rent be not commonly found at the surface in
Bass' Strait, it is not lost. Navigators find it running with
considerable strength, when passing the strait two or three degrees to
the east of Furneaux's Islands; and it was this current so found, which
led admiral Hunter to the first opinion of the existence of an opening
between New South Wales and Van Diemen's Land.
Every thing in Bass' Strait bespeaks the strongest winds to come from the
south-west; and there is reason to believe that during nine months of the
year, it generally blows from some point in the western quarter. In
January, February, and March, eastern winds with fine weather seem to be
not uncommon; but there is no dependence to be had on them at any other
season. At the eastern side of the strait and of Van Diemen's Land, it is
not unusual to meet a north-east or north wind, though it seldom blows
strong. The gales usually come from between south-west and south-east,
and most frequently from the latter direction; which renders it hazardous
to approach the coast between Cape Howe and Wilson's Promontory.
Thus, speaking generally of the south coast of Terra Australis, it may be
considered that during the six or eight winter months, the winds blow
almost constantly from some western point; and that gales of wind at
south-west are frequent. The progress of the gales is usually this: the
barometer falls to 291/2 inches, or lower, and the wind rises from the
north-westward with thick weather, and commonly with rain; it veers
gradually to the west, increasing in strength, and the weather begins to
clear up so soon as it has got to the southward of that point; at
south-west the gale blows hardest, and the barometer rises; and by the
time the wind gets to south or south-south-east, it becomes moderate, the
weather is fine, and the barometer above 30 inches. Sometimes the wind
may return back to west, or something northward, with a fall in the
mercury, and diminish in strength, or die away; but the gale is not over,
although a cessation of a day or two may take place. In some cases, the
wind flies round suddenly from north-west to south-west; and the rainy,
thick weather then continues a longer time.
Such is the usual course of the gales along the South Coast and in Bass'
Strait; but on the east side of the strait the winds partake of the
nature of those on the East Coast, where the gale often blows hardest
between south and south-east. and is accompanied with t
