The Lowdown
Alright folks, let’s talk about what Compton Bay is showing us.
Honestly, the whole 16-day picture is a bit rough. The first week is a total washout. We’re talking about a lot of onshore wind and messy surf. That first real chance of anything decent doesn’t arrive until pretty deep into the second week.
Starting out, it’s all onshore southwesterlies and short-period, weak swell. On Wednesday the 2nd, you’re looking at a 3ft swell with a combined energy of just 51, and that’s useless with a 15 mph wind blowing right onto the faces. It’s a no-go. The pattern of choppy, poor surf continues through the 9th. The swell gets bigger, like 8ft on the 4th, but the wind is just wrecking it.
You have to wait all the way until the morning of Friday the 11th of September. That is a long, quiet stretch. On that morning, we finally see something worth talking about. The swell is a clean 7ft, and the wind is a light 10 mph cross-offshore from the north-northwest. That’s the good stuff. The combined wave energy is a solid 349, and the water is a balmy 69°F, which is crazy warm—4°F above average for this time of year. That is very unusual. It’s a little big for beginners, but for the rest of us on a step-up board, it’s the best window in the whole outlook. The consistency is decent, but don’t expect to have it to yourself; the crowds are showing up "sometimes," which means it'll be a bit lined up.
After that, we get some more swell on the 16th, with waves pushing 10ft, but again, the wind is a fresh cross-shore or onshore from the west. The 17th morning offers a tidy 5ft groundswell with a clean cross-offshore breeze, but the afternoon turns onshore again. It's just a game of finding a clean hour.
For a dedicated surfer, this is a pretty barren run. The only real highlight is that Friday the 11th morning. If the wind holds, that session could actually be good. The rest of the time looks better for the kite crew than us.

Information about the Compton Bay Surf forecast
The above surf forecast table for Compton Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Compton Bay can be found by selecting the local surf guide option on the grey menu. Our Compton Bay 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 (Compton Bay) 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 Compton Bay 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.
Compton Bay is 14 km (9 miles) from Newport. If you plan a holiday in Isle of Wight, look for hotels and other accommodation in Newport. Newport has rooms for a wide range of budgets as well as car hire and transport links.
