The Lowdown
Alright, Rusty here. Let’s break down what Guarita’s got cooking for the next couple of weeks. It’s a bit of a patchy run, but there’s some real nice windows if you time it right. First decent surf doesn’t roll in until Saturday the 12th, so you can pretty much write off Friday.
Saturday the 12th morning kicks things off proper. Water temp is about average for this time of year, nothin’ wild. You’ve got a clean 7ft swell from the south, cross-offshore breeze out of the southwest. That’s a strong combo – combined energy is 921, and the wind is giving it a clean face. This is the standout of the first week. This is a reef break, so it handles that south swell well. But 7ft is serious – that’s advanced territory, not for beginners. Crowds are possible, and the break is fairly consistent.
Sunday the 13th is smaller and a bit messy. Monday the 14th is a washout with onshore wind. Tuesday the 15th morning though – that’s a glassy little treat. Calm wind, a 4ft east swell, combined energy only 277, but it’s perfect for a longboard. Clean as a whistle.
Midweek gets chunky. Wednesday the 16th morning brings a 7ft south swell, moderate cross-shore wind, combined energy at 1151 – that’s strong, expert-only on that reef. Thursday the 17th morning has a 6ft south-southeast swell with a 13-second period – groundswell, long lines, combined energy of 1008. The reef will love that, but the wind is cross-shore and moderate, so it might be a little bumpy.
The weekend after that – Saturday the 19th and Sunday the 20th – is where it gets clean again. Both mornings are glassy. Saturday morning has a 5ft east-northeast swell, energy 406. Sunday morning is 5ft from the east, energy 282. Small, clean, fun on the reef. That’s your second standout window.
Second week gets quieter. Tuesday the 22nd morning offers a clean 4ft south swell with a 10-second period, light offshore from the north, combined energy of 404 – a nice little window. Wednesday the 23rd afternoon cleans up with a light offshore, but it’s only a 4ft swell. Thursday the 24th is flat and rainy. Friday the 25th has a fresh offshore from the west-southwest at 18 mph, with a 5ft south swell at 11 seconds – combined energy 524, clean but windy.
Last day on the books, Saturday the 26th morning, is glassy again – 4ft south-southeast swell, 10-second period, combined energy of 402. A nice, clean finish.
Best bets? That Saturday the 12th morning, and the glassy weekend on the 19th and 20th. Pick your windows and you’ll get some good ones.
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.
