Guernsey Weather Fox

Thursday

Weather

A very grey and cloudy day at least until 4 or 5pm. In the morning this cloud will be pretty thick and low, meaning that it will be misty and drizzly in places (mainly around the airport). Wind-wise, the mornings force 4 SSW’ly will relax to a light force 32 SE’ly by evening. That will feel really nice, but the sunshine will be a bit too late in the day to lift the temperature any higher than 20°C. Overnight, it will be mild, with the low cloud and mist returning, blanketing the Island and keeping temperatures no lower than 15 or 16°C.

Surf and the Water

The surf will be increasingly clean, and a good size too… about 5 feet in the morning and 4 feet in the afternoon. Swimming conditions will be best on the north and east coasts in the morning, as well as in the southern corners of the west-coast Bays. Then, apart from the surf-spots, all places will be lovely and smooth in the late afternoon and evening when the wind is near calm. Low tide will be at 11:20am, then high tide will be 7.8m at 5:20pm.

Friday

Weather

A similarly cloudy and misty start to Thursday, but it should brighten up much quicker. Then in the afternoon, soom much higher cloud will spread in, which might eventuate in some rumbles of thunder by evening. There will also be a slightly greater chance of thunder in the middle of the night, but even then it may never happen. It’s nearly always the most uncertain element of the forecast. Wind-wise, we will maintain a light force 2-3 SSW’ly for the majority of the day, which will make the 21°C max feel lovely... and it’s certainly been an unsettled September thus far, so these moments should be seized.

Surf and the Water

Gorgeously clean 3 foot surf and beautifully smooth swimming conditions. Tides will be starting to get large so make sure you leave your towels right at the top of the beach before you take your late afternoon dip. Highs will be at roughly 6am and 6pm (8m and 8.5m respectively). Low water will be just after midday.

The Weekend

Weather

A bit of a dismal downturn in the forecast I'm afraid. Saturday morning feeling lovely and warm, as it hangs on to the same air that made Friday so lovely. Rain at lunchtime will cut the day in half though, leaving us with a cooler and much windier afternoon, a moderate force 4 SW'ly veering to a fresh force 5 W'ly. We will then have heavy showers coming and going through the night and through the majority of Sunday too. The winds light and variable on Sunday morning, but then a fresh and very chilly NNE'ly in the afternoon. The max temps will be 19°C and 17°C respectively, both achieved in the morning, so if you have outdoor plans it might be a good idea to go to bed early and then rise with the lark.

Surf and the Water

The surf is likely to be 2 feet and clean both mornings, then a right old mess in the afternoons. Windsurfing and kitesurfing could be good during those choppy episodes though. As the moon wanes to newness (Sunday evening), the tidal range will be large again, with lows around lunchtime and highs around dawn and dinnertime, increasing from 8.6m on Saturday morning to 9.3m on Sunday evening.

Next Week

Weather

It’s a really uncertain latter part of the forecast, but the current expectation is that Monday will be very wet, Tuesday partially wet and the rest of the week dry. Most notably, it’s going to be on the cool side, with winds switching to a stiff N’ly on Monday and then a gentler NE’ly through the rest of the week.

Surf and the Water

Monday’s surf will be quite chunky and very choppy, Tuesday’s will also be choppy but very small on that day, Wednesday onward will likely be about 2 feet and relatively clean. As for the swimmers, the south coast will offer the smoothest conditions from beginning to end. High tides will be in the mornings and evenings, low tides will be in the afternoons. Big tides… with highs of 9.4m Monday and Tuesday , then gradually dropping until it’s down to 8.4m on Friday evening.
