PPLEMENT,
OF THE METEOROLOGICAL OFFICE, LOND
Mainly dull, rainy and cool, many
A succession of low pressure systems>in the neighbourhood of the
British, Isles >resuited in cloudy, wet weather with average or rather
low temperature over the country throughout the month. There was a
fine interlude over the whole country on the 10th, and over most of
England and Wales also on the 9th, llth and 12th. Only on the 4th in
East and Southeast England did temperature reach 80°F. „ rising to 83°F.
at Camden Square (London), and 82°F. at Tunbridge Wells.
Except locally in Southeast England and East Anglia, especially in
coastal areas »rainf all was above the average. At a number of places
in Wales, North Ireland and Western England over twice the average
amount of rain was measured . At Pembroke there were 8.01 inches,
representing over 3 times the average and a record,(since 1877). At
Sealand and Aldergrove it was also the wettest July on record.
Except for the above mentioned fair interludes, the period 5th till
the 24th was particularly wet, and thunderstorms were frequent and
widespread,though not severe.
Notable daily falls were 3.72 inches
at Troon (Ayrshire) on the 15th, 2.83 inches at Teignmouth , and
2.32 inches at Shrewsbury on the 21st, 2.17 inches at Eskdalemuir on the
28th and 2,2 inches at Tintagel on the 5th. At Ross-on-Wye on the 21st
rain fell for 6 minratea at the rate of over 3.8 inches an hour.
Daily Rainfall at KEW Observatory,
July. 1939- No. 271,
thunderstorms.
Everywhere sunshine i-ecords were below the average. Rosson-Wye reports that only once during the last 25 years has such
a dull July been experienced. Stornoway had 14 days without any
bright sunshine , and this station, together with Aldergrove,
had its dullest July on record.
Even during the fine spell in
England from the 10th to the 12th only moderate amounts of
sunshine were registered, though 16 Hours were enjoyed at
Leuchars, and 15.6 hours at Dunbar and Renfrew on the 10th.
Gaits were infrequent and not severe. They were experienced
locally on the Western Seaboard of Scotland and Ireland on the
14th and 15th, and locally on the Welsh coast on the 28th. In
gusts the wind reached 60 m.p.h. at Pembroke on the 6th.
There was local coast and sea fog in eastern districts
on the 15th, 16th, 19th and 26th, and in Southwestern districts
on the 27th to 29th . On a number of occasions after the 15th
early morning inist or fog occurred locally inland.
