Comments on March 2024

Mean air temperature in March was above average for the 8th month in a row. Daytime temperatures were not exceptional: the mean maximum was only just above average and the total of 18 days above 10 °C was just two above the average. Nighttime temperatures were comparatively mild: the mean minimum (4.0 °C) is the sixth highest on record since 1844. Notwithstanding the caveats about daytime temperatures, March proved to be the 16th warmest on record since 1844. The mean grass minimum (2.5 °C) was the equal 4th highest for March (with 1990), exceeded only in 1938 (3.8 °C), 1957 (3.2 °C) and 1960 (2.6 °C).

Rainfall was above average, 125% of the 1991-2020 monthly average. There were 23 rain days, so rainfall was frequent if never exceptionally high on any given day. For the second month in a row, hours of bright sunshine were below average.
