The Lowdown

Alright folks, Rusty here. Let’s look at what’s coming up for Trespassers. This is a reef break that takes a south-southwest swell best, and it’s pretty exposed, so it can pick up a lot of energy. The water’s sitting at 59°, which is pretty normal for this time of year, so no shock to the system there.

Right now, we’re in a bit of a quiet spell. The first few days are a write-off. Monday and Tuesday the 27th and 28th of July are a mess with strong, onshore wind and lumpy, poor surf. You wouldn’t want to be out there. Even the swell is building, but the wind has it chopped up. Wednesday the 29th of July is just marginal, with a 7ft SSW swell and a cross-shore wind, but it’s a bit of a bumpy mess. The combined wave energy is high (2712), but with the wind and the chop, it’s not a good paddle.

Thursday the 30th of July morning actually cleans up nicely. The wind drops to a light cross-offshore breeze, and the swell is a clean 4ft from the SSW. The energy is moderate (492), and it’s described as clean. That’s a brief window of fun, small waves. Friday the 31st of July afternoon is looking glassy with a 2ft SSW swell. Small, but clean.

The first real standout, though, is shaping up for the week ahead. Look at Wednesday the 5th of August. The morning and afternoon are both looking clean with a glassy or cross-offshore wind. The swell is 4ft to 4ft from the SSW, with a very long period of 18 to 19 seconds. That’s proper groundswell, and for a reef like Trespassers, that’s a dream. The energy is moderate (940), and the conditions are tipped as very good. This is the pick of the early part of the forecast.

Then, for the experienced crew, the real gem comes on Friday the 7th of August. We’ve got clean, offshore winds all day, and a solid 5ft to 6ft SSW to SW swell with a period of 17 to 18 seconds. The wave energy is strong (1966), and the report says it’s excellent for experienced surfers. This is a proper session for the guys who know the reef. It’s a little bigger, so beginners might find it a handful, but for the rest of us, it’s a standout.

The forecast also shows a big spike on the 11th of August with an 12ft swell, but the wind is cross-onshore and lumpy, so that’s going to be a wild, messy beast. Not one for the paddle crew.

So, to wrap it up: the first week is mostly a washout, with a few clean windows on the 30th and 31st. The real quality is on the 5th and 7th of August. The 7th is the king of the run, with clean offshores and a solid, long-period swell. Get on it.

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.
