The Lowdown
Alright surfers, Rusty here. Let’s be straight with you: the 16-day window for Port Isaac is a real struggle. There’s just nothing good on offer, not a single standout session to get excited about. The forecast is a long, flat, and messy run of poor surf conditions, with very few days offering even a glimmer of hope.
The first week, from the start of August through to the 9th, is dominated by tiny, weak swell. The combined energy is mostly in the low double digits or barely triple digits, ranging from 10 to 161 (moderate), but the real killer is the wind. We’ve got a lot of onshore and cross-onshore winds, often from the NW, which is just not the direction we want. The swell is small, often around 0.7ft to 1ft, and period is short, mostly 7-8 seconds, producing weak, crumbly waves. The water temperature is a touch warmer than normal at 65°, but that’s no comfort when the surf is this poor.
The second week, from the 10th of August onward, is even worse. The swell drops to almost nothing, with combined energy falling to single digits and barely reaching 10. The wind does get a little better on a couple of mornings, like the 11th with a glassy NE and a 12-second period, but the swell is only 0.3ft. It’s just not enough to ride. The 12th and 13th have a tiny pulse of 2ft from the W, but the wind is either onshore or cross-onshore, messing up what little shape there is. The 14th through the 16th are a washout with strong winds and choppy conditions.
Basically, grab a coffee, watch the horizon, and wait for a proper swell. This kind of blank run is normal for the area, but it won’t last forever. There’s just nothing to recommend here.

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.
