Alright folks, this is Rusty. Let’s have a look at what’s coming up for Port Isaac.
I gotta be straight with you – the next couple of weeks are looking pretty flat. The swell energy is weak, and the wave comment says "poor surf conditions" right through the entire 16-day window. There’s no standout day, and no real recommendation for a paddle. The first few days of July are tiny, with swell heights barely scraping 2ft and combined energy staying under 100 (73 on Monday the 6th). The wind is mostly cross-on or onshore, so it’s not going to be clean.
We do get a glassy moment on the morning of Wednesday the 8th – light offshore from the North at 5 km/h, which would make it look nice, but it’s still only 2ft of swell. Not enough to get excited about.
The pattern stays the same through the rest of the week and into the second week. There’s a slight uptick in energy on the 10th of July, with combined energy hitting 106 for the Friday morning, but it’s still only 3ft of swell and the report still says poor. The morning of Sunday the 19th sees a bit more energy at 103, with a 2ft swell from the West and a 13-second period – that’s a long-period groundswell, but it’s tiny. The wind is offshore from the ESE at 30 km/h, which is clean but strong. For a beginner-friendly spot like Port Isaac, that’s not really the ticket.
Overall, it’s a flat spell. If you’re desperate for a splash, the glassy morning on the 8th might be your best bet, but don’t expect much. The water temp is a touch warmer than normal at 62°F. For the time of year, that’s a bit above average.
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.
