I’m currently reading a book about Sydney, and it says that Sydney is a city governed by three winds. The nor-easter, the westerly, and the southerly. And it’s so true.
- The nor-easter brings in warm, moist air from the Pacific Ocean. It brings warm, humid weather.
- The westerly brings in hot, dry air from the interior of the Australian continent. It drives the very hottest weather, but keeps the air dry.
- The southerly is the wind of the cold change and storms. It brings cold air up from the south, often moist and laden with rain and violent winds.
On a hot day, especially in summer, the westerly wind will bake the city and dry everything up, parching the grass and blowing dust into the air. And people will wait for the southerly change, known as the “southerly buster”, to bring relief and rains.
The past few weeks the westerly has brought not only hot, dry air into the city, but also the smoke from the bushfires west of the city. But today was a blessed relief, with the nor-easter blowing fresh air in from the sea. The smoke was gone this morning, and I could see actual clouds in the sky, rather than just a uniform grey-orange pall blanketing everything. There’s still some smoke high up in the upper atmosphere, so the sky wasn’t really blue, it was more brownish, but at least today we could go outside and breathe. The only issue was that it raised the humidity a lot. I did a lot of walking today, and although it wasn’t hot, the humidity was a killer.
First thing this morning I had the car booked in for an annual service. I dropped it off at the service centre at 7:30, which fortunately is within walking distance of home. But I didn’t go straight home – I headed to my barber for a haircut. I knew he opened earlyish, but it turned out I got there at 8 and he didn’t open until 8:30. So instead of getting a haircut, I went to the supermarket and did some grocery shopping, which I carried home.
Once I’d unpacked the groceries and put them away at home, I headed out again. this time to the post office to mail a Christmas gift. I’m taking part in the reddit Secret Santa, and had a box of goodies to be sent to my secret giftee. I had good luck with the packaging – I grabbed a likely looking box from the Post Office packaging supplies and my gifts fit perfectly into the box. They were snug without being tight, and required no extra padding to stop them rattling around. This may be the first time this has ever happened!
After sending my gifts, I went back to the barber and got my haircut. I was a dollar short of the price on the wall, and said I’d go get some cash from an ATM, but the barber said he had EFTPOS now! I’ve only ever seen anyone pay cash there before, so that was a bit of a surprise. Saved me a walk to the ATM though.
Then I walked home and, not 10 minutes after I walked in the door I got a phone call from the car service place saying my car was ready to be picked up. So I walked back up there to get it. I tracked my walks on Strava and by the time I picked up my car I’d walked over 8 kilometres (5 miles). As well as servicing the car they’d washed and detailed it. When I got home I decided it was a good time to wax the car, seeing as it was now clean – and water restrictions mean it will be harder to wash again from tomorrow (more about that later).
But first I had lunch while the engine cooled down, and then after eating I waxed the car. I’d intended to start writing a new 100 Proofs that the Earth is a Globe today, but time really got away from me with all the various chores to be done. Late afternoon my wife and I took Scully out to the dog park for some exercise in the fresh air.
Now about water restrictions. Sydney has been on Level 1 restrictions for some time now, but Level 2 restrictions go into force from midnight tonight. The city’s water supply is at 45% capacity, and that triggered this change. From tomorrow, it will be illegal to use a hose for any purpose other than fighting fires – no garden watering, no washing of cars. Gardens can only be watered by drip irrigation or watering cans, and only before 10am or after 4pm. Cars can only be washed with a bucket (which makes it more difficult and laborious than using a hose – I think this measure is really designed to deter people from washing cars altogether, rather than to make everyone change from hoses to buckets, which I really don’t think saves much, if any, water as the bucket is so much less precise and you have to slop water all over the place with it to rinse the car properly).
Level 2 is mild compared to some rural towns which are on Level 4 or 5 at the moment. The details vary from town to town, but these include measures such as watering lawns and gardens allowed for a maximum of 30 minutes only by hand watering can on Sundays only before 9am or after 6pm, complete banning of washing cars by any means (you’re only allowed to wipe clean windows and mirrors), and restricting people to one shower of a maximum of 5 minutes per day or a bath with a maximum water depth of 10 centimetres. These are towns of 30 to 40,000 people with these restrictions. The drought in south-eastern Australia is terribly serious.
And the forecast for tomorrow in Sydney is not good. The westerly will be back, and with it smoke from the fires. It will bring temperatures over 40°C to the suburbs (the city is by the coast, so is usually a bit cooler, but it’ll be high 30s), as well as strong, and dry, winds. And there may be some dry lightning storms as well. All of this is a recipe for danger with regard to the ongoing bushfires. Hot dry winds will whip them up and carry embers further east, towards the city. Last Friday we had ash falling on the city as far east as my home, and some of my friends reported burnt leaves falling from the sky.
So everyone in this city of 5 million people holds their breath tonight.
