The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer.
Well, I’ll be honest with you, mate, it’s a pretty grim start. We’re looking at a real dry spell right out of the gate. For the first week, the surf is just not there. From Sunday the 26th of July right through to Saturday the 1st of August, it’s a write-off. The wind is howling from the northwest, cross-on, and the swell is weak and messy. Don’t even bother waxing up.
We’ve got a big gap of nearly a week before we see anything worth paddling out for. The first real glimmer of hope comes on Sunday the 2nd of August. Port Isaac is the only spot we’ve got, and it’s a beginner-friendly break that’s fairly exposed to the west-northwest.
Sunday 2nd August – Morning Windows
The morning session is the closest thing to decent we’ll see for a while. The wind goes glassy, a light south-southwest breeze, and we’ve got a 3ft swell rolling in from the west with a period of 10 seconds. The water temperature is sitting at 64°, which is a touch warmer than normal for this time of year. The combined wave energy is moderate (179). It’s surfable, but the conditions are very ordinary. Don’t get your hopes up for anything epic, but for a beginner, it’s a chance to get wet.
Monday 3rd to Wednesday 5th August
Back to nothing. The wind picks up, the swell drops, and it’s all poor surf conditions. Just a lot of cross-offshore winds and tiny waves.
Friday 7th August – The Big One?
Now, here’s something interesting. On Friday the 7th of August, the forecast shows a serious spike in energy. We’re looking at a 10ft swell from the west in the morning, with a period of 10 seconds. The combined wave energy is massive (1760). The wind is cross-shore, which is a bit of a downer, but the sheer size is going to be something. This is expert territory at 10ft – too big for beginners. The afternoon sees a 8ft swell from the west-northwest, still very strong (1368), with a cross-offshore wind. It’s still a marginal forecast, but for the experienced crew, this could be a real standout, albeit a messy one.
Saturday 8th August onwards
The week after that is all onshore winds and dropping swell, so it’s back to the quiet life. The swell is too small and the wind is too strong to bother.
The Bottom Line
If you’re a beginner, the only real window is the morning of Sunday the 2nd of August, but it’s not great. The only standout for the experienced surfers is Friday the 7th of August, when the swell ramps up big time, but the wind is a problem. The crowds at Port Isaac can be a thing sometimes, so keep that in mind.
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.
