The Lowdown
G’day, Rusty here. Let’s be straight with you – the next couple of weeks are looking pretty flat and bleak for Trestrignel. There’s nothing rideable on the cards at all for the next 13 days, so don’t even bother waxing up yet. The water’s sitting at 67°, which is a touch warmer than usual for this time of year, so that’s something, but the swell just isn’t there.
The first week and a half is a write-off. We’ve got a mix of tiny, weak waves below 3 ft and a whole lot of onshore junk. The energy is mostly weak, with readings from 21 to 178 in the combined swell energy. The winds are mostly cross-onshore or choppy, and the period is short and messy. Honestly, it’s more of a kite-surfing wind farm than a surf spot.
We finally see a glimmer of life on the morning of the 27th. The wind goes glassy, and the swell jumps to 4 ft from the W with a period of 8 seconds. The combined energy is 177, which is moderate, but the waves will be very ordinary. It’s surfable, but you’ll be scratching for anything decent. The swell jumps again in the afternoon to 6 ft, but the wind turns light cross-onshore and the combo energy hits 497 – still not great, and the period is short. You could get a few, but it’s not worth getting excited about.
Now, here’s the standout – Friday the 28th, the morning session. The swell is pumping: 13 ft from the W, with a period of 12 seconds. That’s proper groundswell. The combined energy is a massive 3871 – strong to very strong. The wind is fresh offshore from the E at 19 mph, which will carve those waves clean. This is for experts only, no question – 13 ft is way over the 8 ft limit for everyone else. Long period at a sheltered spot like Trestrignel might get a bit walled, but it’s going to be heavy. This is the one to be on.
The afternoon of the 28th turns to junk, with 25 mph cross-onshore winds and messy conditions. The 29th has big swell – 13 ft and 12 ft – but the onshore winds kill it. Not worth the paddle.
So, in short: 13 days of nothing, a couple of ordinary ones on the 27th, and then one big, clean morning on the 28th for the brave. That’s your lot.
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.
