Notes:

† Mean of 24 hourly values.
To reduce barometer to gravity of 45° latitude a constant correction of −0.055 has been applied.
Days of gales means days during some hour of which the wind velocity reached or exceeded 40 miles per hour (by Beckley anemograph, factor 3).
In the year 1916 there were no days of snow, hail, or calm.
