“It should be at least 50° F when you’re applying the paint and shouldn’t drop below 32° F at night for several days after,” says Rico de Paz, who oversees Consumer Reports’ paint tests. Even if it’s warm during the day, the paint won’t form a good film if temperatures drop too low at night.
If you’re using oil-based paints, our painting professionals recommend painting when the external temperature is ranging between 40 and 90 degrees Fahrenheit. However, if you’re planning on using latex-based paint, you should paint when the temperature is sitting between 40-70 degrees.

Frequently Asked Questions
Will paint dry outside in cold weather?
Cold Weather – As soon as the sun disappears, it can get bitterly cold – you don't us to tell you that. Most masonry paints and gloss undercoat will struggle to dry if the weather is too cold. This can be one of the most serious problems, in that there often isn't enough time for paint to fully dry in a single day.
What temperature do you need to paint outside?
Ideally, choose a day to paint your exterior with temperatures ranging from 60° to around 85°F with little to no wind. Too much wind can cause the paint to dry too quickly. 40% to 70% humidity is the perfect range to ensure that the paint dries properly.
What kind of paint should I use when it is too cold to paint?
Between 45-90 degrees If you must paint in lower temperatures, purchase the specially formulated latex paint made to perform in temperatures as low as 36 degrees F / 2.2 C. This paint contains coalescing agents that bolster paint curing attributes during low temperatures. More Considerations to Keep in Mind for Exterior Painting
