July was fourth wettest, and August is already wetter
The Peninsula's July rainfall total of 116.8mm was the fourth highest July total in 20 years, according to figures supplied by Mr Jim Morrison of Umina.
A fall of 46.9mm on the last day of the month took the total 37.8mm beyond the month's average of 79mm.
Falls totalling 128.3mm in the first week of August already made this month the fourth wettest August in 20 years.
The figure is almost double the average of 65mm.
Rainfall of 28.7mm recorded on Saturday morning and 37.1mm recorded at 9am on Sunday took the total to 194.1mm, within five millimetres of the second wettest August total of 199.8mm recorded in 2019.
It is believed this figure was exceeded with rain during the day yesterday.
The wettest August was in 2014 with 216.6mm recorded.
