Outlook for the UK over the next 6-30 days

UK Outlook for Sunday 5 Jul 2015 to Tuesday 14 Jul 2015:

Many places will have a dry morning on Sunday, with sunny spells. However, some showers may develop during the afternoon, mainly in the north and the west. Temperatures will generally be near or just above average, though perhaps still very warm in the southeast. From the new working week onwards, there is an increasing risk of some rain spreading into the west and northwest at times, but most places look to stay mainly fine and dry, especially in the far south and southeast. Temperatures will remain near or slightly above average for many, though the very warm and humid conditions could perhaps return to the south and southeast at times, accompanied by some heavy showers or thunderstorms.

UK Outlook for Wednesday 15 Jul 2015 to Wednesday 29 Jul 2015:

Many southern and central parts of the UK are likely to be mainly dry, often with fine, warm conditions. Towards the north and northwest there is more of a risk of seeing spells of more unsettled weather, however any periods of rain may well be less frequent than normal with some good periods of dry weather expected here as well. Temperatures are likely to be near or a little above average in the northwest, but in the southeast it will be very warm for the time of year, and could possibly become hot at times. With these warmer temperatures there is a continued low risk of occasional thundery outbreaks, especially in the southeast.

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.
