Alright, Rusty here. Let’s break down what’s coming our way for Trespassers over the next couple of weeks.

Right out of the gate, we’ve got some solid-looking swell pushing in. Wednesday morning, July 8th, is looking prime with a 6ft SSW groundswell rolling in at 18 seconds. That’s some serious energy and the wind is a light cross-off from the ENE, keeping things clean. This is a reef setup for advanced surfers only, and with that size and long period, it’s going to be powerful and a bit tricky. The water temp is sitting at 60°, which is right about normal for this time of year. Conditions hold for the afternoon too, dropping a touch to 5ft but still very clean.

Thursday morning, July 9th, backs off a bit to 3ft from the SSW, still with a long 15-second period and light cross-off winds. It’s cleaner but smaller – a decent session for the seasoned surfer. That afternoon the wind shifts to a light cross-on from the NNW, and the waves drop to 3ft, making it a bit more marginal.

Now, here’s where it gets rough. From Friday, July 10th, all the way through to Tuesday, July 21st, we’re looking at a long, ugly run of onshore and cross-onshore winds, mostly from the W and WSW, picking up to 22-28 mph. The swell sticks around, with some days pushing over 7ft and even 10ft on Saturday the 11th, but the wind just destroys it. The energy levels get huge, but with that wind, it’s going to be a churned-up, messy, dangerous mess. This is not for paddling – this is kite-surfing territory if anything.

The standout window actually lands further out. Look at Wednesday, July 22nd. That morning we get a solid 8ft SW groundswell at 15 seconds, with a light cross-off from the SE, making for clean conditions for experienced surfers. The energy is massive. That afternoon turns glassy with a 8ft SW swell and no wind at all. That’s your best bet for a proper, clean session in the whole outlook. Thursday the 23rd drops back to 6ft with a cross-shore wind, so it’s still surfable but not as perfect.

So, to sum it up: the first few days have some clean, solid waves for the crew that can handle a heavy reef, but then we’re in for a long stretch of grotty, blown-out conditions before a real gem appears on the 22nd. Keep your eyes on that Wednesday.

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.
