May.—A very variable month.
Until about the 22nd, cold weather ruled, notably
round the 6th and 7th, when low temperatures were
common; frost in many localities. Suddenly unusual heat
set in, and from the 25th to the 30th day readings of 80°
and upwards were numerous over England, 84° on the
26th and 27th at some London stations. With the heat
came more or less severe thunderstorms to nearly all
parts of England, from the 26th to the 31st, resulting in
a number of casualties. But there were singularly few
heavy rain and hail falls, generally less than A inch. At
Warlingham, on the 27th, there was a sudden drop of
13° in the temperature, on the breaking of a thunderstorm.
The same storm at Southend was noted as the
heaviest for ten years, the hailstones being l¼in. in
diameter.
There was a marked increase in the frequency of
coastal fogs, in the East during the first fortnight, and
in the South and West during the very warm weather at
the end of the month, often dense, and leading to
numerous casualties.
Mean temperatures: Highest, 66 6°; lowest, 45.3°.
Rainfall at Leyton, 1.25 inches.
