dull, gloomy appearance between that point and South-West.
May is the month in which the winter weather fairly sets in, and it
rarely happens that the middle of this month passes without the rains
having commenced. This season seems to vary but little as to the time and
manner of setting in--it is ushered in by blowing weather, from about
North-North-East, the wind gradually veering round to the westward, as it
increases in strength. The first of this weather usually lasts from a
week to fourteen days; then comes an interval of fine weather, generally
of a fortnight's duration, and sometimes a month; after which the rains
set in more constant, and the intervals of fine weather are shorter; this
weather lasts until October, and at times throughout that month.
During the intervals of fine weather the climate is delightful, and the
country has a fresh and pleasing appearance; land and seabreezes are as
regular as in summer, with the exception, that the latter are much more
moderate.
The North-West gales that occasionally occur during the winter months, on
the southern parts of the west coast of Australia, are probably felt as
far north as Shark's Bay. They blow with great violence, and are
accompanied by dark, gloomy weather, and rain. It is then unsafe to be
near the land--as the gale that commences at North-North-East, invariably
veers to the westward, making a lee shore of the whole line of coast, and
between West-North-West and West-South-West blows the hardest.
Fortunately these gales give ample warning; the barometer always
foretells their approach, and generally begins to fall three or four days
before the commencement of the gale--besides which, there are other
never-failing indications of a northerly wind, such as, the change of the
current, which (owing to the prevailing southerly winds) usually sets to
the northward, but runs strong to the southward during northerly
winds--frequently preceding them, and giving more timely notice than the
barometer.
A rising of the water is likewise a certain prognostic of a northerly
wind; and has been invariably noticed, at Swan River, to precede all
gales from that quarter--this, of course, can only be observed while at
anchor on the coast.
Another, and perhaps equally certain sign of approaching bad weather,
during the winter season (and which is almost certain to be from the
northward) is the strength of the North-East winds--as it has been
