Seven day Guernsey weather forecast for 12 June 2026

Friday

Weather

A fresh decreasing moderate W’ly wind will bring a cloudy and misty day, with only a few hours of respite in the afternoon. West-facing slopes and as well as the high ground of the Island, such as the airport area, will see quite a lot of fog and maybe a little drizzle. However, sheltered eastern areas, such as Town and Fermain, should have better visibility and maybe even some brightness in the afternoon. Temps should peak around the same value (16°C) as Thursday, and then fall to the same overnight minimum (13°C) as Thursday night.

Surf and the Water

Choppy surf, but not quite as bad as the last couple of days. Waves will generally be around 3 feet and plenty surfable, even if very poor in quality. Swimming conditions will be best in the east. Windsurfing/kitesurfing conditions will be best in the morning. Low tide is around 10:50am. High tide is around 5pm (roughly 8m).

Saturday

Weather

Low cloud first thing means that maybe there will be a bit of mist and hill fog until mid-morning. The rest of the days will be increasingly sunny though, with the WNW’ly wind decreasing from light force 3 to light force 2. This should make things considerably warmer than previous days, so we can expect a top temp of 19°C or maybe even 20°C.

Surf and the Water

Much cleaner surf, roughly 3 feet, especially in the latter part of the day. That’s also when the wind will be lightest and the weather finest, so obviously the best time for swimming too. Low tide is around 11:50am. High tide is around 6pm (roughly 8.4m).

Sunday

Weather

A straightforward sunny day, with a gentle force 3 ENE’ly breeze, meaning that we benefit from a little continental warmth, rather than yet more Atlantic coolness. 22°C is the likely max temp, but whilst you are enjoying it (much the same as on Saturday afternoon), don’t forget that the UV index will be very high, given that we are less than ten days away from the solstice... so it’s V important to protect your skin between mid-morning and late-afternoon.

Surf and the Water

Beautifully clean surf. Wave heights will gradually reduce from 3 feet to 2 feet through the day. Tides will be low at lunchtime and high roughly at dawn and dinnertime (8.5m in the morning, 8.8m in the evening).

Next Week

Weather

Wind direction is very uncertain from day to day, but with high pressure centred very nearby, we can be pretty sure that those winds will be very light. Sunshine will be aplenty, but there is the possibility of some fog banks in the Channel on Tuesday, and maybe some thundery showers on Friday. Max temps should be comfortably in the low twenties every day… quite possibly the mid-twenties at times. Furthermore, with the summer solstice only being days away, the UV index will be V-high, likely peaking at a value 8 each lunchtime, meaning that some sort of sun-protection will be essential between roughly 10:30am and 4:30pm.

Surf and the Water

Wave heights will vary between 1 and 3 feet, and generally be clean throughout. Some lovely swimming conditions too, thanks to the light winds and lovely weather. Tides will be high in the mornings, slipping forward from breakfast time Monday and Tuesday, to late morning Thursday and Friday. Low tides will be in the afternoons, and the second high tides of each day will generally be around dusk. (big tides, ranging between 8.6m and 9.3m).

The next forecast update will be on Sunday or Monday…
