Winter 2022-23 saw average temperatures overall, with a cold December and mild February. It was a dry winter, particularly in the south, and very sunny in England and Wales, particularly in the east; it was the third suniest on record (since 1919). Temperatures remained low in England Wales though; we have to go back to 1986 to find a year with a worse absence of early warmth.

January. The month of January 2023 had a very mild and wet first half, colder and drier second half, resulting in close to average temperatures overall nearly everywhere. It was particularly cold in parts of Scotland midmonth. The highest temperature of the month was 15.8 at Dyce (Aberdeenshire) on the 24th, and the lowest -10.4 at Drumnadrochit on the 19th. Overall rainfall was about average at 103% of the long-term average across the UK, although much of the rain fell in the first couple of weeks. It was wetter in the west, and drier in the northease. 100.2 mm of rain fell at Maerdy Water Works (Mid-Glamorgan( on the observering day 11-12th. It was a very sunny month, being the second sunniest for England (just behind the exceptionally 2022) and third sunniest for the UK overall (also behind 1919), at 133%, but it was quite dull in NW Scotland. The deepest sn ow depth was 34 cm at Loch Glascarnoch on the 18-18th. There was a marked absence of very windy days, with no named storm.

February. Very mild, very dry, and very anticyclonic, with just a few cooler unsettled interludes. On Sunday 5th the pressure was widely around 1048 mbar, the highest February pressure for 60 years. It was particularly mild in Scotland and Northern Ireland. The CET (average temperature) was 6.5 C (+2.7), although 2019 and 2022 were both even milder, and for the UK as a whole it was the joint fifth mildest February on record. Only NW Scotland saw more rain than average, with much of central and southern England and eastern Wales seeing less than 20% of the long-term average; overall the UK had 48% of the long-term average rainfall, but it was the driest February for 30 years in England (since 1993), and its eighth driest on record (since 1836). Essex saw only an average of 3.5 mm of rain in the month. It was an average month for sunshine (98%), although it was sunnier than average in central and eastern England. The highest temperature of the month was 17.2 at Pershore (Worcs.) on the 17th, and the minimum -8.5 at Tulloch Bridge (Highland) on the 27th. The wettest day was the 3rd, and there was some snow in parts of Scotland on the 18th. There was a stunning auroral display ("the Northern Lights") visible across much of Britain in the early night of Sunday 26th.

March. The wettest March in England and Wales since 1981, with on average twice the average rainfall. It was less however a dry month in the Scottish Higlands and Islands. The UK overall had 155% of the long-term precipitation average, making it the sixth wettest in records dating back to 1836. Sunshine was variable; most areas were dull, and very dull in Wales and southern England, with some places seeing just half the average sunshine, making it locally (Devon, Somerset, Wiltshire, and Hampshire) the dullest since recrds began in their modern form in 1910. It was though sunnier than usual in western Scotland. Overall temperatures were about average, although it was colder in Scotland, with the cold air rarely very far away. The month started very cold but quite dry. The cold spell was widely forecast following an episode of sudden stratospheric warming, although the weather wasn't quite as extreme as other severe cold snaps: it was more of a "Nasty from the North" than a "Beast from the East". On the night of the 7-8th the temperature fell to -15.4 at Kinbrace (Sutherland), the lowest March temperature since 2010. The night of the 8-9th was even colder, with Altnaharra recording -16.0. The 9th saw heavy snow, with drifting, causing disruption particularly across North Wales, the NW, the north, the Pennines, and Northern Ireland, as a rain-bearing front between the mild air to the south and the very cold air to the north moved across the country. The maximum snow depth of the month was 32 cm at Buxton on the 10th. From the 9th it was mild and much more unsettled. The highest temperature of the month was 17.8 ºC at Sanron Downham (Norfolk) on the 30th, and the lowest was the -16.0 at Altnaharra on the 9th. It was the lowest March maximum since 2018. 118.6 mm of rain fell at Honister Pass in Cumbria on the rain day 12-13th.

April. An unsettled month, with temperatures overall close to average (-0.1). It was very wet, dull, and rather cool in the southeast, being particularly wet in Kent, but dry and sunny in the northwest, particularly in the Scottish Highlands. Overall though rainfall was close to average across the country (97%), as was sunshine (102%), all going to show that you must consider regional variations when looking at weather averages in Britain. The highest temperature of the month was 21.2 ºC at Kinlochewe (Ross & Cromarty) on the 17th; the lowest -7.4 at Tulloch Bridge on the 25th and also Loch Glascarnoch on the 26th. The highest rainfall total in one recording day was 54.6 mm at Seathwaite (Cumbria) on the 11-2th. April 2023 around the world: there was a notable heatwave across Spain, Portugal, and Morocco, with 38.8 C recorded at Cordoba airport, Spain, on the 27th, setting a new record high for April in Europe.
