In Cranston, the label math works from May through September: that's the stretch with 8+ workable days a month against typical driveway sealing rules. August leads the calendar with 22 workable days: average high 82°F, low 64°F, rain on 30% of days. The strip above runs Cranston's live forecast; the table below ranks all 12 months.

The rules this check uses

This table is the whole Cranston 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 Cranston verdict above.
CheckThresholdWhy it matters
Air temperature 55–90°F, and rising Checked across the working day, 8 a.m.–6 p.m., against Cranston'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 Cranston'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 Cranston garage is the contract.

The working season runs May through September — about 93 workable days a year. The edges are night-limited: label rules want overnight lows of 50°F+, and Cranston's nights only average that from June to September. For the statewide picture, the Rhode Island page compares peak months city by city.

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

Numbers above come from NOAA's 1991–2020 normals for Providence T F Green Ap, Ri Us, 6.5 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.

Cranston by the numbers

Prep checklist

  1. The strip above is hunting one shape: 55°F rising, a 50°F+ night, 36 dry hours. Cranston produces it 22 days in a typical August.
  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 April shower (39% 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 — Cranston's August gives the coat 82°F daylight before the evening spread tightens.
  8. Keep tires off through the full cure — with August nights at 64°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. Cranston clears all three reliably from May through September; outside that, January's 22°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. Cranston's rain-day odds run 30–39% 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. Cranston's cure risk is mostly rain timing — in April, 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 Cranston, early fall works while nights hold: the season's last reliable month is September (average low 56°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 Cranston'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 RI?

For Cranston: August and July — August leads with 22 workable days (high 82°F, rain on 30% of days, nights 64°F). Elsewhere in RI, the state page ranks every listed city by the same math.
