Overview: A weekend heatwave is on the way
A heatwave is forecast to blanket parts of New Zealand’s east coast this weekend, with hot air sweeping in from Australia. MetService indicates many areas will experience unusually warm conditions on Thursday, and temperatures could soar beyond 30°C for the weekend. Hastings is specifically flagged to reach as high as 37°C, a number that underscores the need for careful preparation and smart daily choices.
What is driving this heatwave?
The weekend’s high temperatures are driven by a large high-pressure system interacting with hot air from Australia. As this air mass moves over the North Island and into the upper South Island, it traps heat and reduces overnight cooling, leading to a prolonged period of warm to hot conditions. While heatwaves are common in summer, the intensity and persistence of this event warrant proactive safety measures for residents and visitors alike.
What to expect by location
Forecast models suggest a broad regional pattern: Thursday will bring a warm spell for many communities, followed by a weekend that will likely exceed typical February or March averages. Hastings, in particular, could see temperatures peaking around 37°C, with other eastern districts flirting with the 30°C-plus range. Overnight temperatures are expected to stay relatively high compared with average for this time of year, contributing to sustained heat stress.
A practical forecast snapshot
- Thursday: Warm day with rising humidity in many districts.
- Friday to Sunday: Heatwave conditions persist; daytime highs predominantly above 30°C.
- Overnight: Mild to warm nights; limited relief from daytime heat.
<h2Health and safety: protecting yourself and others
Extreme heat can pose real health risks, especially for the young, the elderly, people with existing medical conditions, pregnant individuals, outdoor workers, and pets. Hydration, shade, and air-conditioned environments are key to staying safe. If you have to be outside, plan activities for cooler parts of the day and take frequent breaks in the shade.
Top tips to stay cool and safe
- Drink water regularly, even if you don’t feel thirsty. Avoid alcohol and limit caffeine.
- Wear lightweight, light-colored clothing and a wide-brimmed hat when outdoors.
- Use fans or air conditioning if available. For places without cooling, visit public cool spaces such as libraries or shopping centers.
- Limit strenuous outdoor activities to early morning or late evening.
- Never leave people or pets in cars, even with windows cracked.
- Check on neighbors, especially older adults and those with health conditions.
<h2Practical steps for households and communities
Homes can be prepared to minimize heat buildup. Close blinds or curtains during peak sun hours, vent hot air during cooler periods, and consider temporary cooling solutions like fans or portable air conditioning. Employers and schools can stagger outdoor work or activities to cooler times and ensure access to hydration stations and shaded rest areas.
<h2What to monitor and where to seek updates
Stay informed through official channels. MetService updates, local council advisories, and health department notices will provide the latest heat indices, warnings, and practical guidance. If conditions worsen, communities may see additional alerts or heat-health recommendations issued in real time.
In case of emergencies
For heat-related emergencies, contact emergency services immediately. If you or someone nearby experiences symptoms such as severe confusion, dizziness, fainting, or heat stroke, seek urgent medical attention and move to a cooler place while waiting for help.
Bottom line
With Hastings potentially hitting 37°C and surrounding areas staying hot through the weekend, preparation is essential. Plan ahead, hydrate, protect vulnerable people, and stay tuned to reliable forecasts for updates as the heatwave unfolds.
