Notes

The longitude of the station = 7h 36m 41.86s E. The latitude of the station = 22° 18′ 13.2″ N. H = Height above mean sea level. hr = Height of the rain-gauge above the ground. ht = Height of the thermometers above the ground.

  • 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 1912 there were no days of snow, hail, or calm. For further particulars see "Meteorological Observations made at the Royal Observatory, Hongkong, in the year 1912".
