mentioned below are typical for suburbs near the coast. If you're
staying inland in Sydney's western suburbs add about 2-5deg C (4-9deg F)
to the summer highs, and reduce winter lows by about 2deg C (4deg F).
Signs that Spring has arrived in Sydney ... the flowering of beautiful magnolias, and the return of spectacular kites to Bondi Beach for The Festival of the Winds in September. (Beach photo by Marina Naidion).
season you've got to love in this city. From September through to the end
of November there's a gradual change from cool to pretty warm Sydney Australia weather.
It's time to get out and about more ... to walk through scented gardens and enjoy the spring flowers and lush new leaves on so many trees.
On fine weekends Sydney's many public parks and reserves are now busy with family picnics and barbeques.
In the middle of spring average temperatures reach about 22deg C (72deg F) in the day and drop at night to 13deg C (55deg F).
Rainfall is at its lowest in Sydney's spring.
Note: I'm adding this note on Sydney Australia weather with just a few official days of spring left. It's November 20, 2014. And it's warm ... very warm. Tomorrow (Friday) the Bondi Beach forecast is for temperatures to hit 36deg C.
That's hot for the beachside. The reason is that the cooling onshore breezes aren't expected to kick in because a heatwave's moving in from inland.
Out here in Western Sydney I'm sweating! Maximum temperature tomorrow is going to be around 40deg C. And forecasters are expecting 42deg C on Sunday (Nov 23).
To give you an idea of what spring can mean in some parts of western Sydney, here's a quick look at Penrith, nestled beneath the Blue Mountains.
Two months ago, in September (the first month of spring here) Penrith recorded one day with a max temperature of over 35deg C. In October it had 11 days with maximums over 30deg C, the highest being 37deg C. And this month (November) the max hit 40deg C on Nov 14.
Footnote: Bondi and coastal Sydney achieved 34deg C today (Friday Nov 21, 2014). In Western Sydney it reached 40-41deg C. Then a southerly change came about 6pm bringing great relief. It will stay milder tomorrow before the heat returns Sunday with possibly 39deg C for eastern Sydney and up to 43deg C out west at Penrith. That's just a little taste of Sydney Australia weather - in spring!
Crowds pack Bondi Beach on a perfect summer's day.
Summer: Sydney Australia weather really heats up for December, January and February with average temperatures ranging from about 19-26deg C (66-79deg F).
Those are averages - so expect plenty of heat. Quite likely you will experience some heatwave conditions if you're here in these months.
On 15 days a year Sydney has temperatures over 30deg C (86deg F). That might seem pretty easy to take, but there can be some amazing highs.
For instance, on January 18 2013, it reached 45.8deg C (114.4deg F) - the highest recorded maximum temperature at Observatory Hill (that's at Millers Point, close to the Harbour Bridge).
As a coastal city, sea breezes kick in during the afternoon to bring refreshing relief from summer humidity (so long as you're not too far inland!).
Hot windy days can mean there's a
great risk of bushfire. On days of severe risk national parks and
walking trails may be closed for safety. Total fire bans are common.
Listen to Sydney Australia weather reports, check out the Rural Fire Service website and
look for warning signs at the entrance to national parks.
Autumn comes to Sydney and the Blue Mountains.
Autumn: Through March, April and May the humidity drops and for me these are some of the best months of Sydney Australia weather.
The sunshine stays pretty warm, especially in March, cooling noticeably into May.
In mid-autumn average Sydney temperatures should be about 22deg C (72deg F) during the day and cooling to 15deg C (59deg F) at night.
It's likely to be the wettest in March. Most months of autumn experience from 120mm to 135mm of rain.
Rock 'n roll ride ... sometimes the Harbour Ferry meets big swells and bad weather on the way to Manly and back.
Winter: Sydney weather in June, July and August is pretty mild. I find winters are short and the often cloudless blue skies make them quite pleasant. Mid-winter average temperatures during the day are 15.5deg C (60deg F), dropping to 8deg C (46deg F) at night.
a bit chilly, isn't it? But this is mid-winter! What's it like
where you're from in the coldest months? You're probably knee deep in
Sydney Australia weather in winter can be quite wonderfully warm. Highest recorded June daytime maximum is 26.9deg C (80.4deg F). Isn't that nearly as good as it gets in the height of summer in much
of the UK?
Anyway, winter's by no means cold here! And we're actually blessed with more sunny days in winter than in summer. So, Sydney weather in winter is a walk in the park for anyone coming from, say, London.
Not much winter clothing needed
Go easy on packing the heavy winter
clothing. You really won't need more extras than a warm winter coat
and a fleecy windbreaker jacket. Bring some light summer gear so you can
enjoy the mild to warm days.
Warning: If you also plan some time up the Blue Mountains, or in Canberra or Melbourne, then that's different. Pack your woolies!
not a lot of central heating in Sydney homes or shops. This can
sometimes mean visitors from Europe feel the cold when they're indoors. So plan to meet that need.
can drop to lows of almost 2deg C (35deg F). But you're unlikely to feel
a frost unless well inland, away from the sea.
Bring some warm clothes, like jumpers, and you'll cope well with a windy day, or the wind chill of a Sydney Harbour ferry ride.
