Rainfall on Ochre Arch 2007 and 2008
The attached image shows monthly rainfall on Ochre Arch for 2007 and 2008, together with estimated monthly rainfall based on figures from a neighbour kept over in excess of 45 years.
Actual figures for the years are 2007: 380 mm, 2008 473 mm, long term 600 mm
Some of the key messages are:
1. Rainfall for the past 2 years has been substantially lower than the long term figures. That said, one could well ask the question "Is 45 years really long term"?
2. On 5 out of 12 months in 2007 and 3 out of 12 months in 2008 the monthly rainfall exceeded the long term monthly figure of 50 mm.
3. Yes - it remains dry!
