Outlook for the UK over the next 6-30 days

UK Outlook for Sunday 28 Aug 2016 to Tuesday 6 Sep 2016:

Sunday looks set to be very warm with some sunshine across England and Wales, but with the risk of heavy and potentially thundery showers breaking out during the day. In contrast, Scotland and Northern Ireland are more likely to be cloudier and cooler with spells of rain. Bank Holiday Monday is expected to be often dry and bright with some sunshine, though still with a scattering of showers around - particularly across northern and eastern areas. For the rest of the period, it looks as if it will be rather changeable, with spells of wet and breezy weather at times. The unsettled conditions probably most dominant in the north, with comparatively more in the way of warm and fine weather for the south.

Updated at: 1244 on Tue 23 Aug 2016

UK Outlook for Wednesday 7 Sep 2016 to Wednesday 21 Sep 2016:

A flow of air from the Atlantic between high pressure to south and low pressure to the north looks the most likely weather pattern at this stage, giving rather changeable conditions. The weather probably most unsettled towards the northwest of the country, and most settled towards the southeast. With this regime, temperatures are expected to be near normal for September, though probably warmer than average at times 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.
