The Lowdown
Right then, let’s have a look at what’s on offer for The Breakwater-St Ives over the next couple of weeks.
Honestly, it’s a bit of a tough stretch for us here. We’ve got a lot of poor surf conditions and messy wind in the forecast, so it’s not going to be one for the photo album. The water temp is sitting about 64°, which is pretty much normal for this time of year, so at least you won’t need the thickest of rubber.
The first real chance to get a wet suit on comes up on the morning of Sunday the 30th of August. There’s a risk of thunderstorms around, but the wind is cross-off at 19 mph from the SW, and the swell is a 6 ft from the WSW with a period of 9 seconds. The combined energy is moderate (944). It’s marginal, but it’s the pick of a bad bunch early on. The swell is a bit too big for beginners though.
Moving into Monday the 31st of August, we’ve got a 8 ft W swell in the morning, but the wind is a cross-on from the WNW at 16 mph, and it’s got a messy chop. The afternoon eases a bit to 7 ft, and the wind swings to a cross-shore, still with a cross-chop. Not great.
The real stand-out, if you can wait, is the afternoon of Sunday the 6th of September. The wind drops to a light breeze from the SW at 6 mph, giving us a clean, cross-off set-up. The swell is 4 ft from the W with a 10-second period, and the combined energy is moderate (338). This is the best on offer – clean, surfable waves, and not too big. It’s the one to pencil in.
The rest of the run is a bit of a write-off. There’s a lot of wind, a lot of chop, and the swell is either too small or too messy. We see a bit of a pulse on the 2nd of September, a 8 ft WSW swell, but the wind is fresh and it’s only marginal. After the 7th of September, it really drops off. We’re looking at tiny waves and strong winds, with the energy dropping to weak numbers. The 13th of September has a very long-period swell of 15 seconds from the W, but it’s only 2 ft and the wind is fresh and cross-shore, making it lumpy. Not worth the paddle.
So, the takeaway is: the best window is the afternoon of Sunday the 6th of September. The rest of the time, you’re better off doing something else. The Breakwater-St Ives is inconsistent, and this run has shown it.
