The Lowdown
Alright crew, Rusty here. We’re looking at Guarita, a reef setup that’s advanced-only, exposed to the open ocean. Water temp is 62°F, which is about a degree cooler than average for this time of year—nothing crazy, just a little autumn chill.
The first real chance comes early on Thursday, September 3rd. Clean, cross-off breeze from the NW at 3 mph. Swell is a solid 5ft from the SE with an 11-second period. The combined energy is moderate at 474. That morning session is the pick for the start of the window. The afternoon goes marginal with a cross-shore wind.
Friday and Saturday, September 4th and 5th, are a total loss. Swell drops, wind goes onshore. Poor, weak waves.
Sunday, September 6th, has size but the wind is howling at 16 mph from the SW. Morning is a mess, but the afternoon has a 7ft south swell with a strong 1257 energy reading. The wind is still cross-off, so it’s clean but bumpy. That’s big and only for experts.
Now, the real gem. Monday, September 7th, morning. Glassy conditions with a 3 mph wind from the ENE. Swell is a clean 6ft from the SSE with a 9-second period. Energy is a solid 535. Expect very good surf. That’s the best call of the whole 16 days.
Tuesday, September 8th, fades. Skip it.
Wednesday, September 9th, morning brings a clean cross-off from the north at 6 mph, with 6ft of ENE swell. Energy is 697. A good morning, but the direction isn’t the optimum for the reef.
Thursday, September 10th, is small and ordinary.
Friday, September 11th through Saturday, September 12th, is a junk zone of onshore wind and weak swell.
Then, Sunday, September 13th, morning. The big one. 8ft of south swell with a 9-second period. Combined energy is a massive 1658. Wind is a light 6 mph from the SW, cross-off, and clean. This is excellent surf for experienced surfers, but over 8ft on a reef is expert-only. If you’re not solid, do not even think about it.
Monday, September 14th, morning is still good with a clean 5ft from the south, but the afternoon wind ruins it.
Tuesday, September 15th, morning is glassy again with a 3 mph NNW wind and 4ft of south swell. A nice, clean, smaller day.
Wednesday, September 16th, is small and fading with a long 14-second period swell that is too straight. Thursday, September 17th, has a massive 17-second period groundswell, but the wind is a fresh 22 mph cross-shore. A lumpy mess. Friday, September 18th, still has some long-period energy but it’s cross-shore and bumpy.
The standouts: Monday morning, September 7th, for the glassy, clean 6ft SSE swell. And Sunday morning, September 13th, for the biggest, most powerful swell of the window, but it’s a beast for the brave only.
Rusty, out.

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.
