The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for our stretch of coast.
Right off the bat, I gotta be straight with you – it’s a tough run. We’re looking at a proper drought to kick things off. The first real chance of a surfable wave doesn’t show up until Sunday, the 2nd of August, and even then it’s nothin’ to write home about. The energy is weak, with combined swell energy readings barely cracking 50 (57) on the Saturday morning, and the wind is messy. We’ve got a solid 10-day stretch of poor surf conditions, with cross-onshore breezes ruining any chance of a clean face. The water temp is sitting at 66°F with a 4°F anomaly, which is much warmer than usual for this time of year – feels like a warm bath, but the waves just aren’t cooperating.
The first flicker of hope comes on Sunday the 2nd of August. The wind finally swings offshore from the ESE, cleaning things up. The swell is tiny, only 2ft, but the morning session might be just about ridable for a log. The afternoon sees a slight bump in period to 10 seconds, but the height drops to 1ft – it’s a knee-high dribbler, but it’s clean. It’s a “surfable waves but very ordinary conditions” kind of day.
Monday the 3rd of August is the first real standout of the whole forecast. The morning delivers a clean 3ft of swell from the WSW, with a period of 9 seconds and a cross-offshore breeze from the SE. The combined energy jumps to a solid 151, which is genuine moderate energy. This is the best on offer. Sennen Cove is an exposed west-facing beach, so that 3ft of WSW swell will wrap in nicely. The water is still warm, and the offshore wind will make for clean, lined-up waves. It’s a beginner-friendly spot, and with the swell just over 3ft, it’s perfect for the learner crew. Expect crowds to be possible here, as it’s a very consistent spot when it’s on.
The rest of the week is a write-off. Tuesday the 4th brings a lumpy 4ft – too much wind and a short 7-second period make it a mess. Wednesday the 5th has a raw 22 mph nor’ly blowing through. Thursday and Friday are tiny, with cross-shore chop. The wind stays onshore or cross-shore for days.
Looking further out, there’s a glimmer on Saturday the 8th of August. The morning session sees a glassy, 4ft WSW swell. The combined energy is 110, and with 7-second period it’s a bit period-challenged, but the glassy conditions will make it look better than it is. The swell direction is a solid match for the optimum W. It’s a hopeful morning, but it’s a long way off.
The following week is a bit of a mixed bag. The 10th of August has a tiny 1.0ft with a 11-second period – that long period will make for some clean, mushy lines on a glassy morning, but you’ll be working for every inch. The 11th of August offers another glassy morning with 2ft of 9-second WSW swell. The combined energy is only 75, so it’s weak, but the glassy conditions are a treat. After that, the wind gets nasty again with a risk of thunderstorms on the 13th and strong breezes through the 15th.
So, to sum it up: the one true standout is Monday the 3rd of August. Clear skies, offshore wind, and a solid 3ft of groundswell. Get on it. The Saturday the 8th morning is a promising second option if the long-range forecast holds. Otherwise, it’s a waiting game. The water is unusually warm, but the waves are stubborn.
Rusty.

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.
