Alright folks, Rusty here. Let's have a look at what's on the table for Trestles (Uppers) over the next couple of weeks.

We've got a long haul ahead. The first week is going to be a real test of patience, with mostly poor conditions and only a handful of marginal windows. The good news is, it’s a very consistent reef and point break that handles swell well, so when the stars align, it can fire. Right now, the water is sitting at 69°, which is much warmer than normal for this time of year – a solid 4° above average, so the sting is off the water.

The run kicks off from Thursday the 2nd through to Saturday the 4th of July. The surf is small, around 2ft to 3ft from the SSW, but the wind is a killer. It's cross-onshore from the WNW and W, chopping things up real good. The combined swell energy is moderate, sitting between 430 and 505, but it doesn't matter when the surface is blown out. You're better off waiting.

Sunday the 5th and Monday the 6th of July are where it gets slightly interesting. Swell is still small at 2ft to 3ft, but the morning sessions see a shift to light onshore winds from the WSW. The period stretches out to a long 16–20 seconds, which is pure groundswell. This will put some real shape on the waves, especially for a point like Uppers. The combined energy bumps up a notch to 527 and then 651 by Monday afternoon. It’s still not a standout, but those light wind windows are your best chance for a clean, waist-high wave.

From Tuesday the 7th through to Thursday the 9th, the swell ticks up a fraction to 3ft–4ft, with energy climbing into the high 600s to 800s, which is moderate to strong. The wind is mostly light and onshore or cross-onshore from the SSW. The period stays long, 16–18 seconds. This is about the best we’ve got, but the scores are still marginal at best. It’s just not clean enough to call a highlight.

Then we hit a real flat spell. From Friday the 10th of July all the way through to Thursday the 17th of July, the swell drops right off. Heights are mostly 1ft to 3ft, with combined energy falling from 500 all the way down to 165. The wind is mostly cross-onshore, and conditions are consistently poor. There’s a glimmer on Wednesday the 15th afternoon where the wind goes light cross from the NW, but with only 1ft of swell, it's barely a ripple. This gap of over a week with nothing worthwhile is a tough stretch for the area.

So, for the whole 16-day outlook, there is no true standout session. If you’re desperate, keep an eye on the early mornings of Sunday the 5th, Monday the 6th, and Tuesday the 7th of July when the light offshore winds meet that long-period groundswell. For everyone else, I'd say save your energy and wait for the next weather pattern to roll in. The forecast can always change, but right now, it’s a waiting game.

Rusty.

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.
