The Lowdown
Alright, Rusty here again. Let’s break down the same stretch in feet and miles per hour.
First few days are a total dud. From now through Saturday the 1st, we’ve got tiny, weak swell and wind that’s all wrong. The gap is real – nothing worth paddling for until Sunday morning the 2nd.
Sunday the 2nd is the first chance, but it’s small. Sennen Cove has a 2ft west swell, but the wind goes light ESE cross-off, cleaning the surface. The energy is weak (42), so it’s a longboard day if you’re keen. The afternoon glass-off is the best of it.
The true standout: Monday morning, the 3rd of August. That’s the one to circle. We’ve got a 3ft groundswell from the WSW, a 9-second period, and the wind goes glassy. The water temp is about average for the time of year. The combined energy is moderate at 107, and the waves will be clean, lined up, and super fun. Sennen is very consistent, so you’ll get waves. Crowds are possible, but that’s the price you pay for perfection. This is the best session of the whole outlook.
Tuesday the 4th and Wednesday the 5th bring some size (up to 3ft), but with strong cross-to-onshore winds that’ll chop it up. Not for paddle surfing, but the kite crew might have a go.
In the second week, Saturday the 8th of August shows a 5ft southwest swell with a light offshore wind from the ENE. The energy is moderate (163), and the waves will be clean. It’s a decent beginner-to-intermediate window, but the swell is short-period (6 seconds), so it’ll be a bit weak. Sunday the 9th has a 4ft SSW swell in the morning with a cross-off breeze and a solid energy reading of 218, but the wind gets fresh by the afternoon. Morning only.
After that, the surf fades out. A big gale on the 12th blows everything out, and the final week is tiny, weak, and blown out.
Bottom line: Monday the 3rd is your best bet – glassy, clean, and fun. Saturday the 8th is a backup if you miss it. The rest is a waiting game.
Rusty.

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 Sennen Cove 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.
