Driveway Sealing Weather in Mississippi: Best Months by City
Driveway Sealing season in Mississippi, city by city: peak months, season boundaries, and annual workable-day counts from NOAA 1991–2020 normals. Gulfport leads with 138 workable days a year; Jackson runs the shortest at 98.
Across Mississippi's 3 listed cities, annual workable days for driveway sealing run from 98 (Jackson) up to 138 (Gulfport). 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, October 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 driveway sealing guide.
Cities in Mississippi
| City | Peak months | Season | Workable days/yr |
|---|---|---|---|
| Jackson | May, Apr, Oct | April–June | 98 |
| Gulfport | Oct, May, Apr | March–June | 138 |
| Hattiesburg | Oct, May, Apr | April–June | 102 |
The rules behind these numbers
| Check | Threshold | Why it matters |
|---|---|---|
| Air temperature | 55–90°F, and rising | Sealer wants 55°F and rising — pavement must be warm enough to cure the emulsion. |
| Overnight low | ≥50°F during the first 24 h | The first 24 hours of cure need overnight lows of 50°F or better. |
| Dry before | ≤0.05" rain in the prior 24 h | Asphalt must be fully dry; sealer will not bond to damp pavement. |
| Dry after | <0.05" rain for 36 h after (48 h cool or shaded driveways want 48 h) | Most sealers list 24–48 dry hours; this site checks 36. |
| Evening dew-point spread | ≥5°F from 6–11 pm | Heavy evening dew can blush an uncured sealcoat. |
| Daytime humidity | ≤85% | Water-based sealer dries by evaporation; humid air stalls it. |
| Wind | ≤20 mph (dust and debris in wet sealer up to 28 mph) | Strong wind drops leaves and grit into the wet coat. |
Always follow your product label — formulas vary. The table above is the typical range across major manufacturers, not a promise about your can.
