The rules behind these numbers

Typical label thresholds for exterior painting — the single ruleset used by every check on this page.
CheckThresholdWhy it matters
Air temperature 50–90°F (low-temp formulas from 35°F) Standard latex wants 50°F+. Some low-temperature formulas are rated down to 35°F.
Overnight low ≥35°F during the first 24 h (≥40°F preferred) Paint keeps curing overnight; a low under 40°F stalls standard latex.
Dry before ≤0.05" rain in the prior 12 h; watch back to 24 h The surface must be dry to the touch and out of a recent soak.
Dry after <0.05" rain for 24 h after Rain inside the first 24 hours can streak or wash fresh paint.
Evening dew-point spread ≥5°F from 6–11 pm Surface should stay at least 5°F above the dew point; dew flat-spots fresh paint.
Daytime humidity ≤80% High humidity extends recoat and cure times.
Wind ≤15 mph (brush only up to 20 mph) Wind dries the leading edge too fast and carries overspray.

Always follow your product label — formulas vary. The table above is the typical range across major manufacturers, not a promise about your can.
