The Lowdown
Alright, Rusty here. Let's be honest, the next couple of weeks are looking pretty grim for Port Isaac. The swell is tiny, the wind is mostly onshore or cross-onshore, and the wave energy is just pathetic. You're looking at days of marginal, weak surf that's barely worth a paddle. Things are so flat right now that there's a big gap in any real surf potential.
The first real pulse of noticeable energy doesn't show up until Sunday, July 26th. The swell jumps up to a messy 6ft from the W, with a period of 7 seconds. The combined energy is 358, which is a solid kick, but it's all locked in with a strong onshore wind from the NNW at 16 mph. That's going to be a bumpy, wind-chopped mess. Not surfable for a good time, honestly. This kind of wind and swell combo makes it look more interesting for kite surfing than paddle surfing.
The best chance for a decent wave comes on Monday, July 27th in the morning. The swell is still a clean 5ft from the WNW (6-second period), but the wind has switched to a north wind at 12 mph, blowing straight onshore. The energy is moderate at 153, but it's going to be a raw, onshore battle. It's not a standout by any stretch, just the least poor option on the table.
Towards the end of the run, Tuesday, August 4th, is a total write-off. More onshore wind and a weak 3ft swell. The water temperature is about average for the time of year, so nothing unusual there.
Honestly, I can't give you a single standout. The whole 16-day forecast is a bust. If you're desperate, the morning of July 27th might offer a few lumpy, blown-out waves, but it's not one for the memory bank. The rest is just a whole lot of nothing.
Stay patient, lads. It won't stay this poor forever.
Rusty.

A general guide to surfing at Port Isaac 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 Port Isaac 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.
