The Lowdown
Alright crew, Rusty here. Got to keep it real – the next couple of weeks look tough for a decent wave. We’re looking at a long stretch of onshore wind and sloppy swell, so don’t get your hopes up just yet.
It starts off with a washout. From Monday the 24th right through the end of the month, the surf is tiny with onshore winds and no real power. The swell energy is barely there, as low as `3` to `9`, so you’re better off staying dry. A long, flat spell.
By Friday the 28th, there’s a little bump in combined energy hitting `124`, but it’s still a messy cross-onshore wind, and the swell just isn’t linking up. Not worth the rubber.
Heading into early September, it’s more of the same – plenty of wind, a lot of chop, and not much quality. There’s a quick pulse of energy around Sunday the 6th and Monday the 7th, with combined energy hitting `245` and then a big spike to `777` on Monday afternoon. That’s the biggest number of the whole run, but it comes with a strong onshore wind and a note of “poor surf conditions.” That’s a no-go for a paddle board.
The one tiny standout in this whole mess is way out there. Look at Monday the 7th of September morning. We get light `NW` winds at just `3 mph` – that’s glassy, cross-shore, clean conditions. The swell is only `2 ft` from the `SW`, but the period is a massive `16 seconds`. That’s a true, long-period groundswell. The combined energy is moderate at `204`. For a reef or point, that kind of period can turn a tiny wave into something with real shape and make it fun. But at a beach setup like Compton Bay (Isle of Wight), it’s a bit of a wild card – that long period can make it break too straight. It’s a long way off, so don’t bank on it, but if that light wind sticks and the swell fills in just a little, that morning might be your only chance in the whole 16 days. A sliver of hope.
After that, Tuesday the 8th morning looks rough again, with an `8 ft` swell and strong cross-onshore winds – a blown-out mess, and with that size it’s for experts only if anyone, and the wind will probably make it better for kite surfers than paddle surfers.
So, bottom line: a lean stretch. Keep your eyes peeled for that 7th of September window.
Rusty.

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.
