The Lowdown
Alright, let’s break down the surf for The Breakwater-St Ives in imperial over the next couple of weeks.
First week is a tough watch, to be honest. We’ve got a weak, short-period SW windswell hanging about, but the wind is blowing hard from the same direction, making a mess of things. The water here is about 64°, which is normal for this time of year.
Saturday 29th August there’s a risk of thunderstorms and a gusty 22 mph SW cross-offshore wind. The swell is around 8ft from the SW with a short 8-second period – that’s a lot of chop for not much wave face. The combined energy is moderate (606) but the conditions are poor.
Sunday 30th is similar. The swell drops to about 6ft from the WSW, still with a fresh SW wind. Marginal at best.
Monday 31st sees a bigger, lumpy 10ft W swell roll in, but the wind is cross-onshore with a strong 16 mph WNW breeze. The energy is high (2739) but it’s rough and lumpy – one for the kite boarders, not for a clean paddle.
Tuesday 1st September and Wednesday 2nd are flat to weak. Swell dropping to 3ft to 7ft, wind still from the SW, poor quality.
Thursday 3rd and Friday 4th show signs of life – the swell is around 6ft to 7ft, and the period starts to stretch to 11-12 seconds, hinting at a better groundswell. The wind is cross-off on Friday, which helps. Combined energy is strong (1150-1198) but still only marginal for quality.
Saturday 5th to Sunday 6th fades again to 4ft to 5ft, no punch.
Now, the good news. Monday 7th September morning is the best of the first week. The wind turns light from the ESE at 6 mph, making the surf clean. There’s a solid 6ft W groundswell with an 11-second period, and combined energy is strong (981). It might be inconsistent, but the sets will be quality.
Tuesday 8th drops off, and Wednesday 9th is near flat.
Looking further ahead, Thursday 10th September – the swell jumps to 8ft from the WSW, but the real gem is Thursday afternoon: a clean 10ft WSW groundswell with a light 16 mph S offshore breeze. Energy is strong (1242). That’s solid expert territory.
Friday 11th September is the absolute standout. A massive 10ft W groundswell with a very long 14-second period – that’s proper deep-ocean energy. Combined energy is extremely high (5574). Wind is light offshore from the S at 9 mph, making it glassy. This is a massive day for experienced surfers only. The break handles it well as a point.
Saturday 12th eases to 5ft, still with light offshore winds and an 11-second period. Sunday 13th morning is glassy – wind is a whisper from the WSW at 3 mph – with a clean 6ft W swell at 10 seconds and combined energy of 1139. Beautiful morning for an intermediate surfer.
The one to circle on your calendar is Friday 11th September – it’s the big one. For a more relaxing wave, Monday 7th September morning and Sunday 13th morning are your best windows.
