The Lowdown

G’day, it’s Rusty here. Gotta be straight with you: the next couple of weeks are looking pretty grim for a proper paddle at Trestrignel. We’ve got a long, flat spell ahead, so if you’re hanging for waves, you’re going to be waiting a while. The first decent pulse of energy doesn’t show up until August 24th, and even then, it’s a marginal call. For now, the ocean is mostly just a lake with a bit of chop on it.

Right now, through the rest of this week and into next, we’ve got tiny, weak swells. Wednesday the 12th has a little push of 2ft from the west at 10 seconds, and the energy is only 99 – that’s weak. The wind is light and cross-offshore in the morning, so it’ll be clean, but there’s just no power in the water. It’s a flat, glassy paddle at best. The following days stay in that 3ft to 3ft range with crossed-up winds and lumpy conditions. Not worth getting excited about.

The water temp is sitting at 66°, which is about 2° warmer than usual for this time of year. That’s a noticeable bump, but nothing crazy. It’ll feel okay without a hood.

We’ve got a long stretch of nothing here. The swell stays weak and the wind keeps messing things up. By the 17th, there’s a pulse of short-period 4ft from the northeast, but it’s only 5 seconds – that’s junk. It’s crossed-up and blown out, more like a washing machine than a wave. That setup looks a lot more interesting for kite surfing than for paddle surfing, to be honest.

The real event, if you can call it that, is on August 24th, Monday morning. That’s the first time we see some proper energy – 473 units of swell – with a 5ft west-northwest swell at 10 seconds. The wind is light and onshore, which is not ideal, but the size and power are there. It’s still only a marginal forecast, and the tide might be questionable. For a sheltered spot like Trestrignel, 5ft is a step up, but with that onshore wind, it’s going to be a bit messy. Still, it’s the best we’ve got in the whole window, so if you’re desperate, that’s your morning. The afternoon drops to 5ft with a bit less energy, same story.

So, bottom line: the next two weeks are mostly a dud. There’s one day – the 24th – that’s promising but not a sure thing. Keep your hopes in check, but don’t sell the board yet. Forecasts can change.

Rusty.

Information about the Trestrignel Surf forecast

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