I agree that small fruit and cherries have a better chance of doing well no matter what the weather. Or at least, there are some among them that will do fine in the cold, others that keep on going in the heat. The way the weather has been swinging back and forth, we don't know what to expect. So... plant more varieties, some will make it!
We are still in the 'heat wave' here too. Temperatures consistently 4-8 C above average, humidex higher. When it goes back to normal, I'll be finding it cold.
