The Lowdown
Alright, let's get into it. The next couple of weeks are looking a bit tricky, to be honest. There’s plenty of swell on the way, but the wind’s gonna be a fight for most of it. We’re looking at a bit of a slow start, then a few windows where things line up proper.
We kick things off right now on Wednesday the 9th. We’ve got a solid 6ft of WNW swell at Trestrignel, but it’s coming with a stiff 12 mph NW wind, straight onshore. It’s gonna be messy and blown out. Not worth your time. That afternoon the swell drops slightly to 5ft+ but the wind stays on it. Water temp is sitting at 65°F which is a touch warmer than average for this time of year, so you might get away with a thinner suit if you’re brave.
Thursday the 10th sees the swell back off to around 3ft. The wind swings SW and goes cross-off, which is a big improvement. It’s clean but pretty weak – just ordinary surf, not much push. Only a 135 combined energy, so it’s all a bit weak.
Friday the 11th gives us some more size, up to 5ft+ again, but the wind is cross-on from the west at 6-9 mph. That's a no-go for clean waves, just chop and bump. The energy is more moderate at 436, but it won't matter with that wind.
The weekend is much the same. Saturday, a bit of size then a 16 mph westerly punches it onshore. Sunday is similar vibes with 5ft+ on tap but the cross-on wind stays. It’s all just kind of messy. Not what we want.
Now, Monday the 14th is where things start to look up. Early morning we get a break. The wind drops right out to almost nothing, glassy conditions, and we still have a clean 3ft of WNW swell. It’s small, but it will be the best conditions we’ve seen for days. This is a real early-bird special. That afternoon, it goes a bit crumbly again.
Tuesday the 15th has a bit of a tease. A 9 mph ESE cross-off wind, clean, but the swell is tiny at 2ft with a long 12-second period. It’s pretty much flat, so don't get your hopes up.
But then, hold on to your board. Wednesday the 16th afternoon, this is the one that catches your eye. We’ve got a jump in swell to 6ft from the WNW, with a 10-second period. Combined energy is cranking at 643 – that’s strong, very strong for this spot. And the wind goes to a light 3 mph SW, which is cross-off and clean. This is the standout of the whole forecast. Expect good surf conditions. This will be the one to call in sick for.
Thursday and Friday, the 17th and 18th, look like a step back. The wind goes onshore and cross-onshore again, wrecking the 5-6ft of swell. Friday afternoon especially sees a long 15-second period but there’s no wind to help it, just lumpy onshore junk.
Now we move into the second week. Saturday the 19th has another interesting window. We get a 5ft WNW swell with a strong 12-second period, and the wind is a clean cross-off from the east at 9 mph. The combined energy is strong at 573. It’s a promising call, but it's far out, so treat it as a “maybe”. After that, the winds get strong from the NE and things get lumpy again. From the 20th to the 24th it's mostly cross-shore junk with moderate to fresh winds. The swell sticks around but the conditions just aren’t there.
Keep an eye on the 16th afternoon, and maybe get up early on the 14th. Otherwise, there might be a few more kite-surfing days than surfing days on the horizon.

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.
