Updated at: 0431 on Tue 21 Apr 2015

Outlook for the UK over the next 6-30 days

UK Outlook for Saturday 25 Apr 2015 to Monday 4 May 2015:

It is likely to be unsettled throughout Saturday and Sunday with spells of showery rain and breezy conditions affecting many regions. During the rest of the period, most areas will be affected by bouts of unsettled weather with showers and longer spells of rain. Some heavy showers are possible, and during the last few days of April, some of the showers may also be wintry over hills. In spite of the rain and showers there should be some brighter periods too. Conditions are also likely to turn cooler than of late during late April, more especially in the north, and this change may happen as early as next weekend. Windy at times too, especially in the north.

UK Outlook for Tuesday 5 May 2015 to Tuesday 19 May 2015:

The unsettled conditions that will become established during late April are likely to persist into early May. Beyond this, there are no strong signals regarding likely weather types. As such, the most likely scenario is for weather conditions during this period to be fairly typical for the time of year with spells of fine and bright weather interspersed with occasional bouts of more unsettled and changeable conditions. Daytime temperatures are likely to be above average when conditions are fine and near or a little below average during unsettled weather. As is common for the time of year, spells of settled weather may be accompanied by chilly evenings with isolated overnight frost in rural areas.

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.
