Storm season and your Northern Beaches move: a wet-weather plan

When is storm season in Sydney?

October to March. Every official source we checked puts those six months inside storm season. A Northern Beaches move booked anywhere in that stretch needs a wet-weather plan as standard, not as an extra.

No single agency publishes that window. It is where four official statements overlap:

• NSW SES says NSW Storm Season falls between September and April.
• The Bureau of Meteorology says “October to April is the peak time for severe weather in Australia”.
• The Bureau's thunderstorm guide says severe thunderstorms mostly occur between September and March.
• The NSW Government says storms are more likely between October and March.

Lay them side by side and the months all four share are October, November, December, January, February and March. September and April appear in some ranges and not in others.

The overlap is where the odds stack up, but storms are not fenced in by the dates. NSW SES, the Bureau's thunderstorm guide and the NSW Government all say they can happen at any time of year.

NSW summer school holidays for the Eastern division fall inside that window, running Friday 18 December 2026 to Wednesday 27 January 2027.

The Bureau's severe weather season statement came out on 8 October 2026. The season is under way now.

What makes a thunderstorm severe, and how long it lasts

The Bureau calls a thunderstorm severe when it brings any one of these: hail 2 cm or more, wind gusts 90 km/h or more, tornadoes, or heavy rain that may cause flash flooding. It calls one very dangerous at hail 5 cm or more, gusts 125 km/h or more, or intense rainfall.

Those are the words to listen for in a warning. A loaded ramp, an open truck and a stack of cartons on the footpath are exposed long before a storm reaches those numbers.

Timing matters as much as strength. A typical thunderstorm lasts about 30 minutes to an hour, so one can mean a pause rather than a lost day. Severe thunderstorms can last many hours.

Storms are broadly forecastable, but exactly where and when they form is much harder to forecast. That is why the Bureau tells you to check its warnings and the radar whenever storms are forecast.

Which alerts to set before moving week

Storm warnings in NSW follow the Australian Warning System: Advice (Yellow), Watch and Act (Orange) and Emergency Warning (Red). The Bureau issues the severe weather and severe thunderstorm warnings.

Two apps can do the watching for you:

• The Bureau recommends the BOM Weather app with notifications set for your location.
• NSW SES recommends Hazards Near Me with watch zones set for floods and severe weather.

In moving week, set a watch zone on both addresses: the house you're leaving and the house you're going to.

Don't hold off until an official warning arrives, because NSW SES says you may not always receive one, so treat heavy clouds, darkening skies, increasing winds, thunder and lightning as your signal.

What to do if a storm is forecast on moving day

1. When you book: agree with your removalist what happens if a severe thunderstorm warning is issued; check your insurance General guidance
2. Moving week: set BOM Weather notifications and Hazards Near Me watch zones Bureau of Meteorology, NSW SES
3. Day before and morning of: check BoM forecast, warnings and radar Bureau of Meteorology
4. Warning issued, storm not here yet: secure or remove items that could blow around; unplug devices and modems; park undercover or away from trees, powerlines and drains NSW Government
5. Flash flooding forecast: leave early, only if safe; check Live Traffic NSW NSW Government
6. Severe storm overhead: stay indoors in the smallest room with the least windows; never enter floodwater NSW Government
7. After: check structural stability before entering; be cautious of asbestos NSW SES

Decide the plan B before the forecast forces it. When you book, ask your removalist what happens if a severe thunderstorm warning is issued for your date. Will the job pause, move to another day, or go ahead in stages?

That conversation is easier weeks out than at 7am with the radar lighting up. If you are getting a quote from Palm Beach Removals, ask us the same question.

Check the Bureau's forecast and warnings the day before the move and again that morning. If storms are on the cards, keep the radar open.

If a warning is issued before the storm arrives, NSW advises you to:

• secure or remove items that could blow around
• unplug electrical devices and modems
• park the car undercover or away from trees, powerlines and drains

On a moving day, that means three things. Pack the modem early. Keep cartons inside rather than staged on the porch. Leave room at the kerb for vehicles to stand clear of trees and drains. Our guide to where the truck actually stops covers the kerb side of that.

If flash flooding is forecast, NSW says to leave early, but only if it is safe. Leaving at the last minute can be dangerous because roads may be blocked. Check Live Traffic NSW for your route.

If a severe storm arrives mid-move, stop. NSW says to stay indoors in the smallest room with the least windows.

NSW SES warns it may not be able to rescue you during storms. Nobody should be out on a ramp or a driveway finishing the last load.

Storm-proofing the old house and the new one

THE STORM'S PATH FROM ROOF TO KERB

Trees and roofs come first for a reason. NSW SES responded to more than 23,416 incidents last storm season. Of those, roughly 7,000 involved fallen trees and more than 6,500 involved leaking or damaged roofs.

Added together that is roughly 13,500 incidents, a little over half of the 23,416. That is our estimate from the page's rounded figures.

The NSW Government's home checklist says to:

• trim overhanging branches
• secure loose yard and balcony items such as furniture and toys
• clear gutters and downpipes
• know where to turn off mains power, water and gas
• check your insurance is current

The same page has a section for tenants: raise maintenance concerns with the property manager or owner, and keep copies of what you send.

Do the checklist at both ends of the move:

• The house you're leaving. Moving week is when balcony chairs and pot plants get shifted anyway. Strap them down or bring them in rather than leaving them loose by the door.
• The house you're moving to. Ask the agent or owner whether the gutters and drains have been cleared before you arrive. Find the mains power, water and gas shut-offs on your first walk-through.

A late-December move has one extra wrinkle. Council's bulky goods collection is not available in the last week of December, so unwanted outdoor furniture may have to sit in the yard into the new year. Tie it down while it waits. Our Council clean up guide covers what can go out and when.

Cars need a plan too. NSW SES says to shelter vehicles undercover if possible, otherwise park away from trees, and cover the car with a tarpaulin or blankets if hail is predicted. It also says to keep a full tank of fuel in case you need to evacuate, and to keep your phone charged. Both are easy to do before any moving day.

If either address is on the beach or a cliff edge, take note: the NSW Government says coastal erosion can occur quickly in a storm, and it points to NSW SES for beachfront and cliff areas. Read that guidance before moving week.

If a storm damages the new place before you move in, slow down. NSW SES says to check structural stability before entering. It also says to be cautious of potential contaminants including asbestos.

Driving and carrying in the wet

If you must drive in a storm, NSW advises you to slow down, turn on headlights, leave a larger gap to the car in front, and wait until visibility improves if conditions worsen.

In a severe storm, put hazard lights on and pull over safely away from traffic. Never enter or travel through floodwater.

On foot, the danger is underfoot. Don't carry cartons up or down wet steps while a storm is overhead. Wait for it to pass.

Steep blocks make this matter more. Our guide to grading hillside access explains how a carry is assessed.

NSW SES says to follow the SafeWork NSW pocket guide to ladder safety whenever you use a ladder. Moving week is a poor week to be up a ladder in a hurry. Clean the gutters well before the date, or leave that job to someone equipped for it.

Check your insurance before the boxes move

Storm cover and flood cover are not the same thing: most home and contents insurance includes storm cover, but for some policies flood cover is optional.

Read your own policy for what it covers and what it excludes, and confirm it is current at both addresses. How your goods are covered while they are on the truck is a separate question. Put it to your insurer and your removalist, and keep the answers in writing.

If you rent, the same habit protects you. Photograph any storm damage at the place you're leaving or arriving at. Keep copies of every message to the landlord or agent about it.

Planning a summer move with Palm Beach Removals

If your moving date falls between now and autumn, treat the weather as part of the booking, not a surprise on the day. Set your alerts, tidy both houses, and agree the plan B early.

Request a quote from Palm Beach Removals with your date and both addresses, and ask what happens if a severe thunderstorm warning lands on the day. If the carry is steep or tight, our page on difficult access removals is a good place to start.
