The recent spell of hot weather experienced in Adelaide was of a mild nature when compared with many which preceded it. The last succession of high temperatures was really unworthy of notice when the heat waves which lingered over South Australia in 1858 and 1868 are considered.
The records for the last 50 years show that during the summer-November to March Adelaide may expect to have, on the average, five days whose temperatures is over 105 deg. in the shade. In 1867-8 there were 19 such days. There were 17 days over 105 deg. in the summer of 1897-8. Two years later there were 12 days in the summer as hot as those previously mentioned, and in
1865-6 the number was 14.
The longest succession of days whose shade temperatures were over 105 deg. that has been ex-
perienced in Adelaide was in January, 1858, when for eight days the temperature ranged from 107.1 deg. to 116.3 deg. In February, 1866, there were six successive days in which the shade record varied from 106 deg. to 108.5 deg., and in December, 1897, the temperature ranged from 105.8 deg. to 110.8 deg. for five days following.
Four successive days, with the shade over 105 deg., were experienced in each of the following
months:-January, 1867; February, 1859; December, 1898; January, 1905; and January, 1906.
