More hazy days are expected for Sydney, according to weather experts.

“Today we saw very smokey conditions throughout the Sydney metropolitan area, and potential remains for another smokey day tomorrow,” says Peter Summers from the Bureau of Meteorology.

Experts say there’s been an unexpected influx of marijuana smoking around the city, as Sydney-siders recover from their 10-day Easter/Anzac day holiday.

“The issue is currently being compounded by a southerly wind blowing smoke down from the Central Coast where cannabis smoking rates are traditionally very high,” says Peter Summers.

Those with breathing difficulties, or those looking to avoid passive smoking, are urged to stay in doors for the next few days.

“It’s difficult to know exactly how long the smoke haze will last,” says Peter Summers. “Honestly it might just be better to spark up and ride it out like the rest of us.”
