Alright folks, Rusty here. We’ve got a mixed bag coming up for Trespassers over the next couple of weeks, but there are definitely a few windows to get excited about. Hang on, because it’s going to be a ride.
The water temp is sitting pretty average for this time of year, nothing unusual to report. That first solid session we’re looking at is Saturday the 5th. Early morning, the wind is gonna be blowing offshore out of the east at 12 mph, cleaning up a solid 5 ft swell from the SSW. The period is a juicy 17 seconds, so there’s serious groundswell energy in the water (1454). This is excellent for experienced surfers, and with that offshore breeze, the reef should be firing. Be aware, it’s also "fairly consistent" here, and crowds are "sometimes" a thing, so you might have some company. Sunday the 6th morning looks fun too with a smaller 3 ft set, but that easterly cross-offshore keeps it clean.
Now, mark your calendars for Wednesday the 8th of July. The morning session is a standout. It’s glassy, dead calm, with a solid 6 ft SSW groundswell from 17 seconds. The energy is pumping at 2113. For an advanced spot like Trespassers, this is a proper call. You’ll want your wits about you.
After that we get a bit of a lull. There’s a good, clean little window on the morning of Thursday the 9th with a 4 ft swell and cross-offshore breeze, and the evening goes glassy. But from Friday the 10th through the 12th, it’s pretty much all onshore junk. Strong winds, messy conditions, you might as well sleep in.
There is a size spike coming for the 13th of July with swell pushing up over 8 ft from the SSW, but the wind is mostly on it or cross-on, so the quality takes a big hit. It’s really only for the die-hard experts who don’t mind a fight. The 14th is basically a write-off with strong winds.
The real light at the end of the tunnel is the morning of Thursday the 16th of July. The wind swings to a light northerly, leaving it glassy with 5 ft of clean SSW swell at 15 seconds. Energy is moderate (818) but the conditions will be spot on. It won’t be as powerful as the 8th, but for a clean, fun session with no wind, it's a gem.
Keep it salty.

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.
