If you have pets, particularly elderly ones, please take special care of them this weekend. Do whatever you can to keep them as cool as possible, mist their enclosures, check and change their water frequently (chooks will avoid drinking warm water, and can die in a matter of hours in heat like this), put frozen blocks of ice in their water, even bring them into the aircon if you can.
Likewise, if you have any old sheets or net curtains, use them to cover any plants that are prone to burning. It might look daggy but it’ll make all the difference.
