The moisture in the air makes it difficult for paint to dry completely because the water in the paint does not evaporate easily in high humidity. When the paint is applied at lower temperatures in high humidity, condensation can occur on the surface of the paint. Avoid painting when the humidity is 85% or more.
Does humidity affect painting outdoors?
Optimal relative humidity (RH) levels for exterior painting tend to be in the 40- to 50-percent range. But these humidity levels will still not prevent you from painting altogether. They simply make the job more difficult and painstaking. It is strongly discouraged to paint when there’s an RH level above 85 percent.

When the relative humidity drops below about 40% the air feels dry to skin. If very low relative humidities persist it can make the skin dry, lips chapped and can put more static in the air. In the winter when air with a low dewpoint from outside is heated and brought inside the air will decrease in relative humidity.
Does paint absorb moisture from air?
Because paint is wet and needs to dry, you would think that painting in an area of low relative humidity is best because paint will dry faster and you can finish the project in less time. But in dry climates, without a climate-specific paint, the dry air will actually absorb small particles of moisture from the paint.
What is the best time to paint outside?
So, what is the ideal weather for exterior painting? Early summer and early fall usually offer up the best weather conditions, with minimal rain and minimal fluctuations in temperature from day to night. This will ensure the paint goes on smoothly and has the chance to dry and cure properly.

Why should you not paint when it’s raining?
The paint is going to dry much slower, so expect extended drying times. This may also mean a longer recoat process. You can accelerate the drying time by opening doors and windows to increase the air flow and ventilation in the room you are painting.

As a general rule, here’s how it should be: the lower the outdoor temperature, the lower the indoor humidity. The Star Tribune breaks down how indoor humidity levels correspond to outdoor temperature: If outside temperature is 20 to 40 degrees, humidity indoors should not be more than 40 percent.
What temperature does paint dry best?
The ideal range is between 50 to 90 degrees. If it’s too hot, the paint is forced to dry quickly, which can lead to cracking or can cause a film to form on the painted surface. If it is too cold, on the other hand, the paint will struggle to bond to the surface, and often remain a gunky mess.
Can you paint in the sun?
It’s best to avoid painting in direct sunlight, especially during the hot summer months. The heat from the sun’s rays cause the paint to dry to quickly, which can cause a number of problems – brush marks, lap marks, inadequate adhesion. Move around the house to avoid the sun as much as possible.
