The Lowdown
Alright, let me have a look at this forecast. Honestly, it’s a flat spell for Falmouth - Swanpool (Falmouth). We’re talking a full 16-day window and there is pretty much nothing doing. The first record kicks off on Sunday the 13th of September, and straight away we’re looking at piddly 0.3 ft swells with a combined energy of just 7 – that’s not even a ripple, that’s a yawn. The water’s sitting at 64.2°, which is a touch warmer than normal for this time of year, but that’s the only real excitement.
We go through the whole first week with the same story: tiny 0.3 ft waves, cross-off winds, and energy readings down in the single digits or low teens. Tuesday the 15th gives us a clean offshore wind from the WNW at 19 mph, but there’s no swell to work with. It’s frustrating. By the 16th and 17th, there’s literally zero swell energy in the water.
Then we hit a gap of nothingness. From the 16th of September right through to the 22nd, it’s just flat. The pride of the forecast comes late on the 22nd of September, where an east swell creeps in at 1.0 ft, but it's only a 6-second period and weak energy of 5. The next few days try to build. The 24th sees a 3.3 ft east swell with a short 5-second period and 51 energy – it’s choppy with a cross-onshore wind. The standout, if you can call it that, comes on the 25th of September. Friday morning and afternoon offer 4.3 ft from the east, 6-second period, and 135 energy (moderate). But the wind is a fresh cross-onshore from the ESE, making it lumpy and messy. That’s the best the whole 16-day run has to offer, and it’s only for experts given the size, but the wind ruins it.
We wrap up the period on the 28th with more tiny, weak, onshore wind swell. To be brutally honest, there is no genuine standout session here. The best advice I can give is to leave the board in the car and enjoy a cold one on the beach.
