Alright, Rusty here. Let’s get into it, folks. We’ve only got one spot on the menu this time, but it’s a solid little reef break that’s gonna dish up some clean waves if you time it right.

We’re looking at Trespassers, a fairly exposed reef that loves a solid SSW pulse. The water’s sitting at 60°, which is about average for this time of year, so nothing wild on the temp front. The opening act kicks off Sunday afternoon, July 5. We’ve got a moderate 5ft SSW groundswell rolling in with a long 16-second period. That long period means proper shaped waves with plenty of energy – the combined energy is sitting at 1042 (moderate wave energy). The wind is a clean offshore from the ESE at 12 mph, so you’re looking at glassy, lined-up faces. This is the pick of the bunch right here. It’s an advanced reef break, so it’s not for the grommets, but if you’ve got the skills, it’s game on.

Monday the 6th eases back a bit. Morning has a clean 3ft SSW swell at 14 seconds with a gentle offshore from the ENE at 9 mph. Waves are clean and manageable, good for a longboard or a fun fish. The afternoon drops to 3ft, still clean with a light ESE breeze.

Tuesday the 7th is a repeat of that 3ft in the morning, but with a bit more breeze at 12 mph from the ENE, still offshore though. By the afternoon, the swell nudges up to 4ft from the SW with a 15-second period. Wind stays offshore, making for some nice long lines.

Then comes Wednesday the 8th – the swell jumps. Morning sees 6ft from the SSW with an 18-second period, and the energy bumps up to 1837 (strong wave energy). The wind is cross-offshore from the ENE at 9 mph, so the waves will be a bit more wind-affected but still clean. By the afternoon, it’s 5ft with a lighter 6 mph cross-offshore. This is a solid, powerful swell, but the wind might just put a bit of texture on it.

Thursday the 9th is smaller again, 3ft in the morning with light NNE winds. The afternoon goes to absolute rubbish with rain showers and a cross-shore wind, so skip that session.

Friday the 10th and Saturday the 11th are write-offs. Strong onshore and cross-onshore winds, lumpy and choppy conditions. Not worth paddling out. Sunday the 12th is worse – a risk of thunderstorms, and the wind is screaming onshore at 25 mph. The swell gets to 6ft in the morning, but it’s a blown-out mess. By the afternoon, it’s a massive 8ft SW swell with a 16-second period (combined energy of 4287, which is very strong), but it’s cross-onshore at 22 mph. That’s big and messy – only for the hardcore or the kites.

The start of the following week, Monday the 13th, is for experts only. We’ve got an 12ft SSW swell (energy of 9214 – very strong) and onshore winds at 28 mph. That’s dangerous and ugly.

Things start to clean up again Tuesday the 14th. Morning has a 5ft SW swell at 16 seconds with light cross-shore winds. It’s got some energy (1800), but the wind direction isn’t perfect. The afternoon drops a touch to 5ft but with a longer 19-second period, though the cross-onshore wind spoils it.

Wednesday the 15th is back to smaller, cleaner swell. 5 to 5ft SSW groundswell with very light winds. It’s marginal for quality, but at least you won’t get blown off your board.

The real hidden gem is Thursday the 16th. The morning is glassy – dead flat wind from the north at 3 mph – with a clean 4ft SSW swell at 15 seconds. That’s the kind of session you dream about. The afternoon gets a bit of a cross-onshore breeze, but the morning will be magic.

After that, from Friday the 17th through the end of the forecast, it’s pretty grim. Strong winds, lumpy conditions, and onshore slop. There’s a brief window on Saturday the 18th with a 6ft SW swell and light cross-shore wind, but the wind picks up again in the afternoon. The final couple of days, the 19th and 20th of July, are a total write-off with gale-force winds.

So, to sum it up: the standout is Sunday afternoon, July 5 – clean 5ft SSW groundswell with offshore wind. That’s your best bet. The glassy Thursday morning, the 16th, is another dark horse for a sneaky, clean session. Everything else in between is either blown out, too big for comfort, or just not worth the paddle.

Stay safe out there.

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.
