Weather log for August 2020
In August 2020, both the second and third weeks had warm nights that raised the weekly temperatures. The night of the 15th was especially warm, above normal by 8.5°. With the warm nights most days were cloudy, and five days had more than 0.2 mm of rain. The highest reading, 17.6 mm, was on the 8th.
There were 11 frosts (normally 15).
Comparing August months
The last three August months have all had very low moisture values, with August 2019 being also very warm. This month was much more humid: a higher dew point (2.0°), cloudy skies (42%) and an extremely narrow daily temperature range (12.3°) that was 4° narrower than normal.
Rainfall, however, was only at the 38th percentile (27.8 mm). That is still far below the August average (40 mm) and has added little to depleted water storages.
I will report separately on the on-going drought. Extreme rainfall shortages persist.
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. Recording resumed on 20 July 2019. The gauge failed again during February (25/02/2020 ), but was repaired on 11/3/20.
My estimates of early morning dew point have drifted anomalously low. From August 2019, I use data from the Tamworth Airport published graphs.
All other data, including subsoil at 750 mm, are from 3 Monash Street, Manilla.
