This season had a series of warm spells separated by normal autumn temperatures. The warmest, about 4° above normal, came in early March, late April and late May. Dry air came at cooler times, near the 1st of March and the 12th of April. Most of the rain came in two very wet days: the 30th of March and the 4th of May (61 mm).
Comparing autumn seasons
As in 2018 and 2016, autumn was very warm. Although autumn 2016 had the highest mean temperature of the new century, this autumn had the warmest nights: 12.7°.
Despite the on-going drought, measures of moisture were near normal for the season. Cloudy days reached 37%, the daily temperature range (14.3°) was quite narrow, and the early morning dew point (7.2°) not low. The rainfall total, 117 mm (est.), was at the median value, not far below the mean of 134 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 autumn. I used my own readings for the whole season.
All other data, including subsoil at 750 mm, are from 3 Monash Street, Manilla.
