Driveway Sealing Weather in Montgomery, AL: 10-Day Windows & Best Months
In Montgomery, the label math works from March through May: that's the stretch with 8+ workable days a month against typical driveway sealing rules. October leads the calendar with 24 workable days: average high 80°F, low 57°F, rain on 21% of days. The strip above runs Montgomery's live forecast; the table below ranks all 12 months.

The rules this check uses
This table is the whole Montgomery check: pail-consensus thresholds, the rising-trend requirement, and a 36-hour cure standing in for the labels' 24–48 spread.
| Check | Threshold | Why it matters |
|---|---|---|
| Air temperature | 55–90°F, and rising | Checked across the working day, 8 a.m.–6 p.m., against Montgomery's hourly forecast — not just the daily high. |
| Overnight low | ≥50°F during the first 24 h | The engine reads every overnight hour in the cure window, not just Montgomery's forecast low. |
| 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 | Scored on the worst hour between 6 and 11 p.m., when surfaces cool past the air. |
| 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) | Wind wrecks application first (drift, lap marks) and carries debris into wet work second. |
Always follow your product label — formulas vary. These rows are the industry-typical range; the can in your Montgomery garage is the contract.

The working season runs March through May — about 95 workable days a year. The edges are night-limited: label rules want overnight lows of 50°F+, and Montgomery's nights only average that from April to October. For the statewide picture, the Alabama page compares peak months city by city.
Midsummer is the trap month in Montgomery — 94°F average highs against a 90°F limit. The best-months table is honest about it: October beats July with 24 workable days to 0.
The other driveway job reads differently: pouring concrete in Montgomery cares about two safe nights, not rising afternoons.
Numbers above come from NOAA's 1991–2020 normals for Montgomery 6Sw, Al Us, 10.8 km from the city center — close enough that neighborhood microclimates (shade lines, river valleys, urban heat) matter more than station distance. See how these day counts are scored.
Montgomery by the numbers
- July is Montgomery's heat peak: 94°F typical high, 31 days over 90°F.
- Coldest month: January — 60°F highs over 40°F nights.
- Wet-to-dry spread: 39% rain days in July versus 21% in October.
- Overnight lows clear 50°F from April to October in a normal year.
- Add it up and Montgomery banks 95 workable days a year for driveway sealing.
Prep checklist
- The strip above is hunting one shape: 55°F rising, a 50°F+ night, 36 dry hours. Montgomery produces it 24 days in a typical October.
- Run crack filler the previous afternoon — filler needs its own skin time before topcoating.
- Sweep to bare asphalt and kill the oil spots first — emulsion won't bond through either.
- Confirm the lookback: under 0.05" of rain in the prior 24 h — after a July shower (39% of days), cracks hold water longest.
- Tape the garage slab and sidewalk lines with edging tape — drips on concrete are forever.
- Pull thin passes with a squeegee/brush combo, back-brushing the texture as you go.
- Morning start at the garage end, working toward the street — Montgomery's October gives the coat 80°F daylight before the evening spread tightens.
- Keep tires off through the full cure — with October nights at 57°F, shaded strips need the long end of 24–48 h.

FAQ
What temperature do you need to seal a driveway?
The pail wants 55°F+ air, a 50°F+ first night, and temperatures trending up through the cure. Montgomery clears all three reliably from March through May; outside that, January's 40°F average nights end the argument.
How long after rain can I sealcoat?
Give it a full dry day: the engine fails any start within 24 hours of measurable rain. Filled cracks dry last. Montgomery's rain-day odds run 21–39% across the year, so the same rule costs different months very differently.
How long does driveway sealer take to dry before rain or cars?
Labels say 24–48 hours; this site checks 36 as the honest middle. Foot traffic sooner, tires last. Montgomery's cure risk is mostly rain timing — in July, odds of a wet day inside a 36-hour window run high enough that the strip above is the only sane scheduler.
Can you seal a driveway in the fall?
In Montgomery, early fall works while nights hold: the season's last reliable month is May (average low 64°F against the 50°F first-night rule). After that, warm afternoons sit on cold slabs and the cure stalls.
How often should a driveway be sealed?
Every 2–4 years, or when water stops beading and the surface grays. More often builds a peeling film; less often lets water work the cracks through Montgomery's 19 sub-40°F January nights. New asphalt cures 6–12 months before its first coat — and crack filler goes in a day ahead.
Best month to seal a driveway in AL?
October tops Montgomery's table at 24 days clearing the 55–90°F-rising, 50°F-night, 36-dry-hour stack; October and May together carry the season. Check the AL state page for how the ranking shifts across the state.
