10 Day Forecast for Glyntawe

Page loading ...

Cloudy with some rain to start, brightening up later.

Today:

Rain will affect most parts this morning but will gradually sink southwards and start to clear during the afternoon. Brighter skies will then emerge from the north through the late afternoon and it will feel less humid than recent days. Maximum Temperature 18C.

Tonight:

Dry with clear spells tonight, although there is a chance of one or two light showers. There will be a fresher feel with temperatures falling lower than in recent nights. Minimum Temperature 9C.

Thursday:

A dry, fine day with sunny spells. Temperatures will not be quite as high as the last few days but it will still feel warm in the sunshine. Maximum Temperature 18C.

Outlook for Friday to Sunday:

Dry and fine over this period with sunny spells, with the best of the sunshine likely on Sunday. Each day is likely to feel a little warmer that the last.

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.
