Updated at: 0238 on Mon 27 Jun 2016

Outlook for the UK over the next 6-30 days

UK Outlook for Friday 1 Jul 2016 to Sunday 10 Jul 2016:

The changeable and often unsettled weather is likely to continue across most parts through this period. Bands of rain are expected to push eastwards across the country, these interspersed with drier and brighter periods, but also some showers, perhaps some heavy ones at times. The wettest weather is always more likely in the north and west where it will occasionally be windy too, whilst the south and east will see the best of any drier spells along with generally lighter winds. Temperatures on the whole are expected to be near, or somewhat below average for the time of year, but feeling cool more generally in the northwest in any wetter and winder spells. Conversely, it will feel warm in any drier and sunnier periods, especially in the south and east.

Updated at: 1227 on Sun 26 Jun 2016

UK Outlook for Monday 11 Jul 2016 to Monday 25 Jul 2016:

Further changeable conditions are likely to persist at first with rain or showers across many areas, particularly the north and west, and temperatures near average. Around the middle of July there is a possibility of a more settled spell of weather to develop, potentially bringing longer dry periods to much of the country. With this change there would most likely be more in the way of sunshine with some locally warm temperatures and lighter winds. However there is also the possibility of more humid continental air moving up across the southeast at times, bringing a risk of some thundery showers here.

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.
