Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Trespassers over the next couple of weeks. It’s a bit of a wild ride, so hang on.
Right off the bat, we’ve got a Thursday morning window that’s genuinely worth paddling out for. The swell is a clean 3 ft from the SSW, and with a very long 15-second period, this is proper groundswell rolling in. The wind is a light breeze from the NNE, so it’s cross-offshore, keeping the surface clean. The wave energy is moderate (540), and the forecast is calling for good surf. This is a reef break for advanced surfers, and it’s fairly consistent, so it’ll be offering up some nice, lined-up waves. Keep in mind the water is about average for the time of year. Thursday afternoon sees a slight drop in size to 3 ft, but the period stretches to 18 seconds – that’s a very long period swell. The wind goes cross, so it’s still rideable, but the tide could be a factor.
Then, we hit a rough patch. From Friday morning all the way through to Tuesday, the wind is a mess. It’s mostly onshore or choppy cross-onshore, with strong breezes around 19-25 mph. The swell gets big, too, but it’s blown out. On Saturday the 11th, we’re looking at 8 ft on the afternoon, but it’s a strong cross-onshore mess with a combined energy of 1249, so just forget it. That’s kite-surfing territory, not paddle surfing. This windy, ugly trend continues for a solid 4 days.
Now, keep your eye on Wednesday the 15th. That’s the big comeback. The morning will see a clean 6 ft of SSW swell, and the wind will be a glassy offshore from the ESE. The wave energy is strong (1288), and the forecast is for very good surf. This is the standout of the whole period. The period is a solid 15 seconds, so it’s quality groundswell, and the offshore wind will make it an absolute dream for the advanced crew out here. The afternoon drops a bit to 5 ft, but it’s still clean.
Thursday the 16th and Friday the 17th keep the good times rolling. Both mornings have clean 4 ft and 4 ft swells with offshore winds. Friday afternoon, the wind goes completely glassy. That’s unreal. The swell is 4 ft from the SW, and it’s just glass, perfect conditions.
The weekend of the 18th and 19th gets choppy again with cross-shore winds, so that’s a skip. Then Monday the 20th into Tuesday the 21st, the swell gets huge again, hitting 8 ft, but it’s still cross-onshore and messy. The wave energy on Tuesday morning is massive (5073), but the wind is onshore, so it’s a raw, powerful, blown-out ocean. Not for the faint of heart, and not for beginners.
The very end of the forecast, on Thursday the 23rd and Friday the 24th, looks promising again. Thursday has a massive 10 ft SW swell, but with onshore wind, it’s marginal. However, Friday the 24th morning is glassy with a 6 ft SSW swell. That’s a 15-second period, clean as a whistle. It’s a week and a half away, so take it with a grain of salt, but if it holds, it’ll be another cracker.
Rusty.

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