The Lowdown

G’day, Rusty here. Let’s have a look at the next stretch of waves for Trespassers. This is a reef setup, and it’s fairly consistent, but it’s not for the faint of heart – advanced surfers only. Right out of the gate, the water’s running at 58.1°F, which is about normal for this time of year, nothing weird going on there.

The opening weekend is a bit of a wait-and-see situation. Saturday the 1st has some swell – around 3.6ft to 4.6ft from the SSW with a long 17-18 second period. The energy is moderate (769 and 1159). But the wind is cross-shore out of the north at 15-16 mph, which is going to put a chop on it. It’s surfable for the crew who don’t mind a bit of texture, but it’s not the kind of day you’d call clean. Sunday is a write-off – the wind swings onshore and picks up to 19-22 mph, and the rain moves in. Poor conditions, so stay on the beach.

We’ve got a real dud stretch from Monday the 3rd through Wednesday the 5th. Monday’s got a bit more size – 5.9ft to 6.6ft – but it’s coming with a shorter 14-second period and a cross-onshore wind that’s going to make it choppy and lumpy. The energy is moderate at best (1602 and 1270). Not worth the paddle. Tuesday the 4th drops right off to a weak 3.3ft, and while Tuesday afternoon goes glassy, the swell is just too small to get excited about. Wednesday the 5th is even smaller – 2.3ft – but the afternoon turns clean with a light cross-offshore breeze. Still, you’d be scratching for anything.

Thursday the 6th remains small, but there’s a hint of life. Friday the 7th is where things start to wake up. We’ve got 5.2ft to 5.6ft of SSW swell, pushing in with a solid 19-second period. The energy jumps to strong (2273). The wind is cross-offshore from the NNE at 16-19 mph, which should keep it reasonably clean. This is a proper groundswell, and on a reef like Trespassers, that long period is going to make for some well-shaped lines. This is a standout for the first week. Just be aware, with that long period, it can sometimes wall up a bit, but on a reef it should be fine.

Saturday the 8th and Sunday the 9th are messy again – the wind goes cross and onshore, and the swell drops. Not worth your time.

Now, here’s the big one. Monday the 10th: the swell jumps to a solid 9.8ft from the southwest with an 18-19 second period. The energy is very strong (8162). But, and it’s a big but, the wind is cross-onshore and moderate, which is going to chop up what could be a epic day. The guidance is calling it poor surf conditions. It’s a lot of water moving, over 8.2ft, so this is strictly for experts. For most of us, this is a session to watch from the cliff, not paddle out into. Tuesday the 11th is still big – 7.9ft to 8.2ft – but the wind remains fresh and cross, so it’s going to be lumpy and hard to handle.

Wednesday the 12th is a mixed bag. The morning looks better, with 7.2ft from the SSW and a 17-second period, and the wind goes cross-offshore from the SSE. It’s still big and powerful, but the surf quality looks cleaner. But the afternoon falls apart with rain and a strong cross-shore wind. Thursday the 13th is a step down in size but the wind turns onshore, so it’s not great.

Now, we’re getting into the second week, and this is where things calm down. The standout is Saturday the 15th. The swell is a friendly 3.9ft from the SSW, with a 15-16 second period. The energy is moderate (736 and 1076). The wind is light and cross-offshore from the SE – we’re talking glassy to clean conditions, and the guidance is saying “expect very good surf conditions.” This is the pick of the bunch for the whole forecast. It’s a long-range call, so we can’t be 100% sure, but it’s looking like a proper day out with clean, lined-up waves on the reef. The crowd factor is listed as ‘sometimes’, so you won’t have it completely to yourself, but it won’t be a zoo either.

Sunday the 16th is a smaller echo of that – 2.3ft to 3.0ft – with a light offshore in the morning. It’s worth a look if you’re keen, but the swell is fading fast. There’s a long gap with nothing from the 8th to the 9th, and again after the 12th, so you need to pick your days.

Overall, for the next 16 days, your two best bets are Friday the 7th for a proper sized groundswell, and Saturday the 15th for

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.
