NSW Heatwave Update: Warnings Lifted Across Most Regions, South Coast Still at Risk

NSW Heatwave Update Issued at 2:50 pm EDT on Sunday, 11 January 2026

A significant shift in weather conditions is underway across New South Wales, with severe heatwave conditions easing over most parts of the state. According to the latest warning, the Severe Heatwave Warning now applies only to the South Coast, while heatwave warnings have been cancelled for a large number of inland, coastal, and metropolitan districts.

Although the worst of the extreme heat has passed, authorities caution that low-intensity heatwave conditions may persist in some areas into mid-week, particularly along parts of the South Coast.

Areas of NSW Currently Under Severe Heatwave Warning

The South Coast of New South Wales remains under a Severe Heatwave Warning, with communities such as Batemans Bay and Bega most likely to be impacted. While temperatures are no longer at peak extremes, the lingering heat combined with warm overnight conditions continues to pose health risks, especially for vulnerable groups.

Heatwave Warnings Cancelled Across Much of the New South Wales

Heatwave warnings have now been cancelled for the following regions:

• Snowy Mountains

• Hunter

• Riverina

• Southern Tablelands

• Central West Slopes and Plains

• Central Tablelands

• Mid North Coast

• Illawarra

• South West Slopes

• Metropolitan areas

The cancellation reflects a noticeable reduction in heat stress, as cooler air moves across the state and daytime temperatures trend closer to seasonal averages.

Temperature Overview according to NSW Heatwave Update

Current forecasts indicate:

• Maximum daytime temperatures are expected to range from the mid to high 20s Celsius in eastern parts of New South Wales, including coastal districts.

• Western areas of the state will experience warmer conditions, with temperatures increasing into the low to mid 30s Celsius.

• Overnight minimum temperatures are forecast to fall between the low teens and high teens, offering improved overnight relief compared to recent days.

This drop in nighttime temperatures is particularly important, as sustained warm nights are a key contributor to heat-related illness during prolonged heatwave events.

Outlook for the Coming Days According to NSW Heatwave Update

Meteorologists advise that heatwave intensity will continue to ease over the next few days, with low-intensity heatwave conditions lingering in isolated areas into mid-week. While these conditions are generally less severe, they can still affect people who are sensitive to heat, particularly if adequate cooling and hydration are not maintained.

Residents in the South Coast region are encouraged to remain alert and continue monitoring official weather updates, especially if temperatures rise again or humidity increases.

Health and Safety Advice for NSW Heatwave

Even as conditions improve, heatwaves remain dangerous, particularly for:

• Older adults

• Babies and young children

• Pregnant and breastfeeding women

• People with chronic medical conditions

• Anyone feeling unwell or dehydrated

To reduce heat-related risks, emergency services recommend the following precautions:

• Spend time in cool environments such as air-conditioned homes, libraries, community centres, or shopping centres.

• Close windows and draw blinds, curtains, or awnings early in the day to prevent heat from entering your home.

• Use fans or air-conditioners, if available, to maintain safe indoor temperatures.

• Stay well hydrated and check regularly on family members, neighbours, and friends who may be more vulnerable to heat.

Stay Informed for any further Heatwave Warning

While the worst of this heatwave event has passed for most of New South Wales, weather conditions can change quickly. Residents are advised to stay informed through official weather warnings and forecasts and continue taking sensible precautions during warm conditions.

Further updates will be issued if conditions change or if heatwave warnings are adjusted in the coming days.
