The Lowdown

G’day, Rusty here. Let’s be straight with you about Trestrignel. It’s a sheltered beginner break, and the next 16 days are a real mixed bag, but honestly, the standout windows are few and far between.

We kick off Wednesday the 5th of August with some small, junky surf. A 5ft west swell is rolling in, but it’s getting torn apart by a 16 mph WNW cross-onshore wind. The combined energy is moderate at 202, but the waves are choppy and messy—poor conditions through the afternoon. The water’s sitting at 66°, about 2° warmer than normal, so it’s a touch warmer than average for this time of year.

Thursday the 6th doesn’t offer much relief. The swell drops off to 4ft with a short 6-second period, and the wind stays cross-onshore. The energy is weak (122), and the surf is poor. By Friday the 7th, it’s almost flat—1.0ft with a tiny 28 energy reading. Saturday the 8th is even smaller, but the E cross-off wind will clean things up a bit, so the surface looks nice, but there’s nothing to ride.

We have a gap of small, poor surf through the next week. The swell tries to pick up around Monday the 10th of August—3ft to 3ft from the WNW, but it’s still cross-onshore and choppy with moderate energy (103-116). Not worth paddling out. This pattern of ankle-biters and onshore slop continues through to Saturday the 15th.

Now, here’s the one true standout, but it’s a big one. On Monday the 17th of August, a serious pulse of swell arrives: a 13ft WNW groundswell with an 11-second period. The combined energy is massive at 3967. That’s a lot of power. However—and this is a huge however—the wind is a cross-onshore 12 mph from the WNW, so the surf will be choppy and messy. Because the swell is over 8ft, this is strictly for experts only. Beginners should stay well clear. This break is sheltered, and the swell direction matches the optimum NW, but the wind will hurt the quality. Monday afternoon is slightly smaller at 12ft, but still challenging.

Tuesday the 18th sees the swell dropping back to 5ft, energy down to 315, but the wind is still on it. The rest of the week fades into marginal, poor surf again. The long period (11 seconds) on Monday means better shaped waves, with longer gaps between sets at this beach, but the cross-onshore wind ruins the potential.

Truth is, if you’re looking for clean, rideable waves, Trestrignel doesn’t have a classic day in the next 16 days. The big Monday 17th event is the only real pulse, and it’s wind-affected. If you’re into kitesurfing, the strong wind and solid swell on the 17th might look more interesting than paddle surfing. For the rest, it’s a pretty blank run. Forecasts can change, but right now, it’s tough.

Rusty.

A general guide to surfing at Trestrignel can be found by selecting the local surf guide option on the grey menu.

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.
