The Lowdown
Alright folks, Rusty here. Let’s look at what Trespassers has cookin' for the next couple of weeks.
We’ve got some solid action right off the bat. Thursday the 16th morning is looking sweet. A 5ft SSW groundswell with a super long 15-second period, and the energy is pumping at a solid 807. The wind is a light NNE cross-off, keeping it glassy. The water temp is 59°, right about average for now. That is the standout session – clean, consistent, and that long period will give you some proper lines. It’s an advanced reef, so leave the foamies at home. Crowds can show up here sometimes, so don’t be surprised if you’ve got a few mates.
Friday the 17th morning keeps the run going with a similar 4ft SSW swell, still a 16-second period, and 853 energy. The wind is a touch stronger at 9 mph from the NNE, but still cross-off, so it’ll be another clean morning. The afternoon sees a slight shift to a 4ft SW swell, still clean but a bit more cross-shore.
Saturday the 18th drops off. Morning has 3ft SW swell with a 14-second period, energy down to 330. The wind is still cross-off, so it’s rideable, but the power is fading. The weekend gets weaker. Sunday the 19th through the middle of the next week looks pretty average. Swell dips below 3ft, periods are shorter, and the wind turns onshore or cross-shore. By the 23rd and 24th of July, we’ve got onshore wind from the WSW at 9-12 mph, totally messing up the shape. That’s a solid 5-day gap of poor conditions.
Now, hold onto your board. Around the 27th we get a big pulse. Monday the 27th morning shows a 8ft SW swell with a 14-second period, but the energy is a massive 4811. The wind is a strong 19 mph cross-shore, making it a lumpy, choppy mess. That’s big, powerful, and dirty – not a clean stand-out.
The second real stand-out is Tuesday the 28th morning. The swell drops slightly to 8ft from the WSW, still a 14-second period, with a massive 4407 energy. The key here is the wind shifts to a light 9 mph SSE cross-off, cleaning it right up. The report says it’s excellent for experienced surfers. This is your best bet in the second week, but it’s only for the experts – that’s a heavy wave at that size on a reef.
The end of the month has some hope. Thursday the 30th morning has a 5ft SSW swell with a 12-second period, energy at 1067, and clean cross-off wind. Then Friday the 31st morning looks even better with a 6ft SSW groundswell, 15-second period, 2177 energy, and clean cross-off wind. That’s a promising finish, but we’re talking about 2 weeks away, so keep an eye on it.
So, the plan: hit Thursday the 16th morning for the best all-round clean conditions. If you’re an expert, Tuesday the 28th morning is your big-wave playground. The rest of the time, you’ll be picking through scraps or waiting for the wind to play nice.
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.
