Highs of 12°C and lows of 4°C. Even at midday it stayed cool enough to want a jacket. 7 rain days in a typical December: noticeable, but most days stayed dry. Most years sat near the average of 7, though 2017 dipped to 2 and 2018 climbed to 9.

The month opened with 10.0 hours of daylight and closed with 9.9. Dusk came early. Nights dropped below 0°C on 2 days of the month on average, so early-morning paths could be icy. Cold snaps happened: the record low for December was −2.1°C, set in 2024.
