OF THE WINDS AND CURRENTS, AND DESCRIPTION OF THE PORTS, ISLANDS, AND COAST BETWEEN PORT JACKSON AND BREAKSEA SPIT.
EAST COAST.
The south-east trade cannot be said to blow home upon that part of the coast of New South Wales, which lies between Breaksea Spit and Port Jackson, except during the summer months when winds from that quarter prevail and often blow very hard; they are then accompanied by heavy rains and very thick weather: generally however from October to April they assume the character of a sea-breeze and, excepting during their suspension by south-easterly or westerly gales, are very regular.

In the month of December strong south-easterly gales are not uncommon; and in February and March they are very frequent.
In the month of December hot winds from the north-west will sometimes last for two or three days, and are almost always suddenly terminated by a gust of wind from the southward.

The most prevailing winds, during all seasons, are from the south, and are probably oftener from the eastward of that point than from the westward.
