The Lowdown

G’day, Rusty here. Let’s have a look at what’s coming up for Trespassers.

Right off the bat, it’s a bit of a slow start. The first few days are on the small side, but the real standout is hiding in the second week.

We kick off on Wednesday morning, July 15, with a clean 4.9ft SSW swell, but the wind is a light cross-shore, so it’s not glassy. The water temp is sitting around 59.4°, which is bang on average for this time of year, nothing unusual there. The energy is moderate (1001). Not a total write-off, but it’s marginal.

Thursday morning, July 16, looks a bit better. The swell drops slightly to 4.6ft, still from the SSW, but we get a clean cross-off breeze. It’s small, but the conditions are clean. The swell period is 15 seconds, so that’s a nice long groundswell, which usually means better shaped waves and longer waits between sets. The energy is moderate (807). This is the pick of the early days.

Friday morning, July 17, is similar – 4.3ft SSW with a clean cross-off breeze. Again, small but clean. Saturday morning, July 18, the swell drops to 2.9ft, and it’s clean, but honestly, it’s getting small. The rest of that weekend and into the early part of the following week is a write-off – poor winds, chop, and dropping swell. There’s a gap of a few days with nothing worth paddling out for.

Then things get interesting. On Thursday, July 23, the swell picks up to 5.6ft from the SW, but the wind is a messy cross-on from the WSW, so it’s choppy and ugly. The energy is strong (1416). Not the day for it.

But the real standout is Friday, July 24. That morning we get a solid 6.9ft SSW swell, with a 17-second period – that’s a very long groundswell, packing serious energy (2404). The wind is light and cross-off from the SE, so the surf should be clean and lined up. This is the best on offer in the whole outlook. At 6.9ft, it’s pushing into expert territory, so it’s not for the beginners. This is a reef break, and with that long period, it should handle the energy well. The crowds at Trespassers are sometimes a factor, so expect a few other keen surfers out there.

After that, it fades again. Saturday morning, July 25, drops to 4.6ft with cross-on wind, and from there it’s back to small, windy, and poor conditions through the end of the month.

So, the call is clear: hold out for Friday, July 24. That’s the one.

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.
