Driveway Sealing Weather in Louisiana: Best Months by City

Driveway Sealing season in Louisiana, city by city: peak months, season boundaries, and annual workable-day counts from NOAA 1991–2020 normals. New Orleans leads with 175 workable days a year; Shreveport runs the shortest at 87.

Louisiana is not one climate: New Orleans banks 175 workable driveway sealing days a year while Shreveport gets 87 — a spread the table below itemizes month by month. Season boundaries mark the first and last month averaging 8+ workable days against the label rules (55–90°F, nights 50°F+).

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.

The rules behind these numbers

Typical label thresholds for driveway sealing — the single ruleset used by every check on this page.
CheckThresholdWhy 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.
