It was the 5th brightest January on record in the UK but I doubt anyone noticed!\u00a0 Otherwise, the weather was unremarkable.
\n<\/p>\n

The meteorological year starts in December which is why December appears as the 1st data point in the charts below.\u00a0 More information on the layout of the charts can be found in this pos<\/a>t.\u00a0 Points lying between the upper and lower deciles are shown as open black circles, points lying between the lower\/upper deciles and the minimum\/maximum respectively are shown as solid black circles and any month with a new record is shown as solid black squares.\u00a0 All data is supplied by the Met Office and can be found here<\/a>.<\/p>\n

Every month I update 7<\/strong> charts in all.\u00a0 I rotate which 6<\/strong> appear in the deck above and \"\"plot the 7th<\/strong> as a separate chart here.\u00a0 Between November & February, Sunshine (chart G) is shown here since that is of least interest in these months.<\/p>\n

How abnormal was January 2025?<\/strong><\/span><\/h4>\n

\"\"Chart H displays my UK Weather Abnormality Index<\/strong><\/span> (see my May 2019 post for details<\/a>).\u00a0 The closer to zero this index is, the less abnormal and thus more “average<\/em>” a month is.\u00a0 The higher it is, the more abnormal the month is.\u00a0 When the index is over 100%<\/strong>, we can describe the month as unusual in some way.<\/p>\n

The abnormality index was 53% <\/strong>this month which is in line with the median.<\/p>\n

PS: If you bookmark this link<\/a>, it will be refreshed with the latest month’s data.\u00a0 I usually post the update in the first week of each month.<\/em><\/p>\n

Click the relevant month to see what the weather was back then.\u00a0 Months highlighted in bold had an abnormality index exceeding 100% indicating unusual weather.\u00a0 Alternatively click the Weather Tracker<\/a> hash tag below this post to see a list of all such posts.<\/p>\n
