That being said, of course not. Can both statements be true at the same time? Sort of...
If you are contemplating getting the whole house repainted before the rainy season, it is most likely TOO LATE. If you need to squeeze in a touch-up area or two, go for it.
A lot has to do with the unpredictable nature of Mother Nature. Today for example, is currently misty with a rainy afternoon approaching. But tomorrow and Wednesday should be clear, so that means some good last minute exterior painting weather.
Ideally it should be at least 55 degrees and dry. What happens when its not as dry? It takes the paint film a lot longer to cure (softer paint film, more difficult to add that 2nd coat). And we don't want you painting in the direct rain - it could wash off.
By mid-October you should be finishing up your projects outside - just in time to head indoors and repaint the dining room for the holidays!
