The Lowdown

Alright, this is Rusty, and I’m looking at the local setup for the next couple of weeks. It’s a pretty quiet start, so don’t rush to grab your board just yet.

We’ve got one spot on the radar: Trespassers. It’s a pretty consistent reef break, but it’s an advanced wave, so it’s not for the faint-hearted. The water temp is sitting at 59°F, which is pretty much normal for this time of year, so no surprises there.

The opening days are a bit of a write-off. Sunday the 2nd and Monday the 3rd are just poor, with messy onshore winds and rain. Tuesday the 4th starts to look a little better, but still nothing to write home about—Tuesday afternoon sees a bit of glassy wind and a 3ft SSW swell, but it’s only a 1/10 score. Not worth the trip.

Wednesday the 5th and Thursday the 6th are small and weak, with swell under 3ft and energy in the 300-500 range. The winds are okay, but the waves just aren’t there. You’ll be bobbing around more than surfing.

Friday the 7th shows a bit of life—clean offshore winds from the NNE and a 6ft SW swell, with energy around 1580. The score is a 3/10, so it’s marginal at best. The wind is clean, but the swell quality is still a question mark.

Then we hit a big gap. Saturday the 8th through Wednesday the 12th is a total loss. Strong winds, lumpy, choppy, cross-onshore mess. That’s five days of nothing. Don’t bother.

Thursday the 13th is still rough, with an 8ft SW swell but a short period of 9 seconds and onshore wind. It’s a no-go.

Now, here’s the standout. Friday the 14th. This is the one. Friday morning kicks off with glassy conditions and a solid 10ft SSW swell. The energy is strong at 2882, but it’s the afternoon that’s the real gem. Friday afternoon: glassy, calm, with an 8ft SSW swell and a 19-second period. The combined energy is a massive 10525—that’s serious power. This is a true expert-level wave, and the conditions are exceptional. The score is an 8/10. This is the best surf on offer in the whole 16-day window. If you’re an advanced surfer, this is your moment.

Saturday the 15th and Sunday the 16th are still very good, with clean, glassy conditions and solid SSW swell in the 5ft to 7ft range, with long periods of 17-19 seconds. The energy is still high, but it’s a step down from Friday. Scores are 4/10, which is still a solid session.

Monday the 17th is a bit more onshore and choppy again, but still rideable if you’re keen.

To sum it up: the first week is a bust. The second week is where it’s at, with Friday 14th August being the absolute standout. That’s the day to clear your schedule. The rest is a lot of waiting and watching.

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.
