Table - best surf conditions forecast for Port Isaac over the next 16 days.
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Honestly, I gotta be straight with you – this is a tough one. We’re looking at a pretty bleak stretch here. The first real surf on offer isn’t until July 10th, and even then, it’s pretty ordinary. The conditions are just not playing ball for most of the period.
The real kicker is the wind. For days on end, we’ve got howling onshore winds from the NW and NNW, just wrecking any chance of decent surf. The swell is small, mostly under 3 ft, and the period is short – we’re talking 6-8 seconds, so it’s weak, gutless stuff. The combined energy barely cracks 100 (moderate) for most of it, and often sits in the weak zone below that. There’s a bit of a bump around July 18th and 19th, with the swell trying to push to 4 ft from the W with a period of 9 seconds, giving us a moderate energy reading of 308 (moderate), but the wind is still onshore from the NW, making it a messy, blown-out affair. It’s frustrating, because that’s the best swell size we see, but it’s just not clean.
The only break in the clouds is the morning of July 10th at Port Isaac. It’s a beginner-friendly spot, and fairly exposed to the W. The swell is small at 3 ft from the W, but the wind is a light E breeze at 10 km/h, coming cross-offshore. That’s the cleanest wind we get all forecast. The water is a touch warmer than normal at 63°F with a anomaly of 3°F, which is a nice little bonus. The combined energy is 104 (moderate), so there’s a little bit of push. It’s not going to be firing, but it’s surfable. If you’re desperate to get wet, that’s your window. After that, we slide back into a long run of poor, wind-affected conditions right through to July 24th.
So, the standout is a single, fleeting moment on the morning of the 10th. It’s not going to be epic, but it’s the only chance for a clean ride. The rest of the period is a write-off for paddle surfing. Honestly, with the onshore slop and weak swell, the setup from the 18th onwards looks more interesting for kite surfing than pushing a surfboard through it.
Rusty.

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.
