December 2020 marked the end of what was an unusual year, to say the least. Did you know that it was also Perth’s second warmest December on record? The hottest December currently on record for Perth is December 2019.

Here are some hot facts about the temperature in December 2020:

  • Both mean maximum and minimum temperatures were well above average.
  • There was a hot spell leading up to Christmas with three days in a row where temperatures reached over 40°C.
  • Christmas Day reached 40.4 in the Perth metro area … which you would be well aware of if you decided to serve your Christmas pavlova outside.

January 2021 was also hotter than usual, with both mean maximum and minimum temperatures above average. On Perth Metro’s warmest day of the month, 8 January 2021, the maximum temperature reached a sweltering 42.2 °C.

On top of all of this, February started off with a snap lockdown as part of WA’s COVID-19 response. This meant more of us in WA were at home using air-conditioning, appliances and more devices during the hot weather.

We might be used to hot spells during our WA summers but sometimes, this can lead to using more power than usual. Here’s what you can do to keep your cool and try to avoid a higher electricity bill than expected.

By planning ahead when hot weather is forecast, you could be able to reduce your energy use. For example, if you know it’s going to be a hot day, you might keep your blinds down all day to keep the harsh sun out. This could help your home feel a lot cooler without the need to crank your air-conditioning.

If you do use your air con, try not to leave it going all day. This applies to your pool pump too, if you have a pool. Without realising, you might use more electricity than you usually would, which could lead to a higher bill than you were expecting.

Practise your sun salutations

If you’ve decided mindfulness is going to be a focus for you this year, consider expanding your awareness to your solar panels if you have them. By shifting a few habits – such as starting or setting a timer to start a load of washing at lunch instead of in the evening – you could make the most of the electricity generated by your solar panels. This could help to reduce the amount of electricity you draw from the grid.
