The rules this check uses

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

Figure 132 workable days a year in Hampton, spread across May through October. Shoulder months turn on the overnight rule: an afternoon at 76°F passes, but the 50°F night floor is what actually opens the season in May. For the statewide picture, the Virginia page compares peak months city by city.

Pouring before you seal? Concrete in Hampton trades the pavement-warmth rule for a 48-hour freeze watch.

Hampton by the numbers

Prep checklist

  1. Wait for a rising pair: 55°F+ and climbing, first night over 50°F, 36 dry hours — in Hampton that pattern lives May through October.
  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. Check yesterday, not just today: 24 h under 0.05" of rain. Hampton's October makes that nearly automatic at 24% rain-day odds.
  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. Start early at the top of the slope: a September morning coat gets the whole 79°F afternoon to break before dew.
  8. Keep tires off through the full cure — with September nights at 65°F, shaded strips need the long end of 24–48 h.

FAQ

What temperature do you need to seal a driveway?

55–90°F and rising, with the first night at 50°F or better. The 'rising' part is why Hampton's May start matters: sealing on the front of a warm spell, not the back. Pavement lags air — a shaded slab can fail a passing afternoon.

How long after rain can I sealcoat?

24 hours after the last 0.05"+ rain, and only once cracks and shade strips are visibly dry — asphalt pores hold water after the surface grays out. In Hampton's January (34% rain days) that lookback eats most of the calendar; October barely notices it.

How long does driveway sealer take to dry before rain or cars?

Plan 36 rain-free, car-free hours (labels range 24–48; shade and cool nights need the long end). A 0.05"+ shower inside the window streaks the coat gray. October is Hampton's easiest month to find that window; January the hardest.

Can you seal a driveway in the fall?

Yes, until the nights quit. The 50°F overnight rule closes Hampton's season after October; the classic October mistake is a 62°F Saturday over a 41°F night. Spring restarts around May when pavement warms.

How often should a driveway be sealed?

When the surface tells you: graying, no beading, spreading hairlines — typically every 2–4 years. In Hampton, seal before the freeze-thaw season; January averages 32°F nights that pry open every unfilled crack. Fresh asphalt waits 6–12 months.

Best month to seal a driveway in VA?

For Hampton: September and August — September leads with 22 workable days (high 79°F, rain on 26% of days, nights 65°F). Elsewhere in VA, the state page ranks every listed city by the same math.
