G’day, Rusty here, lookin’ at what’s comin’ for Thirroul over the next couple of weeks. Water temp is sittin’ around 65°, which is about average for this time of year, so nothin’ wild there.
Right off the bat, we’ve got a bit of a slow start. Friday the 10th is lookin’ messy – cross-shore wind and only marginal waves, not worth paddlin’ out for. Saturday the 11th morning is the first real chance to get wet. Clean with a light cross-off breeze, swell around 4ft out of the SE, period 9 seconds. Nothin’ huge, but it’ll be fun and clean. Energy is moderate (352). Come Sunday the 12th, the swell drops right off – tiny 2ft to 2ft with offshore winds, but it’s just too small to bother with. Monday the 13th and Tuesday the 14th are flat, with wave heights barely hittin’ 1ft. A real quiet patch.
Now, Wednesday the 15th gets interesting but not for the right reasons. Swell jumps to 7ft from the S, but it’s a short period of 8 seconds and the wind is a fresh cross-shore, making it lumpy and choppy. On the 15th afternoon, it gets even bigger – 10ft – but same story, messy cross-shore wind. This is more of a kite-surfing setup than a paddle session. Thursday the 16th stays big, around 8ft to 8ft from the SSE, period only 7 seconds, and still cross-shore wind. Big, crumbly, and average.
The standout of the whole outlook? Gotta be Sunday the 19th morning. Swell bumps up to 8ft from the ESE with a long period of 12 seconds, and the wind is a light cross-off breeze, so it’ll be clean. Combined energy is strong (1759). That’s a session for experienced surfers – the size is up there, but the conditions will be excellent. The only downside is crowds can be an issue at Thirroul sometimes, so get there early.
The next little highlight is Friday the 24th morning. Swell 5ft from the E, period 10 seconds, light cross-off wind, clean conditions. Energy is solid (873). A good, solid session for all skill levels. After that, Saturday the 25th morning is similar with 5ft from the ESE, light cross-off, clean again, but energy is a bit lower (431).
Overall, it’s a mixed bag. The first week is mostly flat or poor, but the second week has a couple of real gems, especially the 19th. Keep an eye on that one.

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