10 Day Forecast for craig-y-nos

Page loading ...

Low cloud and patchy drizzle, with some heavier rain tomorrow.

This Evening and Tonight:

Patchy drizzle will continue tonight, with coastal low cloud soon moving back inland. The wind will start to ease, however towards dawn more persistent rain will arrive in the northwest. Minimum Temperature 13C.

Wednesday:

Outbreaks of occasionally heavier rain will slowly move southeastwards tomorrow, with grey skies. Behind the rain some sunshine will develop in the northwest later though. Maximum Temperature 19C.

Outlook for Thursday to Saturday:

Thursday and Friday will feel fresher, and chilly by night. There will be plenty of sunshine by day though, and it will start to become warmer on Saturday.

Day 6 to 15

Sunday and Monday will both be largely fine and dry days across much of the UK, with plenty of warm sunshine in store. It is however likely to turn cloudier and breezier across northwestern parts with some outbreaks of rain possible at times, and temperatures here will be nearer the seasonal average. During the last week of the month dry, fine and very warm, sometimes hot, weather is expected to continue in southern and central parts and this fine, settled weather is also expected for much of the week across northern parts of the country too. From time to time however, conditions will become unsettled and generally cooler in the north or northwest, with short-lived spells of rain or showers possible along with stronger winds.

Day 16 to 30

Although confidence is low for the start of July, early indications are that the first half of the month may well bring a good deal of dry and settled weather for many areas across the UK. In southern and eastern parts temperatures are expected to be warm, and sometimes very warm. Northern and western areas are more likely to see changeable spells though, with showers and more persistent rain at times. During these changeable spells temperatures will be close to average for the time of year, but there will be some drier and warmer interludes here too.
