Outlook for the UK over the next 6-30 days

UK Outlook for Monday 30 May 2016 to Wednesday 8 Jun 2016:

Much of the United Kingdom, especially the northwest, will see dry, bright and reasonably warm weather for the end of May. Southeastern areas, however, should be cloudier and cooler, and increasingly likely to see outbreaks of rain, which could turn heavy and thundery and perhaps more prolonged for a time, accompanied by strengthening winds. This pattern of weather looks to continue for the start of June, with showers or longer spells of rain most likely in the east and southeast, with the best of the warmer, drier and brighter weather in the west and northwest. However, there is a signal for the weather to become more generally drier and brighter across the UK towards the end of the period, although there remains a threat of showers in the south.

Updated at: 1234 on Wed 25 May 2016

UK Outlook for Thursday 9 Jun 2016 to Thursday 23 Jun 2016:

Currently it looks likely that generally settled conditions will continue through the start of this period. This means we can expect a good deal of dry and bright weather for many parts of the country, particularly in the north and northwest. There will probably be some wetter intervals mixed in, these most likely in the south, where they could turn thundery at times. Towards mid-to-late June, there is a chance that more unsettled conditions could become established, although the timing and likelihood of this change remains uncertain. Temperatures, on the whole, will probably be slightly above the June average, especially in the west and south.

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.
