The Lowdown
Right then, let’s have a look at what’s on the cards for The Breakwater-St Ives. This is a point break with an inconsistent reputation, so when it’s on, it’s a treat, but it takes a fair bit of patience. The water temperature is about average for the time of year, nothing out of the ordinary there.
To be brutally honest with you, the first two weeks of this forecast are a proper write-off. We’re looking at a solid 12-day stretch with nothing worth paddling out for. The swell is there, but the wind is just a mess – cross-off, cross, and cross-on breezes up to 19 mph or more, making a mess of things. The combined wave energy hits 388 (moderate) on the 5th of August with a 6 ft W swell, but that blustery wind just kills it. It’s a frustrating wait.
The first real glimmer of hope doesn’t come until Monday, the 17th of August. The morning session is the standout. We’ve got a clean 4 ft swell from the west, with a period of 9 seconds, pushing a combined energy of 231 (moderate). The wind is a gentle cross-off from the southwest, which is clean and light, giving us some shape. It’s not massive, but it’s the best of a very quiet bunch. The afternoon follows with a similar 4 ft swell from the west, a 10-second period, and 266 energy, but the wind picks up to a moderate 12 mph cross-off, so the morning is the pick of the day.
After that, the 18th and 19th look like they’ll turn back into a windy, lumpy mess, so that Monday window is the one to circle. Remember, the break is inconsistent, so you’ve got to be on it when it’s clean.
