The Lowdown

Alright, let’s get into it. This is a tricky one, I’m not gonna lie. The next 16 days are looking pretty grim overall for Trespassers, with only a couple of windows that might get the heart beating a little faster. The first week is a write-off, so don’t bother checking the cam until we get into August.

The outlook starts with a long, frustrating gap. Nothing good on offer from Friday 24 July right through to the end of the month. We’ve got a mix of cross-on winds, choppy conditions, and just messy waves. The swell is there, but it’s blown out. On Tuesday 28 July, the combined energy is pumping at 2348 (moderate to strong), with a 6ft swell from the SW, but it’s a total mess with 25 km/h cross-on wind. That’s a kite session, not a paddle session.

Wednesday 29 July is a bit smaller at 6ft (SSW, 15s period) and the wind drops off, but it’s still a bit cross-on and the forecast is only marginal. The water temp is about 59°, which is pretty normal for this time of year.

Now, Thursday 30 July morning is the first real glimmer of hope. It’s a small window, but it’s glassy. The swell is 4ft from the SW (13s period), combined energy 406 (moderate). The wind is glassy from the S at 5 km/h. That’s clean, but it’s small. For a break like Trespassers, a reef setup, that period is decent, but it’s not a standout.

The real standout here, and the only one I’d get excited about, is Monday 3 August. Check this out: morning shows a 5ft swell from the SSW with a 16s period, bringing 1230 combined energy (strong). Wind is 10 km/h from the ENE, which is cross-off and clean. The afternoon is even better for the wind – 5ft from the SSW (15s), 886 combined energy (moderate), and offshore wind from the E at 10 km/h. That’s clean, lined-up, and for a reef break like Trespassers, that long period groundswell is going to set up some real nice lines. The morning of Monday 3 August is the best on offer. It’s a week away, so keep an eye on it, but that’s the one.

The rest of the second week is a bit of a mixed bag. Saturday 1 August afternoon has a solid 7ft swell from the SSW (20s period!), but it’s got a cross-on wind and is only rated marginal. That’s a big, powerful, very long period swell – best for the reef, but the wind might ruin it. Sunday 2 August is similar, around 6-6ft, but still cross-on. From Tuesday 4 August onward, the swell drops off and the wind goes offshore, but the waves get small and weak. That’s a clean but tiny end to the run.

If you’re a beginner, that 6ft on Tuesday 28 July or the 7ft on Saturday 1 August is too big for you, and the conditions are messy anyway. Focus on the glassy morning of Thursday 30 July for a small, clean session, or keep your fingers crossed for Monday 3 August.

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.
