The Lowdown
G’day, I’m Rusty. Let’s talk about what’s happening at Guarita.
The first part of this 16-day run is pretty slow. Early on, the swell is small and short-period from the ENE, and the wind is mostly messy. Monday the 17th and Tuesday the 18th are largely marginal or poor, though Tuesday morning does have a glassy 1.2m swell—still weak and short. It’s not until the 23rd that things start looking up.
The standout session is Monday morning, 24th August. Guarita gets a solid 8ft S swell at 11 seconds, with clean cross-offshore winds from the WSW. The combined energy is strong at 2210, and the water temp is about average for this time of year at 62°F. This is excellent surf for experienced surfers—clean, powerful, and well-shaped. If you’re an advanced surfer, this is your window.
The second best is Sunday morning, 23rd August. A clean 5ft S swell at 11 seconds, with light cross-offshore winds and moderate energy at 540. Good quality, clean surf, but smaller than Monday.
There’s also a promising session on Thursday morning, 27th August: 6ft ENE swell, glassy conditions, and moderate energy at 648, worth a look if you’re around.
After that, the swell fades, and the last few days of August into early September are mostly marginal or poor, with only a brief window of clean 3ft E swell on Saturday morning, 29th August, but nothing special.
Overall, the best stretch is from the 23rd to the 27th, with the 24th being the pick of the bunch. The rest of the forecast is quiet or messy. Crowds are possible at Guarita—it’s a reef that can get busy sometimes. Consistency is fair, so don’t expect constant waves, but when it comes, it’s worth it.
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.
