WEATHER FOR JUNE
For the first time in 56 years tropical cyclones were completely
absent over the South China Sea and western north Pacific during the first six months of the year. ·
The Royal Observatory in its monthly report on the weather said
it was only the fourth time on record that this had occurred, the last
being in 1917. The others were in 1889 and 1897.
A spokesman for the Observatory said that for the month of June
the weather was "near normal" but it was slightly more humid. The monthly mean relative humidity of 87 per cent was the fourth highest on record for
June.
At the beginning of the month, it was mainly fine and hot apart
from a few brief showers. On June 2, a trough across central China moved southwards and caused periods of rain and occasional thunderstorms during the following three days.
The trough passed through Hong Kong on June 6 and prevailing winds
changed from westerly to easterly. On June 7, the easterlies freshened and the minimum temperature of the month, 22.8°C was recorded in the early
morning of June 8.
Unsettled weather persisted over Hong Kong for the following week:
when the trough remained almost stationary over the northern part of the
South China Sea.
