The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s brewing for the Port Isaac stretch.
Straight up, I gotta be honest with you – this 16-day run is looking grim. We’ve got a big fat gap of nothing worthwhile for the first week and a half. The first real sniff of anything comes on the 2nd of August, but even then it’s not exactly firing. From now until then, every single session is rated as poor surf conditions. The combined wave energy barely cracks three digits, and when it does, the wind is all wrong. You’re looking at a solid 10-day stretch with no real surf on offer.
Now, the only time it gets a pulse is around Sunday the 2nd of August. On the Sunday morning, we’ve got a 5ft swell from the WNW, but the period is a short 6 seconds, so it’s gonna be a bit mushy and disorganised. The combined energy climbs to 200 (moderate wave energy), but the wind is a gentle cross-onshore, so it’ll be a bit choppy. The spot is Port Isaac, which is a beginner-friendly break that’s fairly exposed to the WNW swell. It’s fairly consistent here, but expect crowds – it says “sometimes,” so you won’t be alone.
The water temperature is about average for the time of year, nothing unusual.
For the rest of the window, forget it. The swell is tiny, the wind is onshore, and the scores are all zeros. On the 7th of August, we get a clean offshore wind from the S, but the swell is only 1ft – not enough to push you around.
So, what’s the call? The only standout, if you can call it that, is Sunday morning the 2nd of August at Port Isaac. It’s not going to be epic, but it’s the best of a bad bunch. For a beginner, the 5ft swell might be a bit much, but for an intermediate, it’s doable. Just keep your expectations low.
Rusty out.

Information about the Port Isaac Surf forecast
The above surf forecast table for Port Isaac provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Port Isaac can be found by selecting the local surf guide option on the grey menu. Our Port Isaac 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 (Port Isaac) 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 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.
