The rules this check uses

This table is the whole Little Rock check: pail-consensus thresholds, the rising-trend requirement, and a 36-hour cure standing in for the labels' 24–48 spread.

Typical label thresholds for driveway sealing — the ruleset behind every Little Rock verdict above.
CheckThresholdWhy it matters
Air temperature 55–90°F, and rising Checked across the working day, 8 a.m.–6 p.m., against Little Rock'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 Little Rock'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 Little Rock garage is the contract.

The working season runs April through June — about 89 workable days a year. The edges are night-limited: label rules want overnight lows of 50°F+, and Little Rock's nights only average that from April to October. For the statewide picture, the Arkansas page compares peak months city by city.

Midsummer is the trap month in Little Rock — 92°F average highs against a 90°F limit. The best-months table is honest about it: September beats July with 23 workable days to 0.

The other driveway job reads differently: pouring concrete in Little Rock cares about two safe nights, not rising afternoons.

Numbers above come from NOAA's 1991–2020 normals for Little Rock Ap Adams Fld, Ar Us, 11.1 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.

Little Rock by the numbers

Prep checklist

  1. The strip above is hunting one shape: 55°F rising, a 50°F+ night, 36 dry hours. Little Rock produces it 23 days in a typical September.
  2. Run crack filler the previous afternoon — filler needs its own skin time before topcoating.
  3. Sweep to bare asphalt and kill the oil spots first — emulsion won't bond through either.
  4. Confirm the lookback: under 0.05" of rain in the prior 24 h — after a May shower (34% of days), cracks hold water longest.
  5. Tape the garage slab and sidewalk lines with edging tape — drips on concrete are forever.
  6. Pull thin passes with a squeegee/brush combo, back-brushing the texture as you go.
  7. Morning start at the garage end, working toward the street — Little Rock's September gives the coat 85°F daylight before the evening spread tightens.
  8. Keep tires off through the full cure — with September nights at 63°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. Little Rock clears all three reliably from April through June; outside that, January's 31°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. Little Rock's rain-day odds run 23–34% 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. Little Rock's cure risk is mostly rain timing — in May, 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 Little Rock, early fall works while nights hold: the season's last reliable month is June (average low 68°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 Little Rock's 31 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 AR?

For Little Rock: September and May — September leads with 23 workable days (high 85°F, rain on 23% of days, nights 63°F). Elsewhere in AR, the state page ranks every listed city by the same math.
