Ask ten painters in West Palm Beach when to paint a house exterior and you will get ten answers, most of them "whenever we have an opening." The honest answer is narrower. South Florida has a real exterior painting season, and painting outside it is the single most common reason a fresh paint job peels, blisters, or mildews within two years.
The short answer: late November through April
From roughly Thanksgiving to late April, Palm Beach County and Broward see lower humidity, cooler mornings, and far fewer afternoon storms. Dew points drop, so stucco that got damp overnight actually dries by mid-morning. Paint applied at 10 AM has the whole day to cure before any moisture returns. This is when we book most of our exterior repaints in Boca Raton, Delray Beach, Boynton Beach, Palm Beach Gardens, and Fort Lauderdale.
Why summer is a problem
Daily afternoon storms
From June through September, rain is a near-daily event after 2 PM. Most exterior acrylics need four to six hours before they can take rain without washing out, spotting, or losing adhesion. A wall painted at noon that gets hit at 3 PM is a wall that gets repainted.
Humidity and dew point
Even on a dry day, summer humidity slows curing. Paint that stays soft longer picks up dirt, insects, and pollen, and it is more likely to develop surfactant leaching, the sticky streaks you sometimes see running down new paint. When the dew point is within a few degrees of the surface temperature, moisture condenses on the wall and the paint will not bond properly.
Surface temperature
A south- or west-facing stucco wall in July can reach 130 degrees by early afternoon. Paint applied to a surface that hot dries too fast, does not level, and can blister. Painters who work summer exteriors follow the shade around the house and quit early.
Hurricane season
June 1 through November 30. Nobody wants scaffolding up when a storm is forming, and a half-finished exterior with bare primed patches is exactly what you do not want going into a wind-driven rain event. A sound paint film is your stucco's first line of defense, which is another reason to finish before the season starts.
What if I need to paint in summer?
It can be done, and we do it, with adjustments. Work starts at first light and stops by early afternoon. We check the forecast every morning and skip days with a high storm probability. We use fast-dry acrylics with a shorter recoat window. We never paint stucco that is still damp to the touch. It takes longer and there are more weather days, but the result is fine if the crew is disciplined about it.
Interior painting is a different story
None of this applies inside. Interior painting is a year-round job in South Florida as long as the AC is running. In fact, summer is a good time for interior work, cabinet painting, and popcorn ceiling removal because exterior crews are slower and scheduling is easier.
How far ahead should I book?
Good exterior painters in Palm Beach County book up fast for winter and spring. If you want your house painted before hurricane season, call in the fall. If you call in March, you may be looking at May. We keep a running schedule and will tell you honestly where you would land.
