The Lowdown
Right then, let's have a look at what's on offer for the next couple of weeks. The forecast is a bit of a mixed bag, with some real promise but a fair bit of waiting involved.
The first chance to get wet looks like Thursday morning, the 3rd of September. The Breakwater-St Ives (United Kingdom) will see a 5ft combined swell from the WSW at 8 seconds. The wind is cross-offshore, but it's a moderate breeze at 12 mph, so it'll be a bit lumpy. The combined energy is moderate (344). The water temp is about average for this time of year at 63°. It's a start, but not the best this spot can offer.
The real standout for the entire outlook is the Saturday morning and afternoon, the 5th of September. We've got a 5ft swell from the WNW with a very long period of 12 seconds. That's a proper groundswell. The wind is glassy at 3 mph in the morning – absolutely perfect conditions. The combined energy is strong (636). This is the pick of the fortnight. The afternoon follows with a slightly smaller 4ft swell from the same direction, but with a light breeze and clean conditions. The long period means sets will be spaced out, making paddling out easier, and it's a point break, so it should handle that long-period energy well. This is when you want to be in the water.
Sunday the 6th drops right off, with tiny weak swells, and then Monday the 7th sees a big jump in size. The morning shows a 8ft swell from the NW with a long period of 13 seconds. The combined energy is very strong (1822). However, the wind is a strong cross-onshore at 16 mph, so it's going to be a messy, lumpy, and choppy affair. Not good for surfing. The afternoon is slightly better with a cross-shore wind, but the swell is still big and messy.
After that, the week from the 8th through the 11th of September is a write-off. The wind is either cross-onshore, fresh, or just creating chop, and the swell quality is rated as poor. The break is inconsistent, so this is a normal bleak patch.
The next glimmer of hope comes on Saturday the 12th of September. The morning has a 3ft swell from the WNW with a 10-second period and a light cross-offshore breeze. Clean conditions. The energy is moderate (413). The afternoon picks up to 5ft from the same direction with a longer 11-second period, but a stronger breeze makes it marginal. The morning is the call here.
The final highlight is on Tuesday the 15th of September. The morning has a 4ft swell from the W with a 9-second period and glassy conditions. This is another absolute gem, perfect for a quiet session. The combined energy is moderate (278). Given the window is far out, it's a promising but less certain call.
So, to sum it up: your absolute best bets are the Saturday morning of the 5th of September for the best quality, and the Tuesday morning of the 15th of September as a quieter, equally clean option. Don't waste your time on the big, windy stuff in between.

Information about the The Breakwater-St Ives Surf forecast

A general guide to surfing at The Breakwater-St Ives can be found by selecting the local surf guide option on the grey menu.
