Alright mate, let’s talk about the only wave in the house – Trespassers.
The next couple of weeks are a bit of a mixed bag here. We kick things off with small, clean waves, but then the wind turns nasty for a solid stretch. The best of it is all up front.
Monday 6th July afternoon sees a modest 3ft SSW swell at 14 seconds rolling in. It’s not big, but with an easterly breeze going offshore, the surface will be glassy. The wave energy is moderate at 233, and the water is a normal 60°F for this time of year, nothing weird. It’s surfable and clean, but nothing to write home about.
Tuesday 7th July is where we get the standout. The morning has 3ft SSW swell at a beefy 16 seconds – proper groundswell – and by the afternoon it bumps to 4ft from the SW. The wind stays offshore from the ENE all day, and the combined energy climbs to 544. This is the pick of the forecast: clean, building swell, and that long period will make for some nice, lined-up waves. A good day to be in the water.
From Wednesday 8th July, it gets tricky. The swell jumps to 6ft Wednesday morning, but the wind goes cross-offshore, so it’s still clean. That 18-second period is very long – this will be a proper groundswell, but it might break a bit too straight at Trespassers, which is a reef setup, so it could still work. The afternoon gets a solid 5ft cross-off and clean, with a score that suggests excellent conditions for experienced surfers. The combined energy hits 1371 – solid moderate energy.
Then it all goes south. From Thursday 9th July right through to Tuesday 15th July, the wind either goes cross, cross-on, or onshore, and the swell gets messy or just too big with poor conditions. The weekend of the 11th and 12th sees 7ft to 8ft swells, but it’s blown out, lumpy, and not worth it for a paddle. For a week, the setup looks way more interesting for kite surfing than paddle surfing.
There’s a flicker of hope on Thursday 16th July morning. The swell drops to 4ft from the SSW, period 16 seconds, and a light cross-offshore breeze from the NNE cleans it right up. Combined energy is 801, and conditions look very good. But that’s the only bright spot in the second week.
After that, from Friday 17th July onwards, it’s mostly poor again: strong winds, cross-chop, and blown-out conditions through to the end of the window on Tuesday 21st July.
So, bottom line: Tuesday 7th July is the day to circle. Offshore wind, clean, building groundswell. Get out there early.

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.
