Outlook for the UK over the next 6-30 days

UK Outlook for Friday 4 Sep 2015 to Sunday 13 Sep 2015:

The gradual change to more settled conditions across the UK continues with plenty of dry and bright weather across much of the UK through the weekend, however there may still be the odd shower around at first, especially towards the east and southeast. The mostly fine and dry weather is expected to continue through until the middle of September, however there is a risk that more unsettled conditions, with spells of rain, could push into southeastern parts early next week. Temperatures on the whole will be slightly below average, although it will feel pleasantly warm in the sunny spells and light winds. Overnight temperatures throughout the period are likely to be on the chilly side, with a risk of localised rural ground frost and fog patches, mainly in the north.

UK Outlook for Monday 14 Sep 2015 to Monday 28 Sep 2015:

Generally settled and fine conditions are expected to develop across Southern parts of the UK later in September, with plenty of dry and sunny weather, with perhaps only a few short lived spells of cloud and rain. In contrast it is likely to become unsettled in the Northwest later in the month, with occasional bouts of rain and strong winds likely. Areas inbetween are likely to see mixed conditions with brighter drier conditions interspersed with some periods of rain and breezy winds. Temperatures will generally be around average in most parts, but feeling warm under any prolonged sunny periods by day, with some chilly nights in the North.

Cardiff information

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 230 mm. 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.
