In summary
- New South Wales’ storm season runs from September to April, and a strong El Niño is expected to make summer 2026/27 warmer and drier than usual, with elevated bushfire risk flagged for parts of northern and south-eastern NSW.
- In a strata scheme, a short pre-summer check of gutters, drainage, cooling, fire safety measures and insurance can preempt most of the common summer headaches before they start.
- The Hazards Near Me NSW app, NSW SES, NSW RFS, Adapt NSW and the Bureau of Meteorology all offer free, practical ways for committees and residents to stay informed.
Summer arrives early in Sydney and regional NSW
Technically, summer starts in December. In practice, the NSW SES counts storm season from September to April, so the first humid afternoons and rolling thunderclouds are already on the way. Sydney summers are a large part of why people live here. They also bring heat, sudden downpours and the odd burst of hail, and in an apartment building those things are shared. When a downpipe blocks or the lift struggles in a heatwave, it is everybody’s problem.
Think of this as a community notice rather than a cause for concern. Early in the season is when a strata committee has the most room to move, and the jobs are smaller and potentially cheaper than they will be later.
What the outlook is saying
According to the Bureau of Meteorology, a strong El Niño has developed in the Pacific and is forecast to peak in late spring or summer, potentially the strongest since records began. That usually tilts eastern Australia towards a warmer, drier summer. After a dry, warm start to 2026 in the north-east of the state, the national bushfire outlook released in August identified increased fire risk in northern and south-eastern New South Wales, and fire agencies have encouraged communities to prepare early.
That said, a drier summer does not mean there won’t be storms. The SES notes that February is typically its busiest month, mostly for storm damage, and coastal weather systems that can deliver intense rain. So whilst heat and fire risk are the headline, summer storms still need addressing.
Sydney, its fringes and NSW regional areas
Across the metropolitan areas, heat is the first thing residents notice. Western Sydney routinely runs several degrees hotter than the coast, and a run of very hot days can send electricity demand climbing as air conditioning switches on across the city and outer suburbs, with building plant and lifts under load at the same time. Late-afternoon thunderstorms bring the other half of the picture: hail on skylights and roof tiles, flash flooding in low-lying streets and water backing up wherever a gutter or stormwater pit is blocked. Along the bushland fringes, from the Blue Mountains to Hornsby, Sutherland and the Northern Beaches, bushfire preparation is part of every summer.
In regional New South Wales the balance changes with geography. Inland, heat and grassfires can dominate, and this year’s outlook has drawn particular attention to the north and south-east of the state. On the coast, east coast lows can bring days of heavy rain and damaging wind, as the Northern Rivers’ residents know well. Wherever a strata scheme is located, these recommended checks are worth implementing.
What summer can look like in a strata scheme
A few examples of how the season can show up in a building, and what a committee can do ahead of time:
- Roof, gutters and drainage. Leaf litter in gutters and on flat roofs is the classic summer problem: fuel for embers on a bushland fringe, and a blockage that overflows into ceilings when a storm hits. A gutter clean, a check of stormwater pits and a test of the sump pump are top of the list.
- Plant, lifts and power. Shared air conditioning, lift motors and car park exhaust fans that need a service should be booked in before the first heatwave rather than during one. Emergency lighting and exit signs are among the fire safety measures the owners corporation certifies each year in its annual fire safety statement, so a pre-summer double check supports that obligation too.
- Balconies and trees. Storm gusts can turn outdoor furniture and planters into hazards for anyone below. A reminder to residents, with balcony items, to keep the risk down. Trees close to the building may need an arborist’s attention is leaning on or overhanging the building.
- Insurance and contacts. Check that the building’s strata insurance is up to date and that the committee understands how storm damage is covered and claimed. Make sure residents know the after-hours numbers for the strata manager and emergency trades, and know to call the SES for storm and flood assistance.
Bigger-ticket items, such as a roof membrane or a cooling plant approaching the end of its life, are what the capital works fund and its 10-year plan are for, so the funding is in place when the work is needed.
Help is close at hand
There is no shortage of great, free support for staying informed. A few worth sharing with residents:
- Hazards Near Me NSW: The official app from the NSW RFS and NSW SES. Download the app and set a watch zone for your suburb to receive warnings for bushfire, flood and severe weather, plus Fire Danger Ratings and Total Fire Ban days.
- NSW SES: Storm and flood preparation guides, and emergency assistance on 132 500.
- NSW Rural Fire Service: Bushfire preparation advice and a bushfire survival plan template for schemes near bushland.
- AdaptNSW: The NSW Government’s climate adaptation site, with plain-language information on how conditions are changing in each region of the state.
- Bureau of Meteorology: Official heatwave and thunderstorm warnings, and the BOM Weather app for forecasts and radar on your phone.
- For anyone who wants the bigger picture there’s Climate Council, with independent and readable summaries of longer-term climate trends.
Ahead of the season, not behind it
Sydney and regional NSW does summer better than almost anywhere, and most seasons pass with far more beach days and picnics than call-outs. The case for an early check is simply that small jobs done in spring are easier and cheaper than urgent ones in February, and a building that is ready lets everyone relax and enjoy the weather. If this summer is as warm as the outlook suggests, that readiness will be worth having.
How ASM Strata Management helps
Australian Strata Management can help your strata committee decide what needs attention before summer, line up the right trades and keep owners and residents informed as the season unfolds. Our local teams know your building, your council area and the NSW requirements that apply.
FAQs
When does storm season start in NSW?
The NSW SES defines storm season as September to April, so it is already underway by the time the weather warms up. February is typically the busiest month for storm-related call-outs.
Will El Niño mean fewer storms in Sydney?
El Niño generally points to a warmer, drier summer, but Sydney’s afternoon thunderstorms and coastal rain events still occur. The Bureau of Meteorology treats El Niño as one influence among several, so it is sensible to prepare for both heat and storms.
Who is responsible for clearing gutters and preparing common property?
The owners corporation must maintain and repair common property, and the strata committee typically arranges this through the strata managing agent. Owners and residents look after their own lots, including balconies.
What should we check for fire safety before summer?
Confirm the fire safety measures listed in your annual fire safety statement, including exit lighting, extinguishers and alarms, are serviced and working. Schemes near bushland should also clear leaf litter, check ember guards and know their local Fire Danger Rating.
