The highest temperature recorded during the month was 16.5 Celsius (62F) on the 18th, but there were 4 other days with maxima above 13 Celsius (55F), including a high of 14.2 Celsius (58F) on  the 15th, and 13.8 Celsius (57F) on the 16th.  A further 18 days had highs between 10 and 13 Celsius (50-55F). No  cold days occurred during February, but the maximum on the 7th was only 7.1 Celsius (45F), and 5 consecutive days, beginning on the 23rd, had highs under 10 Celsius (50F). However, none of these days were particularly cool, with the lowest maximum of 8.4 Celsius (46F). This occurred on the 25th.   

Many mild nights occurred during February, and on 4 occasions the temperature stayed above 10 Celsius (50F).  The minimum  on the 18th was 10.9 Celsius (52F), with 10.8 Celsius (51F) on the 15th, and 10.4 Celsius (51F) on the 14th. A further 7 nights had lows between 9 and 10 Celsius (48-50F). All other minima ranged between 4 and 9 Celsius (39-48F) with just 4 exceptions. The 12th had a low of 1.6 Celsius (35F), and the 27th had a minimum of 1.7 Celsius (35F), but the coldest nights of the month were the 24th and 25th, when the temperature dipped to minus 0.6 Celsius (31F) and minus 0.9 Celsius (30F) respectively.   

The sea temperature was 8 or 9 Celsius (46-48F) throughout the month.

There were  2 air frosts during February, and that was 3 below average.

Rain

 

Rainfall in February amounted to 188.0 millimetres (7.4 ins.),  which was over 3 times the monthly average. It was the wettest February in the area since before 1880.  Measurable rain fell on 20 days, which was 4 days above the average, and  wet days (when 1 millimetre (0.04 ins.), or more, of rain falls) numbered 16, which was 6 days above the average. No measurable rain fell on the first 4 days of the month, and this included the only 2 completely dry days, the 3rd and 4th. All other days had a minimum of a trace of rain (less than 0.05 millimetres). The first wet day was the 6th, when 17.2 millimetres (0.68 ins.) of rain fell. This was followed by 12.2 millimetres (0.48 ins.) and 18.4 millimetres (0.72 ins.) on the 7th and 8th respectively. Long periods of rain and drizzle gave 9.0 millimetres (0.35 ins.) on the 13th, and a further 13.0 millimetres (0.51 ins.) on the 14th. High pressure then developed and the barometric reading on the 17th was above 1030 millibars. Remarkably, however, this was the wettest day of the month with 31.4 millimetres (1.24 ins.) of rain falling. Pressure fell rapidly between the 20th and 21st, and both the 21st and 22nd were wet with 10.8 millimetres (0.43 ins.) and 13.2 millimetres (0.52 ins.) respectively. Wet weather on the afternoon  and evening of the 25th was followed by a wet night, and the total for the rainfall day (09-09 GMT) was 30.6 millimetres (1.2 ins.).

The first week of the month and the last 10 days of the month were windy at times, although no especially windy days occurred. At Shoreham Airport,  westerly winds gusted to 31 knots (35 mph) in the early hours of the 5th, with brisk winds continuing through the 6th and peaking at 33 knots (38 mph) from the southwest in the late evening.

The first day of the month was dry,  but precipitation  commenced on the evening of the 2nd and continued, almost without break, until the afternoon of the 5th. Daily rainfall totals included 3.6 millimetres (0.14 ins.) on the 2nd, 30.6 millimetres (1.2 ins.) on the 3rd and 7.6 millimetres (0.3 ins.) on the 4th.

That was more than 30% above the long-term annual average.  The year included 6 months with totals exceeding 100 millimetres (4 ins. ) per month, including each of the last 3 months of the year, which yielded a combined total of 563.6 millimetres (22.2 ins.) of rain.
