Alright, Rusty here. Let’s talk about what we’ve got on the table for the next couple of weeks.

First up, we’re looking at Trestles (Uppers). It’s a reef and point setup, very consistent, and it’s exposed to the swell. The water temp is sitting at 69°F with an anomaly of about 3°F above normal, so it’s a touch warmer than usual for this time of year – not a crazy shift, but you’ll feel it. Don’t expect much for the start though. Saturday the 4th through to Friday the 11th is pretty much a write-off: marginal to poor surf, small SSW swell around 3ft to 4ft, and mostly cross-onshore breezes keeping things choppy and messy. The combined wave energy floats between 393 and 920 – moderate energy, but the quality just isn’t there because of wind and poor conditions.

There’s a long gap here with no real recommendation for well over a week. The real standout window pops up later. Check this: Saturday the 18th morning, we start to see a shift – slight offshore in the a.m. with a light cross-off wind from the North in the afternoon. Swell is 3ft from the southwest, at a nice 17 seconds period – that’s a proper long-period groundswell, bringing shape and punch. The combined swell energy sits around 482 to 488, and for the first time in a long while, the forecast calls for clean waves. The wind is light and glassy/offshore, so the lines should be clean and fun on the point. This is the best on offer. Don’t get too excited too early; it’s still a bit far out, so treat it as promising but not locked in just yet. After that, Sunday the 19th fades back into cross-onshore chop, so that Saturday window is your best bet. It’s likely to be busy – crowds are listed as always here, so I’d plan for a dawny or late session.

Right now, for the next couple of days, the water temp at Trestles (Uppers) is about 69°F, which is a touch warmer than normal for this time of year – you won’t need a thick suit. Through the middle of next week, it’s a flat, blown-out slog. No real hope until that Saturday the 18th.

Stay sharp, and keep an eye on that Saturday the 18th window. Might be worth burning some fuel for.

Information about the Trestles (Uppers) Surf forecast

The above surf forecast table for Trestles (Uppers) provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Trestles (Uppers) can be found by selecting the local surf guide option on the grey menu. Our Trestles (Uppers) 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 (Trestles (Uppers)) 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 Trestles (Uppers) 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.
