UK forecast for the next 5 days

Sunny spells in the west Tuesday, cloudier in the east.

This Evening and Tonight:

Becoming mainly cloudy across eastern and perhaps central England with increasing amounts of hill fog and patchy drizzle. Elsewhere, with light winds and clear spells, a few fog patches are likely to develop. Chilly in the north and west.

Tuesday:

Early fog patches clearing, then northern and western areas mainly dry with warm sunny spells. Probably cloudier in parts of eastern and central England, with the odd shower possible.

Issued at: 1700 on Mon 01 Sep 2014

Outlook for the UK over the next 6-30 days

UK Outlook for Saturday 6 Sep 2014 to Monday 15 Sep 2014:

Many places dry through the weekend, with variable, but often large amounts of cloud and some bright or sunny spells, but there is an increasing risk of rain or showers spreading across southern and southwestern areas, possibly extending to central areas by the end of Sunday. Into next week, still a good deal of dry weather, especially towards the north, but probably becoming more unsettled from the southwest, with heavy rain possible at times. Light winds at first but becoming breezy from the southwest. Temperatures generally near or a little above average. Into the latter part of next week and beyond, the most likely scenario is for the unsettled conditions to migrate towards the northwest of the UK, with the best of the drier and warmer conditions towards the southeast.

UK Outlook for Tuesday 16 Sep 2014 to Tuesday 30 Sep 2014:

During mid to late September most regions can expect to see periods of fine weather, with some warm sunshine at times. However, these fine periods may well be interspersed with occasional spells of cloudier, more unsettled conditions bringing showers or longer spells of rain. Northern and western parts are probably most likely to see the more frequent bouts of unsettled weather, whilst southern and eastern parts should see the better fine and dry spells. Daytime temperatures are likely to be above average during fine weather leaving conditions feeling pleasantly warm. Nights, however, may well be on the chilly side. During any unsettled weather daytime temperatures are more likely to be near or below average leaving conditions feeling cool.

Cardiff weather

Cardiff was named capital city of Wales in 1955 and with population of around 350,000, Cardiff is the 10th largest UK city.

The city has a long and varied history, with evidence suggesting the existence of settlers in the area around 1,500 years before the building of Stonehenge. Cardiff's easy access to the coal fields of South Wales has played a large part in its history and demand for coal, used for manufacturing iron and steel, led to Cardiff becoming the world's largest coal port. Since then, the economy of Cardiff has diversified into a range of industries. Cardiff is now the largest media centre outside of London and is the home of BBC Wales, ITV Wales and S4C.

A close proximity to the sea has a moderating influence on temperatures in Cardiff and during winter they can be among the highest in the UK. The minimum average daytime temperature is 2.1 °C. This is for the month of February, when UK minimums are around 0.7 °C. Rainfall is much higher in December and January than February.

Temperatures start to become fairly pleasant from April and in spring the chance of an air frost is much less in Cardiff than other locations in the UK. March sees a few more days of rainfall greater than 1 mm than February but this number falls as we head into April. Spring is the driest season in Cardiff, with rainfall accumulation around 230mm. There is a notable jump in sunshine hours from March to April; both more than the UK average.

Cardiff's hottest temperatures are usually seen in July, with daytime maxima for this month at 21.7 °C - although August is very close at 21.5 °C. July also has the highest average sunshine hours of any month. Rainfall is around the same as the UK average during summer in Cardiff and august often receives the most. In Cardiff thunder occurs on an average of 11 days a year, compared with 15 to 20 days at many places in England.

September and even October cling on to mild temperatures in Cardiff with the average high in the former approaching 19 °C. Sunshine hours are still quite high in early autumn but in October rainfall does start to significantly increase. Overall autumn is the wettest time in Cardiff, with more 'rain days' than any other season and a higher rainfall accumulation.
