Senna coronilloides

Spring was marked by a succession of warm and cool spells. Nights varied around the normal seasonal temperature but days had no spells cooler than normal. A hot spell late in November had days 6° above normal as a weekly average. The dew point showed very dry air in mid-November.
There were nine rain days, as in the droughty spring of 2002. The highest reading was 16.6 mm. Rainy and cloudy days came about every three weeks.

The hot dry climate this spring was very like that of 2014, and quite unlike the cool wet climate of 2016.
Days, averaging 29.0°, were hotter than in any spring except 2002 (29.2°). Nights, at 11.2°, were only half a degree above average. (The winter of 2019 had a similar pattern.)
Dryness was shown by very little morning cloud (21%), very low early-morning dew point (3.7°) and very wide daily temperature range (17.8°).
The total rainfall of 62.4 mm makes this the fourth driest spring, after 1957 (23 mm), 1944 (40 mm), and 1951 (54 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. I have used it since 20 July, when the Museum gauge began recording again. My estimates of early morning dew point have become anomalously low. From 1 August 2019, I use values taken from Tamworth Airport graphs at the time of minimum temperature.
All other data, including subsoil at 750 mm, are from 3 Monash Street, Manilla.
