The Lowdown
Alright folks, Rusty here. Well, I’ve got to be straight with you – the next 16 days are looking pretty grim for Port Isaac. We’ve got a long stretch of nothing to get excited about, so let’s break it down.
The first day with any surf to speak of kicks off on Tuesday the 21st of July. But honestly, it’s tiny. We’re talking scraps at 1 foot from the west with a 10-second period. The combined energy is weak (31), and it’s blown out by a cross-on breeze. Not worth paddling out for.
Wednesday the 22nd sees a little bump up to 3 feet but it’s short period stuff at 5 seconds, and the wind is howling onshore and cross-onshore. The energy is still feeble (56), and it’s just messy. Thursday morning the 23rd brings a glassy window with 2 feet from the NNW, but the period is still short (6 seconds) and the energy is pathetic (37). It’s clean, but there’s no push to it.
From Friday the 24th through to the end of the month, we’re looking at a flat spell. Swell heights drop to 0.7 feet or 1 foot, with combined energy readings in the single digits or low teens. It’s basically a lake. There’s a brief spike on Sunday the 26th of July, with 7 feet from the WNW at 8 seconds, but the wind is howling onshore at 19 mph. The energy jumps to 426, but with that wind, it’s just a churned-up mess. The whole week following is more of the same – small, short-period, and wind-affected.
Into the first week of August, things don’t improve. The 1st of August has some clean 2 foot waves from the west, with a 10-second period, and cross-offshore winds. The energy is still low (56). It’s clean, but it’s barely a ripple. From there, it’s a slow fade to nothing.
There really isn’t a standout session in this entire 16-day window. The only time we see any size is on the 26th of July, but the wind is so bad that it’s more of a kite-surfing setup than a paddle-surfing one. The water temperature is about average for this time of year, so no surprises there.
Hang in there, crew. This is a blank run. It won’t stay poor forever, but for now, the forecast is a bust.
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.
