The Lowdown

Alright, Rusty here. Let’s have a look at what’s shaping up for the next few weeks.

Alright, first up, the outlook is a bit of a slow burner. There’s plenty of swell in the water, but the wind is going to mess with it for a good stretch. The first real surf worth talking about doesn’t kick in until Thursday the 30th of July. Before that, Tuesday and Wednesday are a write-off – Tuesday is seeing 7ft to 7ft of SW swell with a 15-second period, but a fresh cross-onshore breeze is just making a mess of it. Wednesday is no better, with a similar-sized swell and a cross-onshore wind that’s leaving it choppy and lumpy. Don’t even bother.

Thursday the 30th of July is where it gets interesting. Trespassers (reef break) will be waking up to a 4ft SSW swell, with a 13-second period. The real hero here is the wind – glassy, dead calm. The water is sitting at 59°, which is about average for this time of year, nothing weird going on. The combined energy is moderate at 494, so it’s not a powerhouse, but it’s clean and surfable. The swell direction is a solid match for the break’s preferred SSW. This is a small, clean, and fun day for the advanced crew. The swell is only 4ft, so it’s a nice size, not too big, not too small. It’s a reef break, so it’ll hold the shape well with that long period, giving you some proper lines. Keep in mind it can get crowded here sometimes, but the conditions are too good to ignore.

Friday the 31st of July drops off a bit. The swell is down to 3ft, and the wind is light and clean, but it’s small. It’s surfable, but nothing to get excited about.

Saturday the 1st of August – the swell picks up to 4ft with a very long 18-second period, but the wind is a moderate cross-shore, putting a chop on it. The combined energy is moderate (984). It’s messy, but there’s a lot of power there. It’s a "marginal" call.

Now, Sunday the 2nd of August is a standout. The morning sees a 7ft SW swell with a 16-second period and a cross-shore wind, giving a combined energy of 2944 (strong). The afternoon, though, is the pick. The swell jumps to 8ft from the SW, still a 16-second period, and the wind swings to a cross-offshore breeze, cleaning it right up. The energy is very strong at 5945. This is a big, powerful, clean swell. 8ft is pushing into expert territory, but for the advanced crew at Trespassers, this is a proper session. This is the best on offer in the whole forecast.

Monday the 3rd of August is still solid. The morning brings a 5ft SW swell with a 14-second period and a clean cross-offshore wind. The energy is moderate (975). It’s a very good day, but a step down from Sunday.

After that, the wave heights drop off through the week, dropping to 2ft by Wednesday the 5th, and then it gets small and windy again. There’s a potential blip on Saturday the 8th of August with 6ft of SW swell, but the wind is onshore, so it’s poor. Not worth it.

The second week is a mixed bag. Sunday the 9th of August has 5ft of clean swell but a fresh cross-off wind, so it’s clean but blown out. Monday the 10th of August sees a 7ft SW swell, but the wind is messy. Tuesday the 11th has 8ft of SW swell, but again, onshore wind. The biggest event in the second week is Wednesday the 12th of August – a 10ft SW swell with a 14-second period, but it’s a fresh cross-shore, and the combined energy is very strong at 3644. That kind of size and power is only for experts, and the wind is going to make it a battle. It’s more of a kite-surfing day than a paddle session.

So, to wrap it up: the real standout is Sunday afternoon, the 2nd of August at Trespassers. Get on that. Thursday the 30th is your clean, fun, smaller day. The rest is a waiting game.

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.
