- Too cold to stain — daytime high only 40°F, below the 50°F minimum (even a low-temp line needs 45°F+).
- Rain likely in the 24h cure window (69% chance) — it can wash out or mar an uncured stain.
- Watch overnight dew — surface comes within 4.1°F of the dew point (margin is 5°F). Time the coat to dry well before evening.
- High humidity (94%, over the 85% mark) slows drying — keep an eye on the cure window.
Hold off. These are forecast numbers — confirm the surface temperature on-site before you start.
Why these thresholds
Stain applied to a damp or dew-wet board can't penetrate — it beads, stays tacky and flakes. Wood must be dry and stay above the dew point while it sets.
- • Surface temp must stay 5°F above the dew point through application and cure (ASTM D3276 / ISO 8502-42).
- • Air + surface in the 50–90°F band (low-temp lines to 45°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.
