El Niño Hub


Welcome to the El Niño Information Hub

This Information Hub provides the latest advice and guidance to help you prepare for the possible impacts of El Niño.

It brings together information from our partner agencies like Fire and Emergency New Zealand, Health New Zealand and the Ministry for Primary Industries.

Hawke's Bay Emergency Management has a coordinating role, with many aspects of the response to El Niño being led by our partner agencies.



What is El Niño, and what does it mean for Hawke’s Bay?

Summer is forecast to be hotter, windier and drier than normal, with the potential for severe weather too.

Summer is forecast to be hotter, windier and drier than normal, with the potential for severe weather too.

El Niño is a natural climate pattern that can influence weather patterns around the world, and this year’s El Niño is forecast to be one of the strongest on record.

Early forecasts from Earth Sciences New Zealand suggest Hawke’s Bay will likely experience one of the hottest, windiest and driest summers in recent years, with possible severe weather too.

Combined, this increases the likelihood of drought, fires and heat-related problems, with possible severe weather too.

Fire

Fire

El Niño conditions can bring stronger westerly winds, combined with hotter and drier weather increasing the risk of fires across Hawke's Bay

Heat

Heat

El Niño conditions can bring hotter-than-average temperatures to Hawke’s Bay, increasing the risk of heat-related illness.

Drought

Drought

El Niño conditions can bring lower rainfall and higher temperatures to Hawke’s Bay, increasing the risk of drought.

Severe Weather

Severe Weather

El Niño can bring stronger and more frequent westerly winds, along with rapidly changing weather. Heavy rain and storms can still occur.

El Niño conditions can increase fire risk across Hawke’s Bay. Strong westerly winds, combined with hot, dry weather, can make fires more likely to start and spread quickly. Fires can be especially difficult to control in windy conditions. 

If you see smoke or fire and believe there is a risk to people or property, call 111 and ask for 'Fire’.

What this may mean for you:

  • Smoke can affect air quality and health, particularly for babies, older people, disabled people, and people with serious long-term health conditions.
  • Fires can lead to road closures, evacuations, electricity outages and interruptions to phone or internet services. This can make it harder to get home, access services or stay in contact with family and friends.
  • Fire season restrictions may begin earlier and remain in place for longer periods. This can affect outdoor burning, machinery use, land management, recreation and planned events.
  • Farmers, growers and rural businesses may need to change work plans, delay burn-offs or harvesting, protect stock, and ensure machinery and water supplies are ready.

El Niño conditions can bring hotter-than-average temperatures to Hawke’s Bay, increasing the risk of heat-related problems when temperatures rise including heat rash, heat cramps, sunburn, heat exhaustion, and heatstroke. 

For health advice, call Healthline on 0800 611 116. In an emergency, call 111 and ask for Ambulance.

What this may mean for you:

  • Some people may need extra support during very hot weather, particularly babies, young children, older people, people with existing health conditions or on certain medications, people living alone, and those without a cool place to go.
  • Hotter weather can make homes, workplaces and vehicles uncomfortable or unsafe, particularly where there is limited shade, ventilation or access to cooling.
  • Outdoor workers, including people in construction, farming, horticulture and emergency services, may be at greater risk of dehydration, heat stress and fatigue. Businesses may need to adjust work hours, provide shade and water, and build in more rest breaks.
  • Heat can affect animals and livestock too. Farmers and pet owners may need to make sure animals have shade, water and appropriate care during hot weather.

El Niño conditions can bring reduced rainfall and higher temperatures to Hawke’s Bay, increasing increasing the risk of drought. Drought can build slowly over months.

What this may mean for you:

  • People on town water supplies may face water restrictions as councils work to conserve available water. Restrictions can limit activities such as watering gardens, washing cars, filling pools or using outdoor sprinklers. Follow advice from your local council.
  • Rural properties, lifestyle blocks and homes relying on rainwater tanks may need to carefully monitor supply and arrange alternative water earlier than usual.
  • Farmers and growers may face reduced feed and irrigation water, additional costs, and difficult decisions about livestock, crops and planting. Dry conditions can also increase stress on animals and reduce production.
  • Drought can place pressure on businesses that rely on water, including farms, horticulture, hospitality, construction and recreation providers. Businesses may need to adjust operations, reduce water use or plan for higher costs.
  • Long dry periods can also affect wellbeing. Financial pressure, uncertainty and the extra work involved in managing water and animals can be stressful make sure to check in on neighbours, friends and whānau who may need support.

El Niño conditions are often associated with stronger and more frequent westerly winds across New Zealand. Severe weather, including heavy rain and the chance of ex-tropical cyclones, is still possible during an El Niño season. Hawke’s Bay may experience a range of weather conditions, not just hotter, drier or windier weather.

If severe weather creates an immediate risk to life or property, call 111.

What this may mean for you:

  • Strong winds can damage roofs, fences, signs and other structures. They can also bring down trees and branches, damage vehicles and powerlines, and block driveways, roads and access routes.
  • Outdoor items, such as furniture, trampolines and building materials, can become airborne and cause injury or damage.
  • Heavy rain can cause surface flooding, slips, overflowing drains and streams, and localised flooding in low-lying areas. Roads may be closed so plan ahead and avoid travelling through floodwater.
  • When strong winds and heavy rain occur together, impacts can be more severe. Electricity, phone and internet outages may affect homes, farm operations and business services.
  • Businesses may need to secure outdoor equipment, check emergency plans, make arrangements for staff, and prepare for disruptions to electricity, stock deliveries or customer access.

What does this mean for me?

In Hawke’s Bay, we are used to adapting to changing weather. We have practical know-how, and we look after and support one another when things get tough.

For some of us, El Niño may just mean a hotter, windier, drier summer. For others, it may bring added pressure, especially where water, health, work, animals, homes or businesses are affected.

No matter what El Niño brings this summer, there are things we can do that make all the difference and may just make your life a bit easier and lessen some of the challenges you may face.

What can I do now?

Doing a few things now can give you more choices later and make it easier to support the people around you.

1. Think about the ways that this weather, like heat, drought, wildfire, and strong winds, could affect may affect you at home, at work or on the weekend

2. Make a plan and talk with those around you and your loved ones  about what you would do, where you would go, and what you would take if you needed to leave home quickly

3. Check or put together your emergency supplies and a grab bag, in case you need to leave quickly - remember you can use what you already have around the house, rather than buying everything new.

Check out the lists below and start with one thing this week that will make the biggest difference for you.

Living in town often means you are close to neighbours, shops, and support. That can make it easier to check in on each other and access help. Hotter, drier and windier weather can bring water restrictions, heat stress, fire risk and electricity outages.

  • Keep a few days’ drinking water at home, and top up supplies if needed
  • Prepare a grab bag with important items in case you need to leave in a hurry
  • Think about how you will keep your home cool on very hot days.
  • Secure outdoor furniture, trampolines, rubbish bins and other loose items before strong winds.
  • Keep up to date with weather forecasts, weather warnings and know where to go for emergency information if the electricity or internet is out.

People with lifestyle properties are often used to planning ahead, looking after their property and helping neighbours. Hotter, drier and windier conditions may put extra pressure on tank water, heat stress, feed and water shortages and fire risk.

  • Check tank levels now and save the contact details of a local water supplier.
  • Clear dry vegetation, firewood, woodpiles and other flammable material away from homes, sheds and other buildings.
  • Make sure animals have enough drinking water and shade - Plan for supplementary feed now  and water requirements (animals will drink more water than usual)
  • Secure loose items and check trees that could fall on buildings, fences or access routes.
  • Make a plan for what you will do if electricity is out
  • Have a grab bag if you need to leave quickly.
  • Keep up to date with weather forecasts, weather warnings and know where to go for emergency information if the electricity or internet is out.

Farmers and growers are used to reading the seasons, adapting to changing conditions and making practical decisions for their land, animals and businesses. During a dry period, making decisions early gives you more options and reduces stress later.

  • Set your decision points early -Know what tank level, feed supply, soil-moisture level or forecast trigger will prompt you to order water, secure feed, adjust operations or seek support.
  • Make a drought plan for household, stock and operational water needs.
  • Monitor water supplies regularly and arrange deliveries early if needed.
  • Consider supplementary feed requirements before supply becomes limited.
  • Ensure stock have reliable drinking water and shade; animals may need more water during very hot weather.
  • Check fire restrictions before using machinery or carrying out activities that could create sparks.
  • Talk early with advisers, suppliers, neighbours and support services if dry conditions persist.

Businesses know their people, customers and day-to-day operations better than anyone else. A little planning now can help things run more smoothly when heat, dry conditions, fire risk or power outages affect normal operations.

  • Build in shade, hydration, rest breaks and adjusted workloads for staff working outdoors or in hot spaces.
  • Watch for signs of heat stress and fatigue, and adjust workloads during extreme heat
  • Check that staff know what to do during severe weather, a fire or power outage.
  • Keep emergency contacts for staff, suppliers, insurers and key service providers up to date.
  • Back up important records and data, and check how you would continue operating if power, water or internet services were disrupted.
  • Clear vegetation and flammable material from around buildings, plant and storage areas.

Frequently Asked Questions (FAQ)

Click on the question below to see the answer

Hawke's Bay Emergency Management has a coordinating role, with many aspects of the response to El Niño being led by partner agencies including Fire and Emergency New Zealand, Health New Zealand, and Ministry for Primary Industries.

Each agency leads the services and decisions it is responsible for, such as fire restrictions, health advice and water supplies. Hawke’s Bay Emergency Management will continue to monitor conditions, coordinate with partners and share official information as El Niño conditions develop

No. El Niño makes hotter, drier and windier conditions more likely, but it does not guarantee them. Hawke’s Bay can still experience heavy rain, cold snaps and severe weather.

Yes. A generally dry season can still include short periods of heavy rain, flooding, thunderstorms or ex-tropical cyclones.

El Niño can influence weather over several months. Check the latest seasonal outlooks and local forecasts, as conditions can change through spring, summer and autumn.

Water restrictions depend on local water supplies, demand and weather conditions. Check updates from your local council and use water wisely.

Monitor your tank level, use water carefully and save the contact details of a local water supplier. Arrange water early if dry conditions continue, as delivery demand can increase.
