NSW Central Coast cops seven-week soaking

Ben Domensino, Tuesday May 21, 2024 - 14:39 AEST


Parts of the Central Coast region in NSW have received more than half a year’s worth of rain in the last seven weeks.


Australia’s 10th most populated urban area, located about one hour north of Sydney and to the south of Newcastle, has been very wet since the start of April.


While Sydney has received about 400 mm over the past seven weeks, some areas on the Central Coast have picked up 700 mm over the same period.


This sustained spell of wet weather has been caused by relentless onshore winds interacting with a series of low pressure troughs and the relatively hilly terrain of the Central Coast region.


The shape and orientation of the coastline also makes the Central Coast a bit more susceptible to rain than Sydney in southerly winds, which has been a frequent wind direction along the NSW coast in recent weeks.

Some of the standout totals in the Central Coast region between 9am April 1 and 9am May 21, a period of 51 days, include:




710 mm at Norah Head, more than half its annual average of about 1170 mm


617 mm at Swansea, about half the annual average


550 mm* at Gosford, about double the April-May long-term average




*Gosford is missing some rain observations in May and may have received about 30 mm more rain than stated in this article.


In Gosford, only four of the first 21 days in May have been completely dry and the suburb is already having its wettest May in 20 years.


Like many areas in eastern NSW, this prolonged run of wet weather has left the ground laden with water and caused the Central Coast Council to close sport grounds across the region on numerous occasions.

Looking ahead, showers are likely to clear the Central Coast from Wednesday and while there is a chance of some wet weather on the weekend, it’s not looking heavy at this stage.
