Alright, let’s put it in feet and miles, but the story’s the same.

Truth is, Port Isaac is looking like a total dud for the next 16 days. There’s no good surf to be found, so don’t bother paddling out just yet.

From now through the rest of the 16-day window, it’s mostly flat and weak. The first time you see any real size is Saturday the 18th of July, but it comes with problems.

Friday the 3rd starts with a glimmer – a clean, 4ft west swell at 10 seconds, with a light cross-offshore breeze from the SW. The combined energy sits at a moderate 284, and the water’s way warmer than usual for this time of year at 63°. It’s a good size for beginners, and you might see a few others out. But by afternoon the wind turns west and ramps up, turning the surf into chop.

Saturday and Sunday drop off fast – we’re looking at 3ft and 2ft, with onshore winds and messy conditions. Combined energy falls well below 100. From Monday the 6th right through to Wednesday the 16th, it’s a long, bleak run of tiny, weak, or blown-out surf. A few mornings are clean, like Friday the 10th with glassy water, but the swell is a tiny 2ft. Even Tuesday and Wednesday the 14th and 15th have clean conditions with moderate offshore winds, but it’s still only 3ft – small and weak.

Finally, on Saturday the 18th of July, the swell bumps up to 5ft from the west-southwest, with a period of 9 seconds. The combined energy hits a moderate 400. But the wind is onshore and sideshore, so the quality is poor. That size is too much for beginners, and the chop makes it ugly even for the more experienced crew. Port Isaac (United Kingdom) is fairly exposed to a west-northwest swell, so this south-southwest direction isn’t ideal. With that strong wind and the beach-and-reef setup, it honestly looks better for kite surfers than paddle surfers.

So, there’s no standout day here. Don’t force it. The surf will come back around – it always does.

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.
