The Lowdown
Alright, Rusty here again. Let’s break it down in feet and miles.
The next couple of weeks are a bit of a mixed bag, to be honest. We’ve got a slow start, then a big blow in the middle of next week that churns things up, and finally a real glimmer of hope on the 16th of August. For now, you’ve got to be patient.
Right off the bat, Sunday afternoon the 2nd of August – the water is a touch warmer than normal at 66°, which is a nice little bonus. But the swell is tiny, only 1 ft from the WSW, and the energy is weak (51). It’s rideable, but it’s not going to get your heart racing. The wind is a gentle cross-off from the SE, so it’s clean, but there’s just no push.
Monday, the 3rd, picks up a little with a 3 ft WSW swell and a bit more energy (116), still clean with a cross-off wind. But it’s nothing to write home about. Things go downhill from Monday afternoon through the whole of next week, really. The wind swings onshore, gets strong, and we get a lot of lumpy, choppy, poor surf. From Tuesday the 4th through to Saturday the 8th, the wind is mostly fresh and onshore, and the swell is all over the place, from 5 ft to 8 ft, but it’s all close-range windswell with short periods and messy conditions. The energy gets up to 693 on Wednesday the 5th, but with a howling onshore wind, it’s just a washing machine. Honestly, that setup is more interesting for kite surfing than paddle surfing.
We get a bit of a reset on Sunday the 9th with a cross-shore wind, but the swell is dropping and the energy is low. From there, the waves are small and clean through the middle of the month, but really small – under 3 ft – with weak energy. It’s glassy and clean, but you’re barely going to get wet.
The real standout here comes on the 16th of August. Sunday morning, the 16th, we’ve got a light offshore breeze from the ESE, and by the afternoon it’s dead glassy from the SSE. The swell is a solid 6 ft from the west, with a moderate energy (389-396) and a clean 8-second period. This is genuinely good surf. The optimum swell direction is W, so this is right on the money. The water temps will be fine, and with light winds and glassy conditions, Sennen Cove will be offering up some clean, fun waves. This is the best on offer in the whole 16-day window. The next day, Monday the 17th, has a similar size swell (7 ft) but the wind comes more cross-shore, so the 16th is the real winner.

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