A very long spell with no rain
My town, Manilla NSW, may be having one of the longest periods without rain in 133 years. We will never know.
The records of the Manilla Post Office rain gauge, No. 055031, show that the longest periods without rain were as follows:
1. August 1946: 62 days;
2. April 1912: 55 days;
3. Apr-May 2002: 47 days;
4. August 1914: 46 days;
5. May 1927: 45 days;
6. Mar-Apr 1980: 44 days;
7. April 1925: 43 days;
8. August 1982: 42 days;
9=. March 1896: 41 days;
9=. August 1995: 41 days;
To judge by my rain gauge, we have had a rainless period that is already equal seventh longest since 1883. Today, rain bands are passing through, but perhaps no rain will fall in my gauge. There may be several rainless days yet.
My gauge not valid for Manilla
The photo shows my personal rain gauge. It is dusty because it has been dry for the last 43 days.
Whether it rains in my gauge today or not, my reading cannot count in the record for the town of Manilla. It is as if it is this dry spell is not happening.
My gauge is very simple and not precise. It is hard to read to parts of a millimetre. I bought a cheap one, because there is no point in having a precise rain gauge in my yard. The yard is too sheltered to meet the Bureau of Meteorology standard. My house is also a kilometre away from the Post Office.
Manilla’s failed rainfall record
Rainfall was first recorded at the Manilla Post Office in March 1883. The record of readings was essentially unbroken through 132 years until the 26th of March 2015. There are towns with longer rainfall records, but not very many.
