Quick answer
In New Jersey the best time to paint a house exterior is late spring through early fall, on dry days when temperatures stay above about 50°F and there is no rain in the forecast. Late spring and early fall are ideal because they avoid both cold nights and peak summer heat and humidity.
Timing and prep make the difference between a paint job that lasts and one that peels in a couple of seasons.
Best months
Late May through June and September through mid-October usually offer the best balance of mild temperatures and lower humidity in New Jersey.
Weather conditions to watch
- Air and surface temperatures above the paint manufacturer’s minimum (often around 50°F)
- No rain expected while the paint cures
- Morning dew burned off before painting starts
Prep that makes paint last
- Wash and treat mildew
- Scrape and sand loose paint
- Repair rotted wood and re-caulk joints
- Prime bare wood before the finish coats

Frequently Asked Questions
Can you paint a house in the summer?
Yes, but avoid painting walls in direct midday sun on very hot days, which can make paint dry too fast. Crews work around the sun as it moves.
How long does exterior paint last at the shore?
With good prep and quality paint, many exteriors look good for years, though ocean- and south-facing walls weather faster.
Should I power wash before painting?
Yes. Washing removes dirt, chalk and mildew so primer and paint bond properly. The surface must dry fully before painting.
