UK forecast for the next 5 days

Rain and gusty winds crossing southern parts. Showers further north.

Outlook for the UK over the next 6-30 days

UK Outlook for Tuesday 2 Jun 2015 to Thursday 11 Jun 2015:

Rather unsettled and cool conditions across most areas at first, with heavy showers or bands of more persistent rain. Strong winds are also likely, particularly in the south and the northwest. After this, further spells of rain and at times strong winds are expected to affect northern and north-western parts, whilst across the south of the UK conditions become mainly fine and dry. Later in the period, all parts of the UK are set to see some dry weather with periods of sunshine. Temperatures are also likely to recover to become rather warm in the south, with the north also rising to around normal for the time of year. Towards the end of this period, very warm weather may develop in south, albeit accompanied by the threat of heavy showers.

UK Outlook for Friday 12 Jun 2015 to Friday 26 Jun 2015:

High pressure looks to have become established across the north of the UK by the start of this period. This will bring fine and dry conditions to most parts with much warmer conditions than of late across the north. It is also expected to be very warm in the south, although here there is a risk of some heavy and thundery showers spreading up from continental Europe. Confidence in the forecast drops towards the end of June; however, the general trend looks set to remain much the same, meaning drier conditions in the north, some showers possible in the south and warm or very warm temperatures.

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.

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