The Lowdown
Alright, let's get a look at the forecast for Port Isaac over the next couple of weeks.
It's a bit of a slow one, to be honest. We're looking at a long stretch of small, sloppy surf with the wind blowing the wrong way most of the time. The water's sitting around 63°F, which is a touch warmer than usual for this time of year, so at least you won't be freezing your toes off.
The first real chance of something to get excited about comes on Saturday, August 1st. The morning shows a 5ft swell from the west, with a 12-second period, giving it some decent energy (714). But the wind is from the WNW, blowing cross-onshore, which will mess up the surface. It's a marginal one, and the tide might not help. The afternoon drops to 5ft, so the morning is the better bet, but the wind is still a problem.
The real standout, if you can call it that, is the morning of Tuesday, August 4th. The wind swings around to a strong SSW, blowing cross-offshore, and the swell is 4ft from the west with a 9-second period. The energy is a moderate 190. That cross-offshore wind is exactly what you want for a spot like Port Isaac – it'll clean everything right up. The wind is strong, so it'll be a workout getting out, but the waves should be glassy and lined up. By the afternoon, the wind is a strong breeze, 45 km/h, still cross-off, and the swell bumps up to 5ft. That's a serious session for a confident surfer, but the wind is howling, so it's not for the beginners.
After that Tuesday, it's pretty much back to the small stuff. The last week of the forecast is mostly 1ft waves and onshore winds, so don't hold your breath. The biggest gap in any decent surf is from right now until that Saturday the 1st, so it's a proper dry spell.
Overall, it's not a classic. The best bet is that Tuesday the 4th for the cleanest, most powerful waves, but be ready for a strong wind. For the rest, it's a waiting game. Things can change, and it never stays flat forever, but right now, I'd be looking at other plans.

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.
