Kimmeridge Bay Surf Forecast and Surf Report

Alright, Rusty here. Let me break down what's on the cards for Kimmeridge Bay over the next couple of weeks.

Straight up, if you're looking for a clean session, this is a tough stretch. The whole 16-day window is riddled with poor surf conditions and messy winds. There are a handful of days where the swell gets up there, but the wind just won't play ball. The first real glimmer of anything usable doesn't show up until Saturday the 5th of September, and even then, it's pretty small.

The opening weekend is a write-off. Strong cross-onshore winds, messy conditions, and the swell is either too short-period or just plain choppy. On Sunday the 29th of August, the swell pumps up to 12 ft out of the SW, but with a strong cross-onshore wind, it's going to be a washing machine—definitely not one for a paddle. The combined wave energy for that afternoon hits 1785, which is very strong, but it's all for nothing with that wind.

Things finally start to look up on Saturday morning, the 5th of September. We get a bit of relief with a clean, light offshore breeze from the WNW. The swell is small, only 3 ft from the WSW, but with gentle winds and a period of 6 seconds, it'll be glassy. Combined energy is weak at 48, so it's a small-scale session, but it's the cleanest the bay will see for a while.

The most notable window comes around the 8th of September. On Tuesday afternoon, the swell jumps to 12 ft from the WSW with a period of 9 seconds and very strong combined energy at 1724. The data notes wind and tide are favorable, but it's flagged as likely too big for the break. This is a reef setup, and with a long-period groundswell like that, it'll be a heavy, powerful wave. That's strictly for experienced surfers only. The morning of the 8th also has 10 ft from the WSW with 1205 energy, but the cross-shore wind will make it lumpy.

After that, the following week fades out quickly with small, weak swells and onshore winds, especially with a risk of thunderstorms on the 12th. Nothing else stands out as a good option.

Best Bet: If you're desperate for a clean wave, Saturday morning, the 5th of September is your only real shot for a relaxing, small-wave session. Otherwise, the bigger, heavier option on Tuesday the 8th of September is the standout for experts, but only if you're confident tackling a big, powerful reef break.

Kimmeridge Bay is a reef break, fairly exposed to the SW swell, and on the morning of the 5th, the water temperature is noted as being 69°, which is much warmer than normal for this time of year (a 4° anomaly), so you might get away with a thinner wetsuit than usual.

Keep an eye on the wind forecasts, because if that Tuesday session cleaned up, it would be a proper beast. For now, that's the pick of a tricky bunch.

Stay safe, Rusty.
