Outlook for the UK over the next 6-30 days

UK Outlook for Friday 4 Sep 2015 to Sunday 13 Sep 2015:

The gradual change to more settled conditions across the UK continues with plenty of dry and bright weather across much of the UK through the weekend, however there may still be the odd shower around at first, especially towards the east and southeast. The mostly fine and dry weather is expected to continue through until the middle of September, however there is a risk that more unsettled conditions, with spells of rain, could push into southeastern parts early next week. Temperatures on the whole will be slightly below average, although it will feel pleasantly warm in the sunny spells and light winds. Overnight temperatures throughout the period are likely to be on the chilly side, with a risk of localised rural ground frost and fog patches, mainly in the north.

UK Outlook for Monday 14 Sep 2015 to Monday 28 Sep 2015:

Generally settled and fine conditions are expected to develop across Southern parts of the UK later in September, with plenty of dry and sunny weather, with perhaps only a few short lived spells of cloud and rain. In contrast it is likely to become unsettled in the Northwest later in the month, with occasional bouts of rain and strong winds likely. Areas inbetween are likely to see mixed conditions with brighter drier conditions interspersed with some periods of rain and breezy winds. Temperatures will generally be around average in most parts, but feeling warm under any prolonged sunny periods by day, with some chilly nights in the North.

Southampton information

Southampton has long been established as one of the UK's foremost ports. Whilst today's docks may be best known for departing cruise liners, the city has played a major part in maritime history. Southampton was the city that first saw the departure of the Mayflower in 1620 and, in 1912, Southampton was the starting point for the RMS Titanic on its maiden voyage.

The Southampton boat show is also held annually in the city and is a key event in the maritime calendar.

The city has a proud sporting culture, with Southampton Football Club playing at the St Mary's Stadium. The Rose Bowl, home to Hampshire Cricket Club, also hosts regular international cricket.

Generally Southampton has mild winters. The average minimum temperature only falls as low as 2.6 °C in February; which is the coldest month of the year. This is mainly as a result of its close proximity to the sea. Likewise February also has the maximum number of air frost days, though notably lower than the UK average. The highest number of days with rainfall more than 1mm are in January - and winter has more than any other season. Despite this, rainfall accumulation is higher in autumn.

Temperatures can be mild from March onwards, with long term highs of 11 °C. By May, this figure rises to 17 °C. Costal locations can be affected by sea breezes, which result in lower maximum temperatures than further inland. Sunshine hours increases significantly in April from the previous month, and the figure is much higher than the UK average. Rainfall in Southampton is lower in spring than nationally, with May the driest month in the season.

July is the hottest month in Southampton and August is close behind. Average daytime maxima are 22.4 °C and 22.3 °C respectively. Extreme maximum temperatures can occur in either month and are usually associated with heat waves lasting several days. The highest temperature ever recorded in Southampton was 35.6 °C on 28th June. There are more sunshine hours in summer than any other season. Rainfall averages in Southampton during summer are half the national average and the driest month of the year is July, with an average of only 42 mm of rain.

Temperatures usually stay warm in September with an average daytime maximum of 19.8 °C. This is around 3 °C higher than the UK average. Rainfall accumulation in Southampton is highest in Autumn compared to any other season and typically the most rain falls in November. Days of air frost are around 1 day every two years in October, but the likelihood increases dramatically in November.
