Thunderstorms forecast after two-month Sydney dry spell

Sydney residents had to dust off their umbrellas on Monday morning as the city experienced its first decent rainfall in two months.

The droplets falling from the sky were a novel sight after the driest Sydney September on record.

Weatherzone meteorologist Joel Pippard said more rain would fall throughout the day, with a chance of thunderstorms in Sydney's north and west.

The rain is a welcome relief as gardens and sports ovals have shrivelled over spring.

Rainfall during September was 0.2 millimetres, the lowest possible amount that can be recorded. The average rainfall for Sydney in September is 68.4 millimetres.

The Bureau of Meteorology is forecasting between 5-10 millimetres of rain on Monday, with falls expected to become heavier in the afternoon.

"There is a decent chance of a thunderstorm in the Sydney basin later this afternoon," Mr Pippard said.

"Showers and storms are expected to move through the northern half of Sydney and the western suburbs."

The last decent rainfall in Sydney was recorded on August 4, when 13.8 millimetres fell on the city. Just 1.2 millimetres fell on August 28 and 0.2 millimetres fell on September 14.

The dry spell has forced Sydney residents to increase their water consumption by 25 per cent, compared with the same period last year, in an effort to save their parched plants.

The rain also created a spectacular sunrise for those up early enough to enjoy it.

Tuesday will be dry but there is more rain on the way with Sydney expected to receive light rainfall throughout the rest of the week.
