High weekly temperature persisted only a few days into February. After that, the temperature was normal or below normal. Day temperatures varied, without reaching extremes. Although the warmest February night (27.6°) came on the 2nd, most nights were near normal (18.0°).
After the first days, the dew point was high, making for very humid mornings, which were also overcast.
There were fourteen rain days, over twice the usual number.
Two days had over 40 mm of rain, causing local erosion and flooding. For Manilla, these are not very wet days. [See note below: “Very Wet Days”.]
Comparing February months
The mean monthly temperature, at 25.2°, is near normal, and cooler than the last four February months. More dramatic is the low mean daily maximum temperature (31.1°), which is fourth coolest for February in the new century.
All moisture indicators were extremely high. Compared to 21st century February values, they were:
Cloudy days percent (62%): highest.
Daily temperature range (11.9°): lowest.
Dew point (16.7°): 2nd highest.
Rainfall total (165.4 mm): 2nd highest.
The rainfall total of 165.4 mm is at the 92nd percentile for February, well above the average of 67 mm. The previous eight months all had rainfall below average.
I will report separately on the on-going drought that has again broken a low-rainfall record for a duration of 96-months.
Very Wet Days
I have a blog post that shows the 125 rain days at Manilla that exceeded 50 mm.
From time to time, there is a period of years without extreme daily rainfalls: when no day has more than 80 mm of rain. We are in the longest such period, beginning 21 years ago, on 7 September 1998. [That day was the 5th wettest, at 112 mm, which filled Split Rock Dam.] See the “Comments” section in the linked post.
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. Unfortunately, the gauge failed during this month (25/02/2020 ). Pending repair, I am using my own gauge.
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.
