The Lowdown
Alright, folks, Rusty here. Got to be straight with you—this is a tough one. We’ve got a full 16-day window, but it’s flat for Port Isaac. There’s no surf worth chasing from now through the end of the month. The first recommendation isn’t until the first surf shows, and honestly, it’s a grim wait.
So from Wednesday, 15 July, right through to the end of the month, we’re looking at a stubborn run of tiny, weak waves with poor surf conditions. The combined swell energy barely gets into double digits for most of it, hanging around 14 to 39, which is as weak as it gets. Winds are mostly onshore or cross-onshore, and the swell heights are stuck between 0.7 ft and 3 ft. It’s not even worth paddling out for.
There is a flicker of hope right at the end. On Saturday, 25 July, the morning brings a bit more size—around 4 ft from the NNW—but it’s still onshore wind and the conditions are described as “poor.” The combined energy jumps to 121, which is moderate, but with the wind howling it’s going to be messy. That afternoon, the energy rises to 173, but it’s cross-onshore and choppy. This is more of a kite-surfing setup than a paddle session. The Sunday after that drops back down to nothing.
The water temperature is about average for the time of year, so no surprises there.
Bottom line: this is a total blank run. For Port Isaac, it’s not unusual to see a dry spell like this, so don’t lose hope. Forecasts can change, but for now, leave the board in the car and go for a walk.
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.
