The Lowdown

Alright, let’s be real with you. The next couple of weeks are going to be a bit of a grind for waves around here. We’ve got a lot of small, messy surf on the horizon, but there are a couple of windows where it might just turn on.

Right off the bat, from Wednesday the 5th through the end of the first week, it’s a write-off. We’re looking at weak, short-period swell, mostly cross-onshore winds, and just a chopped-up mess. The swell energy is weak, in the 14 to 308 range, and honestly, you’d be better off doing something else. The combined energy is just too low to push any real shape through.

The days start to blur together with knee-high dribble and poor conditions. The wind is all over the place, but it’s never really helping. There might be a morning here or there with lighter breezes, but the swell is just too small to bother with. This is a good time to check the surf report, see the flatness, and go for a run instead.

We start to see a pulse of energy building around the 14th and 15th. The combined swell energy climbs into the 160 range on the Friday, then jumps to 443 and 495 on the Saturday morning. The swell is still not huge, around 6ft, and the period is a mediocre 9 seconds. The wind is light, but it’s still cross-onshore, so it’s going to be a little lumpy. Still, it’s the first time we’ve had some real push. It’s not going to be perfect, but it’s the best we’ve had in a while.

Then there’s a bit of a dip on the 16th and 17th, but the swell is still around the 4ft to 7ft mark. The energy is moderate, in the 173 to 478 range. The wind is cross-onshore again, so it won’t be glassy, but there will be some waves to fight for.

Now, for the standout. It’s all about Tuesday the 18th. The combined energy just explodes, hitting 1090 in the morning and 1255 in the afternoon. This is strong, powerful stuff. The swell is up to 8ft to 8ft, with a period of 10 seconds. That’s a proper groundswell. The problem is the wind. It’s a fresh breeze, cross-shore to cross-onshore, which will make it lumpy and challenging. This is not a day for beginners. At over 8ft, it’s expert territory, and with that wind, it’s going to be a battle. Honestly, with that wind and the size, this setup might be more interesting for the kite surfers than for us paddle surfers. It’s going to be a washing machine out there.

The 19th backs off a bit, with energy in the 269 to 329 range, but it’s still cross-onshore and choppy. The 20th brings a fresh offshore breeze which will clean things up, but the swell has dropped back down to 3ft, so it’s a trade-off.

So, what’s the call? The Saturday the 15th is your best bet for a manageable, if not perfect, surf. It’s the most rideable of the lot. The Tuesday the 18th is the biggest and most powerful, but it’s for experts only, and the wind will make it ugly. It’s promising, but it’s a long way out, so don’t book the day off work just yet.

Water temp is about average for this time of year, so a 3/2 or a 4/3 will be fine depending on how you run.

Keep an eye on the forecasts, and don't get too bummed about the flat spell. It never stays this poor for long.

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.
