Storm at Dusk

This summer had 7 very hot days above 40°, and 11 very hot nights above 24°.
The worst heat waves came in January. Around the 17th, weekly temperatures were more than 6° above normal, with days at about 41°, and nights 24°. Near the 28th, nights were even warmer. Episodes of very low dew point came at times of lower temperature.
Thirteen rain days were scattered through the season, the highest readings being 25.0 mm on 16 December and 18.0 mm on 21 January.

Comparing summer seasons

Average temperatures were almost the same as in the hot summer of 2016-17. Days, at 35.5°, were slightly cooler and nights, at 20.1°, slightly warmer. The resulting average, 27.8°, was a new record summer temperature, beating 2016-17 by 0.2°.
Remarkably, the mean subsoil temperature, 25.5°, was not high, but normal.
Similarly, daily temperature range (15.4°) and cloudiness (22%) were normal. (Recent summers have been cloudy.) Dryness was shown only by very low humidity and rainfall.
The mean early morning dew point for this summer (10.4°) was second lowest in the 19-year record. Only that of summer 2013-14 (8.6°) was lower.
The total rainfall for the summer, 70 mm, was equal second driest with 1965, the driest summer being 1930, which had 66 mm.

Data. A Bureau of Meteorology automatic rain gauge operates in the museum yard. From 17 March 2017, 9 am daily readings are published as Manilla Museum, Station 55312.  These reports use that rainfall data when it is available. Station 55312 recorded no readings this summer. I used my own readings for the whole season.

All other data, including subsoil at 750 mm, are from 3 Monash Street, Manilla.
