The following observations of Sydney’s climate were written at the time of first European settlement…

Watkin Tench 1793:

“….Horticulture has been attended in some places with tolerable success… Nor will this surprise, if the genial influence of the climate be considered. Placed in a latitude where the beams of the sun in the dreariest season are sufficiently powerful for many hours of the day to dispense warmth and nutrition, the progress of vegetation never is at a stand. The different temperatures of Rose Hill (near Parramatta) and Sydney in winter, though only twelve miles apart, afford, however, curious matter of speculation.

… Again, the heats of summer are more violent at the former place than at the latter, and the variations incomparably quicker. The thermometer has been known to alter at Rose Hill, in the course of nine hours, more than 50 degrees (Fahrenheit = 10 degrees Celsius) ; standing a little before sunrise at 50 degrees, and between one and two at more than 100 degrees (= 38 degrees Celsius). To convey an idea of the climate in summer, I shall transcribe from my meteorological journal, accounts of two particular days which were the hottest we ever suffered under at Sydney.

…December 27th 1790. Wind NNW; it felt like the blast of a heated oven, and in proportion as it increased the heat was found to be more intense, the sky hazy, the sun gleaming through at intervals.

At 9 a.m. 85 degrees. At noon 104. Half past twelve 107 ½. From one p.m. until 20 minutes past two 108 ½. At 20 minutes past two 109 (= 42 degrees Celsius). At Sunset 89. At 11 p.m. 78 1/2

[By a large Thermometer made by Ramsden, and graduated on Fahrenheits scale.]

December 28^th 1790.

At 8 a.m. 86 10 a.m. 93 11 a.m. 101 At noon 103 1/2 Half an hour past noon 104 1/2 At one p.m. 102 At 5 p.m. 73 At sunset 69 1/2

[At a quarter past one, it stood at only 89 degrees, having, from a sudden shift of wind, fallen 13 degrees in 15 minutes.]

My observations on this extreme heat, succeeded by so rapid a change, were that of all animals, man seemed to bear it best. Our dogs, pigs and fowls, lay panting in the shade, or were rushing into the water.

But even this heat was judged to be far exceeded in the latter end of the following February, when the north-west wind again set in, and blew with great violence for three days. At Sydney, it fell short by one degree of what I have just recorded: but at Rose Hill, it was allowed, by every person, to surpass all that they had before felt, either there or in any other part of the world. Unluckily they had no thermometer to ascertain its precise height. It must, however, have been intense, from the effects it produced. An immense flight of bats driven before the wind, covered all the trees around the settlement, whence they every moment dropped dead or in a dying state, unable longer to endure the burning state of the atmosphere. Nor did the perroquettes, though tropical birds, bear it better. The ground was strewn with them in the same condition as the bats.

Were I asked the cause of this intolerable heat, I should not hesitate to pronounce that it was occasioned by the wind blowing over immense deserts, which, I doubt not, exist in a north-west direction from Port Jackson, and not from fires kindled by the natives. This remark I feel necessary, as there were methods used by some persons in the colony, both for estimating the degree of heat and for ascertaining the cause of its production, which I deem equally unfair and unphilosophical. The thermometer, whence my observations were constantly made, was hung in the open air in a southern aspect, never reached by the rays of the sun, at the distance of several feet above the ground.

My other remarks on the climate will be short. It is changeable beyond any other I ever heard of; but no phenomena sufficiently accurate to reckon upon, are found to indicate the approach of alteration. Indeed, for the first eighteen months that we lived in the country, changes were supposed to take place more commonly at the quartering of the moon than at other times. But lunar empire afterwards lost its credit. For the last two years and a half of our residing at Port Jackson, its influence was unperceived. Three days together seldom passed without a necessity occurring for lighting a fire in an evening. A habit dete, or a habit de demi saison, would be in the highest degree absurd. Clouds, storms and sunshine pass in rapid succession. Of rain, we found in general not a sufficiency, but torrents of water sometimes fall. Thunder storms, in summer, are common and very tremendous, but they have ceased to alarm, from rarely causing mischief. Sometimes they happen in winter. I have often seen large hailstones fall. Frequent strong breezes from the westward purge the air. These are almost invariably attended with a hard clear sky. The easterly winds, by setting in from the sea, bring thick weather and rain, except in summer, when they become regular sea-breezes.

To sum up: notwithstanding the inconveniences which I have enumerated, I will venture to assert in few words, that no climate hitherto known is more generally salubrious, or affords more days on which those pleasures which depend on the state of the atmosphere can be enjoyed, than that of New South Wales. The winter season is particularly delightful.”
