Guernsey Weather Fox

Monday

Weather

Pretty much wall to wall sunshine. The airflow rather cool though, coming from the NNE (light F3 for the most part). Max temp 20°C, Max UV 7. The south-coast beaches will be the warmest areas and, with a low spring-tide in the early afternoon, their vast stretches of golden sand will be looking irresistible.

Surf and the Water

Some very small and dribbly surf is likely on the west-coast (only just enough to satisfy any kids who are learning). As for the swimming, much like the sun-bathing, a trip to one of your favourite south-coast beaches will be well worth the effort.

Tuesday and Wednesday

Weather

These two days stand out as the windy ones (moderate force 4 to fresh force 5). That wind will still be NE’ly in direction, so it will be the same areas that feel warm in shelter (central valleys, south-coast bays and the northern corners of the west-coast bays) and it will be the same areas that feel chilly in exposure (just about everywhere else on the island). With some cloud spells in the mornings but almost flawless blue skies in the afternoons, we will probably see max temps of 20-21°C with a sunburny max UV of 7. During the nights, under starry skies, the air temperature will only fall a couple of degrees below the sea temperature, with minima of 15-16°C.

Surf and the Water

The west-coast surf will be flat as a lake, but the windsurfing and kite-surfing conditions should be a blast. If it’s swimming and coasteering that you fancy, then the south-coast will be your best bet, although the northern corners of the west-coast bays will also be ok when the tide is high (breakfast time and dusk).

Thursday and Friday

The high-pressure system (centred over Scotland), will just become a tiny bit weaker#, causing virtually no change in our weather from the previous two days. The only noticeable difference, probably being slackening of the NE’ly wind (light force 3 to moderate force 4), just making it a little more pleasant to go out for a bike-ride or to have a game of tennis etc.

Surf and the Water

There’s just a chance (low confidence) that the west-coast surf will become rideable or even quite good, as small long-period waves arrive from the mid-Atlantic depression that is expected to evolve from Hurricane Henri. Otherwise, it will be the same areas that are best for swimming and coasteering. The tides will be a bit smaller and later though, with highs just under 9m in the late mornings and lows in the late afternoons.

The Weekend

Staying dry and settled but possibly warming up a couple of degrees (max temps of 21-23°C) as the breeze might veer to a due E’ly direction, bringing us a little more influence from the warm continent and a little less influence from the cool Channel. If this wind-change does occur then it will be good news for beach-goers as conditions become more widely comfortable along the west coast.

Surf and the Water

If we are treated to some swell from that there retired hurricane, then it will run its course through the weekend, with clean 2-3 foot waves possible on Saturday, probably dropping off to 1 foot or perhaps flat on Sunday. High water will be about 8m on Saturday (10:50am) and about 7.5m on Sunday (11:20am).
