Trespassers Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it.

We’ve got a solid, extended run of surf building on the back of a decent SSW groundswell, and the standout window is definitely the last week of August into the very start of September. The water temp is sitting at 59° right now, which is pretty much bang on average for this time of year, so no surprises there.

The first real action kicks off Sunday afternoon, 16 August, at Trespassers (reef, advanced) . It’s moderate offshore from the ESE with a 4ft SSW swell at 14 seconds. The combined energy is moderate at 553 – it’s a solid start, clean lines, and a bit of power. This is just the warm-up though.

Monday, 17 August, keeps the good vibes rolling. Morning has a 4ft SW groundswell with a very long 16-second period, still offshore from the ENE. The energy bumps to 609 Monday morning, and by Monday afternoon it’s even better: 4ft, same long-period SW, and a clean moderate offshore breeze pushing the energy up to 848. That’s the pick of the early week – long, pushy walls, very clean.

Tuesday 18 August starts to get tricky. The wind swings cross-offshore from the NNE, still clean but the tide might mess with the shape a bit. Swell drops slightly. Wednesday 19 August is a write-off – onshore winds, lumpy, poor conditions.

Thursday 20 August brings some size back but it’s cross-onshore and choppy – a real shame because there’s plenty of energy (1028 Thursday morning) behind a 4ft SW. Not surfable in a good way.

Friday 21 August, the swell is up to 5ft in the morning and 6ft by afternoon, both onshore from the west. Energy is very high (1442 and 1802), but the wind makes it a mess. For a spot like Trespassers, with those strong onshores and a beach-and-reef setup, honestly, this looks more interesting for the kite crew than paddle surfing. Same goes for Saturday 22 August and Sunday 23 August – size is there, but the cross-onshore wind just kills the quality.

Now, here’s where it gets good. After a pretty grim middle stretch, we get a nice reset. Thursday 27 August is a standout. Morning shows 6ft from the WSW with a long 16-second period, and the wind is a light cross-offshore breeze from the ENE. Energy is huge at 1752, and conditions are described as clean. This is expert territory – over 5ft, but glassy and lined up. For the experienced crew, this is the one to circle.

Friday 28 August keeps the swell solid – 7ft to 7ft, WSW to SW, still cross-offshore. A bit more wind, but still clean.

But the absolute highlight of the whole 16-day window is Saturday 29 August. First up, morning: 10ft of SW swell, cross-offshore from the ESE, energy at 2379 – that is strong. That’s big, powerful, and for experts only. Then, Saturday afternoon? Pure magic. The swell drops slightly to 8ft, but the wind goes glassy – literally, light air from the south. The combined energy is 4435, the highest reading of the whole forecast. This is a proper groundswell, so it’ll be walled up, but with those light 5 km/h winds and a 17-second period, you’ve got long, perfect lines on the reef. That’s your one true standout. Get on it.

After that, Sunday 30 August and Monday 31 August fade back into smaller, less favourable wind conditions.

So, overall pattern: Solid start, rough mid-period, then a banger finish from Thursday 27 August through Saturday 29 August. The only real standout is Saturday afternoon the 29th – glassy, 8ft, and full of energy. Don’t sleep on it.

Rusty out.
