The Lowdown
Alright, crew, let’s break this down. The next couple of weeks are a proper test of patience. First part of the week is a fight against the onshores, and it’s not gonna be pretty. Lots of lumpy, choppy lines, not worth your energy.
We go through a flat spell around the 18th to the 21st. A few days of nothing to do but check your wax. But don’t get down, because the models are showing a serious pulse of south swell that’s got some life in it.
The first wave to jump on is the Saturday morning of the 22nd. Wind goes dead calm, and the swell picks up to 8ft from the south with a 10-second interval. All that energy’s got a clear path to Guarita (Northern Coast). It’s a reef break, and it holds up. The WNW offshore will keep it clean. This one’s for the experienced crew, but it’s firing. If you only get one session this week, make it this one.
If you’re keen for another, the 24th is looking like a good one too. Monday morning is glassy with a 7ft south-southeast groundswell, and the 25th has clean, cross-off conditions at 6ft. These are your long-period, groomed waves. The point will be working.
Further out, things get fickle. The 26th has size but messy winds. The 28th shows promise – a solid Friday morning with a clean cross-off, and the afternoon glassing off with 6ft. The 30th has a smaller, cleaner south swell on the Sunday morning. Just a heads-up, the long-range stuff is a bit of a lottery, so don’t set your alarm just yet.
Bottom line: get out there on the 22nd, and maybe again on the 24th. Water temp is around 62°F, about average for this time of year. Full wetsuit, booties if you're keen. Keep watching the charts, this one has some real potential.
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.
