The Lowdown
Alright, Rusty here. Let’s get straight into it.
Honestly, it’s a tough stretch ahead for Kimmeridge Bay (reef). The next couple of weeks are looking pretty grim for decent surf. We’ve got a long dry spell at the start, so don’t bother paddling out until the very end of the period.
From Sunday 13th right through to Tuesday 22nd September, it’s a real struggle. Swell is tiny, mostly under 3ft, and the wind is mostly cross-on or cross, with a lot of chop. The combined energy is weak, sitting at 56 or lower for days. The water temperature is 67°F, which is a notable 6°F warmer than usual for the time of year – that’s very unusual, so at least you won’t be cold while you’re waiting.
Wednesday 23rd September morning finally shows a bit of life. Swell picks up to 4ft from the WSW with a period of 5 seconds. The wind goes offshore from the N, so it’s clean. Energy is still moderate at 83. It’s surfable but nothing special. The afternoon is similar, with the same 4ft WSW swell, offshore from NNE, and a combined energy of 95. It’s clean but very ordinary. Crowds are often at Kimmeridge, so expect company if you go.
After that, it drops off again. Thursday 24th and Friday 25th are tiny – barely a ripple. Then Saturday 26th shows a bit more size, 4ft to 4ft from the E, but the wind is cross and it’s choppy. Not great.
The only real standout comes right at the end. Sunday 27th September morning: swell builds to 5ft from the ESE, period 6 seconds, with cross-off wind and clean conditions. Energy is moderate at 135. By the afternoon, it’s 5ft from the E, cross wind, energy up to 154, but a bit choppy. Monday 28th September morning is the best of the lot: 5ft from the E, period 6 seconds, cross-off wind, clean, with energy at 183 – moderate but the biggest of the forecast. This is for experienced surfers only, as it’s over 5ft. The swell direction is from the E, but the optimum here is SW, so it’s not perfect. Still, it’s the closest we get to a decent session in the whole 16 days.
So, if you’re keen, mark your calendar for Sunday 27th and Monday 28th September. The rest? Leave the board at home.
Rusty.

Information about the Kimmeridge Bay Surf forecast
The above surf forecast table for Kimmeridge Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kimmeridge Bay can be found by selecting the local surf guide option on the grey menu. Our Kimmeridge 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 (Kimmeridge 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 Kimmeridge 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.
