The Lowdown
Hey, Rusty again. Let’s get real—Siesta’s in a major slump. We’re looking at a full 16-day stretch with nothing worth talking about. From Tuesday the 25th of August all the way through to Wednesday the 9th of September, it’s flat or near-flat. That’s over two weeks of no real surf.
First few days are just a blank. Winds are messy—cross-onshore, onshore, a quick glassy morning on the 26th—but with zero swell energy, it’s just clean, flat water. Thursday the 27th afternoon shows a 1ft bump from the SSE, weak 4-second period (energy of 3). That’s not a wave. Friday the 28th has similar knee-high dribble, 0.7ft from the S, again super short period and low energy (1). Mornings are clean with light cross-offshore breeze, but barely rideable.
Weekend and into next week? Same story. Some clean mornings with cross-off winds (Sunday the 30th, Monday the 31st), but the swell stays at zero or barely registers. All energy values are low—weak stuff. When we hit September, there’s a risk of thunderstorms on the 3rd and 4th with stronger wind, but still no swell.
The closest to anything is Sunday the 6th of September morning. Glassy calm, 3 mph northerly, and a 0.7ft SSE swell. Period’s still 4 seconds, energy of 2. You might find a little bump on a log, but honestly, it’s not worth the drive.
Siesta’s exposed and likes swell from the SSW, but there’s no groundswell coming. It’s a beach/pier spot, inconsistent anyway, and right now it’s dead flat. Water temp’s about average for the time of year, nothing to note.
For a spot that’s already inconsistent, a long flat spell like this is pretty normal. Forecasts can turn, but for now, leave the boards home. Those afternoons with moderate cross-onshore wind and no waves are better for kite surfing.
Keep an eye out, but don’t expect much.
Rusty.

Information about the Siesta Surf forecast
The above surf forecast table for Siesta provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Siesta can be found by selecting the local surf guide option on the grey menu. Our Siesta 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 (Siesta) 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 Siesta 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.
