Across Hawaii's 2 listed cities, annual workable days for exterior painting run from 83 (Honolulu) up to 196 (Kailua). Every number comes from NOAA 1991–2020 normals scored against the same label ruleset; every city name links to its live 10-day check.

If one month anchors the Hawaii calendar it's January, the statewide leader in workable days. Use this page to pick the month, then the city page's 10-day strip to pick the days — and the national exterior painting guide for the physics behind each rule.

The rules behind these numbers

Typical label thresholds for exterior painting — the single ruleset used by every check on this page.
Check	Threshold	Why 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.
