If you're eager to refresh your home's curb appeal, timing matters just as much as color. And when it comes to outdoor painting, temperature isn't just a detail—it's a dealbreaker. At Pro Works Painting, we've painted through all four Canadian seasons (sometimes in a single week!), so we know exactly how the weather affects your results.
Here's everything homeowners, strata managers, and contractors need to know about the ideal temperature for exterior painting—and what to watch out for if you're painting in less-than-ideal conditions.
Paint doesn't just need to dry—it needs to cure. And that process depends heavily on temperature. Too cold? The paint won’t form a solid film. Too hot? It may dry too quickly, causing adhesion issues, cracks, or peeling later on.
Latex and acrylic paints especially rely on evaporation, which is influenced by air and surface temperature, as well as humidity. Cold temps slow evaporation. Hot temps speed it up, sometimes too fast for paint to settle evenly.

Most professional-grade exterior paints work best between 50°F and 85°F (10°C to 30°C). Ideally, aim for 60–70°F (15–21°C) with mild humidity and no forecasted rain.
Nighttime lows are just as important: if it drops below freezing within 24–48 hours, your fresh coat may not cure properly.
Check both the air and surface temperature before you start. A sunny wall might be hotter than the air. If you can’t touch the surface comfortably with your hand, it’s too hot to paint.

Yes—but carefully. Some newer exterior paints (like BEHR Marquee or Sherwin-Williams Resilience) are rated to 35°F (1.6°C). However, drying time will be longer, and conditions must remain stable for a few days.

Yes. Paint can flash-dry in direct sun above 90°F (32°C), especially on metal or dark surfaces. That creates visible lap marks, blistering, or even peeling within weeks.

What is the lowest temperature you can paint outside?
35°F (1.6°C) is the minimum for many newer formulas, but 50°F (10°C) is safer for most paints.
Can you paint exterior walls in high humidity?
High humidity slows drying and increases the risk of mildew. Stay below 85% humidity for best results.
How long does paint need to dry before cold weather hits?
At least 24–48 hours of above-freezing temps are ideal for a full cure.
Should I paint in spring or fall?
Both are great! Just avoid extreme swings in daytime/nighttime temperatures.
