Cold. Hot. Wet.
Manila 72 degrees 87 degrees 84 degrees

Seasons vary with the prevailing winds (monsoons or trade winds) and
are classed as "wet" and "dry." There is no abrupt change from one to
the other, and between periods there are intervals of variable weather.

The Spanish description of seasons is as follows:

Seis meses de lodo--six months of mud.
Seis meses de polvo--six months of dust.
Seis meses de todo--six months of everything.

The northern islands lie in the track of the typhoons which, developing
in the Pacific, sweep over the China Sea from NE. to SW. during the
southwest monsoon. They may be looked for at any time between May and
November, but it is during the months of July, August, and September
that they are most frequent. Early in the season the northern region
feels the greatest force, but as the season advances the typhoon
gradually works southward and the dangerous time at Manila is about
the end of October and the beginning of November. Typhoons rarely,
if ever, pass south of 9 degrees N. latitude. Sometimes the typhoon is
of large diameter and travels slowly, so far as progressive movement is
concerned; at others it is of smaller dimensions, and both the circular
and progressive motions are more rapid. However they are always storms
