NSW swelters as spring heatwave warnings issued


Parts of NSW are sweltering as spring temperatures soar into the 30s amid heatwave warnings for the south coast.

The Bureau of Meteorology alert covers the NSW coastline from south of Sydney to the Victorian border, with locations like Batemans Bay expected to face the worst conditions on Sunday.

The rest of the state is also experiencing the unseasonable spring heat with parts of the Hunter including the wedding hotspot of Tocal reaching 34C just after 1pm.

The summer-like conditions extend up to central parts of NSW, with Walgett reaching 34.8C just before 2pm.

It was slightly cooler on the coast as Bondi in Sydney's east hit 32C, while Penrith in the city's west got up to 33.6C.

NSW Police urged patience on Sunday with thousands of people flocking to the city for the Sydney Marathon.

The hot weather is expected to last until Wednesday when a cool front is predicted to push across the state, dropping temperatures back to average.

Heatwave warnings apply when overnight temperatures stay elevated over a period of consecutive days, leading to health problems when people are unable to properly cool down.

The bureau warned on Sunday maximum temperatures over the coming days will continue to reach the low to mid-30s with overnight minimum temperatures in the mid-to-high teens.

It said these temperatures are above average by around 10-15C, and are persisting for an unusually prolonged period for this time of year.

The health department is urging people to take the weather seriously, with the risk of heat stroke often underestimated by people until they fall ill.

Older people, babies, children, pregnant and breastfeeding women, people with medical conditions and those who are unwell are urged to take care and stay out of the heat.

Winds have remained calm with no major fire warnings in effect in the state although rural firefighters are urging people to be prepared given the conditions.
