Weather log for July 2020
Repeating the pattern of June, the second week of July was 3° above normal. Again, one night (11th) was remarkably high above normal (9.8°). The final week was also warm.
There were 14 frosts (normally 17), but the number of cloudless days (5) was equal lowest for July.
Seven days registered rain above 0.2 mm, the highest being 10.4 mm on the 27th.
Comparing July months
The mean monthly temperature of 11.1° was the same as last year: only 0.3° lower than the warmest July (11.4° in 2013). However, days were rather cool (18.0°), while nights (4.3°) were the 2nd warmest for July. The resulting daily temperature range of 13.7° was narrower than normal. That suggests humidity, agreeing with a high dew point (3.2°) and cloudiness (39%).
The rainfall total of 31.3 mm, being at the 44th percentile, is still well below the July average (41 mm). However, no July rainfall has been much higher at Manilla in eight years (91.4 mm in 2012).
I will report separately on the on-going drought, that still breaks low-rainfall records.
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.
