The Lowdown

Alright, this is Rusty, and I gotta be straight with you – the next couple of weeks are looking pretty slow for Trestles (Lowers). The water is running at 75°F, which is way warmer than we usually see this time of year – a full 8°F warmer than normal.

We don't really have anything worthwhile to report until the 9th of August when things start to look a little more interesting. Up until then, it's a whole lot of nothing. From the 1st of August right through to the 8th, the swell is tiny, mostly under 2ft, with a bit of onshore breeze, and the call is consistently "poor surf conditions." Don't even bother waxing up.

The first real standout, and really the only one in the whole window, is the morning of the 9th of August. A long-period groundswell of 3ft from the SSW at 15 seconds starts to roll in. The combined energy climbs to 442 (moderate wave energy), and the wind is a light cross-onshore at 6 mph. It's not perfect, but it's the most promising we've got, and it's a good call for a crew that knows what they're doing. This is advanced territory, so leave the soft-tops at home.

The 15th of August, Saturday afternoon, has a marginal call with a 3ft SSW swell and a combined energy of 558 (moderate wave energy), but the wind is light cross-onshore, keeping it bumpy. It's a "maybe" for the more dedicated surfers, but nothing special.

The rest of the 16 days is just more of the same – small, weak, and uninviting. The swell stays under 3ft for the most part, and the wind is often onshore or cross-onshore, so the quality is just not there. The 12th through 14th see a bit of a lift in period, but the wind is a mess, especially with the 12 mph cross-onshore on the 16th. It's a long stretch of flat and poor conditions, so don't hold your breath.

Rusty.

Information about the Trestles (Lowers) Surf forecast

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