Dry and fine for most, with rain continuing in northwest.

Outlook for the UK over the next 6-30 days

UK Outlook for Saturday 27 Sep 2014 to Monday 6 Oct 2014:

Fairly cloudy at first, though some sunny intervals developing for central, southern and eastern parts of the UK. Outbreaks of rain are expected for northern and western areas, more persistent for parts of Scotland and Northern Ireland, although clearer, showery weather should follow for a time. It will be quite windy here too. Temperatures generally near or a little above normal. Into the following week, the north and west are likely to remain the windiest and most unsettled parts of the UK, with the best of the weather further south and east. However, a little rain is to be expected here at times. Temperatures should be a little above normal for most. This general northwest-southeast split in the weather is then likely to continue into the start of October.

UK Outlook for Tuesday 7 Oct 2014 to Tuesday 21 Oct 2014:

The broadly northwest-southeast split in weather conditions expected to become established for late September and early October is then showing signs of persisting into mid-October. This pattern would leave southern, central and eastern parts tending to see the best of the weather with conditions often fine and dry. Occasional bouts of rain should still be expected, and mist and fog patches may be a problem during morning rush hours but under fine weather it should feel pleasant. Further northwest, conditions are likely to be more unsettled with more frequent outbreaks of rain, perhaps accompanied by strong winds, temperatures here then often closer to average or perhaps even just below at times.

Southampton weather

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.

All climate data based on Southampton W.C, 1981 - 2010.
