period 7 seconds, and clean conditions with a light N breeze. The combined energy reads 378 (moderate). For this spot, that’s the best combo in the first week. It’s a little short-period, but on a reef that can still offer some fun, punchy little runners. Crowds can be a thing here sometimes, so keep an eye out.
Then things get interesting toward the end of the second week. Thursday the 24th has a 6ft SSE swell in the morning, 9 seconds, light N breeze—clean, with combined energy of 491 (moderate). But the real highlight is Friday the 25th. That morning shows a 5ft SSE swell with a 12-second period, a light offshore from the NNW at just 3 mph, and clean as a whistle. The combined energy hits 667 (strong). That’s proper groundswell—long period, good push, and the optimum direction aligns nicely with the east. This is the standout of the whole outlook. It’s best suited for expert surfers given the size and reef setup, and it’s a week and a half out, so take it with a little caution, but the signs are promising.
Overall, don’t bother with the first few days—nothing worth suiting up for. There’s a clean run Monday the 14th, then a quiet patch mid-week before the action picks up again. The absolute gem sits on Friday the 25th. Mark your calendar.
Stay stoked,
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.
