The rules this check uses
The Newport News verdicts run on these rows — consensus pail numbers with one editorial call: 36 cure hours, the honest middle of the 24–48 range labels print.
| Check | Threshold | Why it matters |
|---|---|---|
| Air temperature | 55–90°F, and rising | The film (or mix) chemistry runs on temperature — both while you work and for the first hours after. |
| Overnight low | ≥50°F during the first 24 h | Curing continues after dark; the first night can undo a perfect afternoon. |
| Dry before | ≤0.05" rain in the prior 24 h | Checked backward from your start hour using the two look-back days in the forecast data. |
| Dry after | <0.05" rain for 36 h after (48 h cool or shaded driveways want 48 h) | The engine sums forecast rain hour by hour through the cure window for Newport News. |
| Evening dew-point spread | ≥5°F from 6–11 pm | When air temperature meets the dew point, water condenses on your fresh work first. |
| Daytime humidity | ≤85% | Read as the daytime maximum, 10 a.m.–5 p.m.; within 3 points of the limit counts as marginal. |
| 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.

Prep checklist
- Wait for a rising pair: 55°F+ and climbing, first night over 50°F, 36 dry hours — in Newport News that pattern lives May through October.
- Day-before job: crack filler in every crack, so it cures before the sealcoat lands.
- Hit oil spots with degreaser and sweep hard; sealer over dust peels in playing-card flakes.
- Check yesterday, not just today: 24 h under 0.05" of rain. Newport News's November makes that nearly automatic at 31% rain-day odds.
- 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.
- Start early at the top of the slope: a July morning coat gets the whole 88°F afternoon to break before dew.
- Keep tires off through the full cure — with July nights at 70°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 Newport News'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 Newport News's September (40% rain days) that lookback eats most of the calendar; November 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. November is Newport News's easiest month to find that window; September the hardest.
Can you seal a driveway in the fall?
Yes, until the nights quit. The 50°F overnight rule closes Newport News'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 Newport News, seal before the freeze-thaw season; January averages 31°F nights that pry open every unfilled crack. Fresh asphalt waits 6–12 months.
Best month to seal a driveway in VA?
For Newport News: July and June — July leads with 20 workable days (high 88°F, rain on 36% of days, nights 70°F). Elsewhere in VA, the state page ranks every listed city by the same math.
