Split Rock Reservoir 4-5-19

A warm spell in the third week was 4.2° above normal. There were 29 days over 25°, many more than usual. Anzac Day (25th) was sunny, calm and warm. It reached 28.2°, which was four degrees above average for that day, but not up to the 28.7° of Anzac Day 2002.
There were no rain days (usually four) and the dew point on the 28th reached a record low April value of minus 3.2°. There were no frosts.

Comparing April months

This month was warm (average 19.8°), but not as warm as April 2018, 2016 or 2005. The mean daily maximum of 27.8° was well below that of April 2005 (29.5°).
There was no rain, as in April 1912, 1925, 1942 and 1971. Dry air was shown by early morning readings of low dew point (5.8°) and very low relative humidity (67%). However, normal moisture was shown by 30% cloudy days and a daily temperature range of 15.9°.

Drought

The on-going unprecedented drought is reported in another 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.  Since no 9 am readings have been recorded since August, I have substituted my non-standard gauge readings for all days.
All other data, including subsoil at 750 mm, are from 3 Monash Street, Manilla.
