The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking for Port Isaac over the next couple of weeks. Gotta be straight with you – it’s a tough stretch. We’re looking at a long, dry spell of flat or weak, messy conditions. The first proper wave that’s even worth paddling out for doesn’t show until Monday the 3rd of August, so you’re looking at nearly a whole week of nothing much to get excited about before that. Even then, it’s nothing special.
Our best shot, and really the only thing I’d call a standout, is going to be Port Isaac itself. For a beginner-friendly spot, it’s a good, forgiving wave most times. The water is sitting at a touch warmer than normal for this time of year, 64°, which is nice.
Alright, so let’s talk about that Monday the 3rd of August. It’s the first day with any surf. You’ve got a weak little 2ft swell rolling in from the west, with a 9-second period, so the combined energy is tiny at 79. It’s nothing to write home about. But the wind goes glassy in the morning, and that makes all the difference. It’ll be clean, even if the waves are small and gutless. Afternoon gets a bit lumpy as a cross-shore kicks in. Crowds are a possibility here sometimes, so if you want the best of it, get out early.
The swell tries to pick up around the 4th and 5th of August, with heights pushing 3ft to 5ft and the energy climbing into triple figures (137 to 199). But the wind is either cross or onshore, and it gets choppy and lumpy. Not worth the hassle for a paddle board. If you’re a kite surfer, that Tuesday the 4th afternoon with a fresh cross-shore and 5ft swell might look fun, but for a regular surfer, it’s a pass.
The second week is pretty bleak. The 10th of August brings the biggest combined energy of the whole run at 304, with a 5ft west swell and a 9-second period. But it’s blowing a fresh 19 mph cross-shore wind, turning it into a lumpy, messy mess. It’s just not clean. The rest of the days are small, weak, and either onshore or choppy. You get a clean window on the 12th of August, but the swell is a tiny 2ft.
Honestly, for a spot that’s fairly consistent, this is a disappointing run. But forecasts can change. For now, mark your calendar for the morning of Monday the 3rd of August for the cleanest, most surfable waves on offer. It won’t be epic, but it’s the best we’ve got.
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.
