The Lowdown
Alright, surfers, Rusty here. Let's be honest, this is a tough one to write. The sea's been flat and the wind's been all over the place. We're looking at a 16-day window for Port Isaac, and there's a proper drought to start with.
From now, right through until the 11th of August, it's a real struggle. The swell is tiny, barely a ripple, and the wind is mostly onshore or cross-onshore, just junking up what little bit of energy there is. The combined wave energy is pathetic, mostly in the teens and twenties, just weak and listless. The first proper surf recommendation doesn't come until the 12th of August.
There is a little glimmer on the morning of the 5th of August – glassy conditions with a 2ft swell from the NNW. But the period is a short 5 seconds, so it's just windswill, and the energy is only 34. It's a "maybe" for a longboard, but not something to get excited about. The whole month of July and the first week of August are a write-off for a proper paddle. The water temperature is about 65°F which is a touch warmer than normal for this time of year, but that's about the only thing that's slightly above average.
Now, for the standout. It's the 12th of August. We get a little pulse of energy. The swell picks up to 4ft from the WNW in the afternoon. The period is still short, 6 seconds, but the combined energy jumps to 80. It's nothing epic, but it's the biggest we've seen. The wind will be a cross-onshore from the NW at 15 mph, which will chop it up a bit. It's a bit messy, but it's the only window where the waves will be big enough for a beginner to get a few whitewater rides. The swell direction is WSW to WNW, which is a solid match for the break's optimum. Don't expect perfection, but it's the only game in town.
After that, it drops right back off again. The 14th of August morning looks calm and glassy, but with a 0.7ft swell, it's a lake. A long stretch of quiet, lads.
So, to sum it up: the first 12 days are a slog. The only real highlight is the afternoon of the 12th of August. It's not the best surf you'll ever see, but it's the best on offer. Get on it if you're desperate.
Stay frothy, lads.
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.
