October is officially the wettest month of 2018 with the Woy Woy Peninsula recording 228.9mm of rain in the first 18 days of the month, according to rainfall data compiled by Umina’s Mr Jim Morrison.

It’s been a very wet start to the tenth month with rainfall events recorded across 12 of the 18 days at the time of writing. October has also broken the 2018 record for heaviest single rainfall event twice over the past fortnight, with 45.2mm of rain recorded on October 11 and a staggering 76.5mm on October 14.

The previous single rainfall record was 41.5mm on June 27. The total thus far also sets a new rainfall record for October, with Mr Morrison indicating that this year’s falls have been the heaviest the Peninsula has seen in October since he began compiling the region’s rainfall data back in 2005. The average monthly rainfall for October is 56mm.

These results bring the Peninsula’s total rainfall for 2018 up to 791.mm. This is still well below the cumulative average for this time of year, with the October rainfall making up almost a third of the total alone.
