Weather or Not
Which brings us to the weather. Since you're no fool, you know not to paint in the rain. Rain is wet. Wet makes paint run, and doing outside chores in the rain makes one feel Eeyore-like, to boot. You've got this one down. You will paint at the height of summer, in 90-degree F (32-degree C) weather, with a stiff breeze that'll make everything dry extra fast! You're a genius. Even better, you're going to be a tan genius.
Wrong. Painting in the hot sun is actually almost as bad of an idea as painting in the rain. Scorching hot or just windy? Either condition could mean the paint dries too fast, leading it not to set properly -- which means peeling, flaky exteriors [source: California Paints]. Too humid, and the paint will not dry well at all; it might even develop the same kind of sweaty exterior that you have, painting in the too-hot heat.
