View from the Rear Window - January 2025

 Life imitates art far more than art imitates life - Oscar Wilde

This month's garden photo (Photo 1) was taken on the 5th January 2025 when we experienced a brief period of snowfall. When it wasn't snowing, we enjoyed the weak January sunshine despite the cold temperatures.

Whereas the previous month (December 2024) was mild yet dull, January 2025 was cold yet sunny. January's weather stats from our Davis Weather Station are summarised in the table below ...

In contrast to frost-free December, we experienced subzero temperatures on more than 40% of the days in January (Figure 1). If daytime temperatures hadn't picked up towards the end of the month, we would have been in for a very cold month.

On the bright side, we did see the sun this month (about 20% more than in December) which always heightens the spirits. Rain was largely restricted to the beginning and end of the month (Figure 2) and close to the average for this time of the year. Precipitation on the 5th/6th January fell as snow.

Figure 2: Daily Rainfall & Sunshine Data for January 2025

With six complete years of weather data from the Davis Weather Station, we can start looking for trends. It is still very messy data because of the short period of time but minimum and maximum daily temperatures both seem to be trending downwards albeit the effect on the mean daily temperature is less clear. Interestingly, 2022 had the highest daily mean and maximum temperatures as well as the most air frost (sub zero) days (Figure 3).

Figure 3: January 2025 Temperature Data (2020 - 2025)

January's rainfall was close to the long-term mean following three dry Januarys (2022 - 2024). Sunshine levels have been very constant over the past 6 years with just a little more during this January. Stormwise, January was quiet though we did catch the edge of Storm Eowyn on the 24th of the month (see Table above).
Figure 4: January Rain, Wind & Sunshine Trends (2020 - 2025)

The following three figures are taken from the UK Met Office's Monthly Report for January 2025. December 2024's mean temperature anomaly map for the UK was all red/pink (hot) in complete contrast to this month which is all blue (cold). Herefordshire is marked by the black circle with the city of Hereford falling within the darker blue (colder) region (Figure 5).

Figure 5: UK Mean Temperature Anomalies for January 2025

Precipitation was close to, or slightly above, the long-term average (1991 - 2020) - see Figure 6. Credenhill Weather Station, located less than five miles away, reports the 1991-2020 mean January rainfall at 67.3 mm; this makes the recorded precipitation in our back garden 117% of this long-term average.

Finally, UK sunshine hours are mapped out in Figure 7 with the city of Hereford falling within the 130-150% band. Our Davis Weather Station recorded the highest January sunshine hours for the last 6 years (110%); close but no cigar! Maybe, January has been getting sunnier over the last 30 years.
