Remaining mild and windy with local coastal gales likely. Patchy rain will become increasingly persistent, and heavy at times, particularly over the hills in the north and west. Minimum Temperature 8C.

Updated at: 0405 on Sun 21 Dec 2014

UK forecast for the next 5 days

Updated at: 0221 on Sun 21 Dec 2014

Outlook for the UK over the next 6-30 days

UK Outlook for Thursday 25 Dec 2014 to Saturday 3 Jan 2015:

Largely fine, bright and cold on Christmas Day with many places starting with a frost. Across northern parts there will be some wintry showers, these most likely across northern Scotland. Showers will ease later with a widespread frost overnight, leading to a cold and bright day for many on Boxing Day. However, northern/northwestern parts will become increasingly unsettled with rain, perhaps transient snow, and strong winds developing; risk of gales/severe gales. Into the weekend, low pressure looks likely to become established over the UK bringing periods of rain/showers along with potentially very strong winds. There will also be the risk of some snow, most likely in the north. Into the following week, the most likely solution is for periods of frontal rain and milder temperatures interspersed by colder, showery conditions.

UK Outlook for Sunday 4 Jan 2015 to Sunday 18 Jan 2015:

The most likely scenario for the coming New Year is for a continuation of changeable, and at times, windy weather coming from the Atlantic with the wettest weather probably across western parts of the UK, and eastern parts most likely to see the best of any dry weather. In between the wetter periods there should be drier, brighter, and colder spells. Temperatures are most likely to be around, or slightly below, average for the time of year with overnight frosts and some snow expected, particularly over the high ground.

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.
