The Lowdown

Alright folks, Rusty here. Let’s have a proper look at what’s cooking at Guarita over the next couple of weeks.

Right off the bat, we’ve got a slow start. The first few days are a bit of a write-off – small, messy, weak energy. We’re looking at a bit of a frustrating wait for anything decent. The water temp is sitting at 62°, which is pretty much bang on average for this time of year, so no surprises there.

The first real sign of life shows up on Saturday, the 22nd of August. The morning session brings a clean 6 ft swell from the south, with a cross-offshore breeze. The combined energy is moderate at 621, and it’s rideable, but it’s still a bit marginal. It’s not the standout, but it’s a sign things are waking up.

Now, the one to really circle on the calendar is Monday, the 24th of August. This is the pick of the entire forecast. We’ve got a 7 ft groundswell from the SSE with a very long period of 14 seconds, and the morning is dead flat calm – glassy as a mirror. The combined energy is strong at 1861. This is proper, powerful, clean surf. Because of the size and the long period, this is one for the experienced crew only. Over 8 ft is expert territory, and this is close to that, so if you’re not confident, sit this one out. The direction is a touch from the east for the optimum, but the quality of the swell and the wind make it a true standout.

After that, things settle back down. The following days drop off in size and get chopped up by onshore winds. We get a small window on Sunday, the 30th of August morning with a 4 ft SE swell and light cross-shore wind, but it’s only marginal. Then, on Monday, the 31st of August, the swell bumps up to 8 ft again from the ENE, but it’s accompanied by a nasty cross-onshore wind and rain, making it a messy, onshore mess – more of a kite-surfing setup than a clean paddle session.

The first week of September looks pretty poor overall. The wind is consistently onshore or cross-onshore, and the swell is lumpy. There’s a small pulse of 5 ft to 6 ft south swell on the 2nd and 3rd of September, but the conditions are not clean.

So, to sum it up: the first two weeks are a slow burn with one absolute gem on Monday, August 24th. If you can get out that morning for the glassy, powerful SSE groundswell, that’s your winner. The rest of the period is largely one to watch from the beach or spend doing something else.

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.
