Is it good to paint in Providence, RI this week?
A live 7-day go/no-go calendar for exterior paint in Providence, built from the local forecast against the 5°F-above-dew-point rule. We lead with the signal a weather app misses: overnight condensation risk.

- Watch overnight dew — surface comes within 4.3°F of the dew point (margin is 5°F). Time the coat to dry well before evening.
- High humidity (91%, over the 85% mark) slows drying — keep an eye on the cure window.
- Some rain risk (35%) during the cure window — re-check the radar before you start.
Caution. These are forecast numbers — confirm the surface temperature on-site before you start.
Why these thresholds
Overnight dew condensing on a fresh coat causes blistering, surfactant leaching and peeling — the cause of 40%+ of exterior paint failures.
- • Surface temp must stay 5°F above the dew point through application and cure (ASTM D3276 / ISO 8502-42).
- • Air + surface in the 50–85°F band (low-temp lines to 35°F).
- • Humidity under 85%; ideally under 70%.
- • No rain for 24h after application.
- • We use the forecast ground-surface temperature as a surface-temp proxy — confirm on-site with an IR thermometer.
