When it reaches about 30 C in my back garden (that’s 86 F) you can tell it’s getting hot without looking at the thermometer. The most obvious change is the bees start hanging out in a beard formation. The house bees work really hard to keep the brood at a constant temp (about 35) and if it gets too cold, all hands are called on deck to jog in place (or the bee equivalent which is shuddering) to make heat. If it gets too hot they flap like crazy to create a draft and the excess field bees are kicked out of the hive (shouldn’t they be collecting pollen and nectar anyway?).
The chickens are trapped in their down suits 24 x 7. When it gets hot their best defence is to sit in the shade waiting for the heat wave to pass. Failing that, they open their beaks and lift their wings. I’m not sure how much that helps but their combs and wattles are horribly inadequate radiators.
The veggies wilt – or those with big soft leaves do – as the temp rises. I have started stringing a temp shade cloth over my latest seedlings to protect them from the blasting sun, but they need to either cope with the heat or turn up their toes – there’s only so much a gardener can do to make veggies happy.
I don’t like it when it nears 30 either. My strategy is a little different, I hide inside with a bowl of ice cream. I don’t have an air conditioner but ice cream (or my sorbet) is a workable alternative 🙂
