Eastern NSW has had one of its wettest summers in years, with more rain moving north through the state today.
The Mid North Coast was the wettest district with Coffs Harbour and Mt Seaview both receiving their wettest summer in more than half a century. Mt Seaview gained 1797mm which is almost three times the summer average and the wettest on record. A bit further south, Forster had its wettest summer in 42 years.
Sydney was also very wet with 348.8mm across 36 days, which is more than 50mm above the summer average. This made it Sydney's wettest summer in five years. More than 80% of this rainfall fell in the last 33 days of summer. Before this burst of rainfall to finish the season, Sydney experienced its hottest day on record and its driest December in eight years.
Other notable summer totals were along the Central Coast with Gosford and Newcastle both notching up their wettest summer in five years with almost double the average summer total.
It was a wetter than usual summer in eastern NSW due to a few major events that brought large totals, including the low pressure system that drenched the coast last weekend. It was a summer with long and hot dry spells at the start followed by brief and strong downpours later in the season.
Today, a low pressure trough is moving north through New South Wales, bringing rain and a cooler southerly change. The change reached Sydney around 2pm, dropping temperatures slightly and bringing the start of the rainfall. Sydney Airport dropped 10 degrees in under an hour.
Sydney can expect rain to develop into the evening before becoming heavy at times overnight. The rain will then begin easing during the middle of the day tomorrow. A similar story is expected along the New South Wales coast with the rain arriving later further north. Showers are expected to linger across the weekend for most of the coast, however there will be sunny breaks, particularly in the south.
