Rather Mild and Dry
Temperatures
The average maximum temperature during January 2022 in Shoreham was 8.9 Celsius (48F), and that was almost 1 Celsius (1.5F) above normal for the time of year. The average minimum temperature was 3.4 Celsius (38F), and that was very slightly below the January average.
The highest temperature recorded during the month was 13.4 Celsius (56F) on the 1st, but there were several other very mild days. On the 29th, a maximum of 12.9 Celsius (55F) was recorded, and a further 8 days had maxima above 10 Celsius (50F). On many days (12) the temperature rose to between 8 and 10 Celsius (46-50F) but there were some cooler days. However, only 3 days had maxima below 6 Celsius (43F). The 21st and 24th had highs of 5.9 and 5.7 Celsius (43 and 42F) respectively, but the coldest day of the month was the 25th with a maximum temperature of 4.3 Celsius (40F).
There were very few mild nights during January, but on the 1st a minimum of 10.8 Celsius (51F) occurred, and the 2nd was even milder with a low of 11.1 Celsius (52F). Perhaps surprisingly, there were only 5 other nights with minima above 5 Celsius (41F), with just 1 of those milder nights occurring between the 5th and 28th. There were 9 nights with lows between 2 and 4 Celsius (36-39F), but on many nights (12) the minimum was around freezing, with lowest values between minus 1 and plus 2 Celsius (30-36F). The coldest night of the month was the 6th, with a minimum of minus 2.2 Celsius (28F), but minus 1.9 Celsius (28F) occurred on the 18th.
The sea temperature was around 10 Celsius (50F) at first, but for much of the month it stayed close to 9 Celsius (48F), and it was nearer 8 Celsius (46F) during the last week of January.
Frost
A total of 6 air frosts occurred during January, close to the monthly average, but with the exception of the 6th and 18th, the frosts were very slight with minimum temperatures less than 1 degree Celsius (1.8F) below freezing. On 3 consecutive nights, the 13th, 14th and 15th, there was a slight air frost. Grass frost occurred on 16 nights, and that was 4 nights above average. Most of the grass frosts (13) occurred between the 5th and 22nd, including 5 consecutive nights commencing on the 5th, and 3 consecutive nights beginning on the 13th, and again on the 20th. On many nights the grass minimum was not far below freezing, but there were exceptions. On the 18th a low of minus 5.6 Celsius (22F) was recorded, and on the 6th a grass temperature of minus 6.7 Celsius (20F) was measured.
Rain
Rainfall in January amounted to 41.4 millimetres (1.6 ins.), which was around 20% below average for the month. Measurable rain fell on 13 days, which was about 7 days below the average, and wet days (when 1 millimetre (0.04 ins.), or more, of rain falls) numbered 9, and that was close to 5 days under the average. The month began quite wet with 3.6 millimetres (0.1 ins.) measured on the 1st, and a further 7.4 millimetres (0.3 ins.) on the 2nd. After a dry day on the 3rd, another 3.4 millimetres (0.1 ins.) were recorded on the 4th. A dry day on the 5th, was followed by a continuance of the unsettled spell that yielded rain on 5 of the following 6 days. Much of the rain was light, but 5.4 millimetres (0.2 ins.) fell on the 7th, and the 8th proved to be the wettest day of the month with 12.4 millimetres (0.5 ins.) of rain measured. Pressure rose during the 10th, and from the 11th to the 29th, apart from on 15th, the pressure remained above 1030 millibars, and on 4 days it was over 1040 millibars. It resulted in the pressure for the month being 12 millibars above average. As a result, rainfall during the last 3 weeks of January was considerably below average. The weather was not entirely settled, but between the 12th and the end of the month there were only 3.4 millimetres (0.1 ins.) of rain, with only 1 day, the 15th, having over 1 millimetre (0.04 ins.) of rain, and that was a mere 1.2 millimetres (0.05 ins.).

Wind
With high pressure dominating the weather for much of the month, winds were much lighter than normal and, with the centre of high pressure generally to the west of the country, winds were predominantly from a northwesterly direction. Unusually, winds from the ‘prevailing’ southwesterly direction accounted for less than 20% of the daily observations. Southwesterly winds were rare even in the unsettled weather at the beginning of the month, although during that period winds were quite strong at times. At Shoreham Airport, southwesterly winds were quite strong from the afternoon of the 2nd until mid-morning on the 3rd. A gust of 32 knots (36 mph) was recorded in the evening on the 2nd, and a gust of 30 knots (34 mph) occurred mid-morning on the 3rd. North to northwesterly winds gusted to 31 knots (35 mph) early in the afternoon on the 4th, and southwesterly gusts reached 34 knots (39 mph) on the evening of the 6th. Southwesterly winds gusted to 34 knots (39 mph) again on the afternoon of the 8th. No more strong winds occurred until the 31st, when the remnants of ‘Storm Malik’, which caused damage and loss of life in northern Britain and parts of continental Europe, reached southern England. However, although the morning was blustery, the highest gust (from the northwest) was only 38 knots (43 mph).
Fog
The 11th was a very misty day, but the only fog occurred on the morning of the 11th. It was freezing fog, but it lifted and dispersed soon after mid-morning.
