Sydney has woken up to a thick blanket of smoke over the city as NSW heads into the first of two "tough days" this week with temperatures likely to rise to the 40s and little-to-no rainfall forecast.
Most of NSW's east coast is under severe or very high fire danger ratings, with more than 50 fires burning across the state of which 28 remain uncontained.
All are at "advice" level and more than 1300 firefighters are on the ground.
