The Lowdown
Right then, let’s have a proper look at what’s on offer for Port Isaac over the next couple of weeks.
To be honest, it’s a pretty grim outlook for paddle surfing. The whole 16-day window is a write-off. There’s not a single session that’s worth getting excited about. The forecast is packed with onshore and cross-onshore winds, and the swell is mostly small and weak. The first real chance of any surf comes on Sunday the 26th of July, but even then, the morning sees a 6ft swell from the WNW with a short period of 7 seconds, hammered by a fresh 19 mph cross-onshore wind. The combined energy is moderate at best (293), but the wind is going to ruin it.
The best conditions for clean surf actually show up on Tuesday the 28th of July. The swell is tiny, just 1ft to 2ft, with a period around 9 seconds and a glassy wind state. But the wave energy is pathetic (48-58), and the water temp is sitting at 63°, which is about normal for this time of year. The waves just aren't there.
The whole period is a long, flat, windy stretch. For a spot like Port Isaac, which is a fairly consistent spot, this is a real bummer. It’s the kind of setup that looks more interesting for a kite than a surfboard, with the stronger cross-onshore winds later in the month. There’s nothing to recommend. Hoping the forecasts change, but for now, keep the boards in the van.

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.
