Growing up in Illinois there were days when it was so cold you couldn't go outside, or if you did, you bundled up in extra socks and waterproof boots. You added layers under your hooded parka, a scarf around your face to protect your nose and eyes. Then came mittens--not gloves--because you needed your fingers to generate heat and keep each other warm.
In the southwest we have days when you shouldn't go outside, but they're at the opposite end of the thermometer. You don't bundle up for such weather but if you must be out for a while you do cover up: you need a brim on that hat, plus sunglasses to protect your vision, long sleeves and preferably long pants to preserve your skin, and sunscreen on the remaining exposed dermal inches.
Our temps came back into the 90s yesterday, down from over 100 degrees, and it felt like relief. It got so hot this time I could go outdoors without a sweater even at night. (Now that I love.) We'll be back to the high 80s by Wednesday--in other words, back to normal.
This camellia will survive. But it's a good argument for sunscreen.
