Alright mates, Rusty here. Let’s break down the next few weeks for Trestles (Uppers).

The water is about average for the season, so nothing out of the ordinary there.

The start of the period, Sunday the 5th, is a no-go. The wind is blowing cross-on at 6 mph, and the waves are tiny at 3 ft from the SSW. The combined energy is moderate (467), but it’s just poor conditions.

From Monday the 6th to Wednesday the 8th, we see a slight improvement. The swell picks up to around 3 ft, still from the SSW, with a long period of 16-18 seconds. The energy is moderate to strong (530-856). The wind is still on or cross-on, but on Monday morning there’s a chance of a clean-up with light winds. The long period makes for better wave shape, but the onshore wind keeps it from being pristine.

The best window is Tuesday morning, the 7th of July. The swell is 4 ft from the SSW, with an 18-second period, and the combined energy is strong (856). The wind is light and on, which is a big plus. For a point-reef break like this, that long-period groundswell will wrap in and give you some clean, lined-up waves. This is the standout of the whole forecast.

From Thursday the 9th onward, it’s a struggle. The swell drops, the wind turns southerly and cross-on, and the energy fades. There’s a long gap of several days with poor to marginal surf. The 14th and 15th of July are flat, with 1 ft swell and weak energy (198). Not worth the drive.

Toward the end of the window, on the 16th of July, there’s a small pulse of 3 ft from the west, but with a short 9-second period, it’s going to be weak and messy. The 17th and 19th of July have a little more period, but the wind is still cross-on.

So, the only real beacon in this forecast is Tuesday morning, the 7th of July. The rest is a lot of waiting for something that doesn’t fully materialize. Forecasts change, and it’s usually not this quiet for long.

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.
