Exterior Painting Weather in Utah: Best Months by City

Exterior Painting season in Utah, city by city: peak months, season boundaries, and annual workable-day counts from NOAA 1991–2020 normals. West Jordan leads with 123 workable days a year; Provo runs the shortest at 90.

Across Utah's 12 listed cities, annual workable days for exterior painting run from 90 (Provo) up to 123 (West Jordan). Every number comes from NOAA 1991–2020 normals scored against the same label ruleset; every city name links to its live 10-day check.

Statewide, September is the strongest month — it tops or ties the table in most listed cities. The live strips on each city page decide the week; this table decides the month. Scoring rules: methodology; the national playbook: the exterior painting guide.

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.
