Summary
Apart from January, which was a cold month, the March to July period has been exceptionally warm. All of the months have had a mean maximum of more that 2 degC above the long term average (1991-2020). The minima in the March-July period are also well above normal.
The most obvious statistic about the first half of 2025 is its lack of rain. This was most prominent in April, and relented a little in July.
