The Lowdown
Alright, let’s break this down for The Breakwater-St Ives. It’s a point break that doesn’t fire all the time – it’s inconsistent, so when the stars align, you better be ready.
Water temp is around 63°F, which is a bit warmer than usual for this time of year – nothing crazy, but nice.
Honestly, the first week is a tough watch. From Sunday morning, 6th September, it’s poor. There’s some swell, but the wind is all over the place. The energy is low – Sunday morning shows 104 (moderate wave energy) and it doesn’t improve much.
Monday the 7th brings a bigger swell of about 7ft from the west with a long 13 second period, and the energy jumps to 1632 (strong wave energy), but the wind is cross-on and the report is poor. That’s a tease. That kind of groundswell needs a point break, but the wind is wrecking it.
Tuesday the 8th through Thursday the 10th is a total write-off – fresh winds, lumpy chop, and poor conditions.
Friday morning, 11th September, is where it gets interesting. We’ve got a southerly offshore breeze at 15 km/h (about 9 mph), clean conditions, and a 5ft west swell with a 9 second period. The energy is 287 (moderate wave energy), but the wind is right and the report says “expect good surf conditions.” For this inconsistent spot, clean 5ft is a real highlight. Saturday morning the 12th drops back to 3ft, so Friday morning is the standout of the first week.
Sunday morning the 13th also looks good – 5ft from the west, 9 seconds, with a southerly offshore breeze at 20 km/h (about 12 mph). Energy is 348 (moderate wave energy) and the report is good again. Two mornings in a row worth getting wet for.
After that, it goes quiet. Monday the 14th has some long period 12 second west swell, but the conditions are marginal. Tuesday the 15th through Saturday the 19th is mostly poor – strong winds, cross-shore chop, and messy surf.
Looking way ahead to Sunday the 20th of September, there’s a promising swell building. The morning shows a 7ft west swell with an 11 second period, and a cross-off breeze from the east-southeast at 30 km/h (about 19 mph). Energy is strong at 1056 (strong wave energy). It’s marked as “marginal” for surf, meaning the tide could be tricky, but there’s potential. That’s a long way out though, so don’t book your flight yet.
Best of the whole run? Friday morning 11th September and Sunday morning 13th September – clean, offshore, and surfable. That’s your window.
