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 Marysville.
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.

Marysville by the numbers

Prep checklist

  1. Wait for a rising pair: 55°F+ and climbing, first night over 50°F, 36 dry hours — in Marysville that pattern lives no month clears the 8-workable-day bar.
  2. Day-before job: crack filler in every crack, so it cures before the sealcoat lands.
  3. Hit oil spots with degreaser and sweep hard; sealer over dust peels in playing-card flakes.
  4. Check yesterday, not just today: 24 h under 0.05" of rain. Marysville's August makes that nearly automatic at 20% 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 August morning coat gets the whole 78°F afternoon to break before dew.
  8. Keep tires off through the full cure — with August nights at 47°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 Marysville's spring 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 Marysville's December (66% rain days) that lookback eats most of the calendar; August 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. August is Marysville's easiest month to find that window; December the hardest.

Can you seal a driveway in the fall?

Fall is fine here when the strip shows a dry, mild pair of days — Marysville's climate rarely forces the cold-night fail that ends northern seasons.

How often should a driveway be sealed?

When the surface tells you: graying, no beading, spreading hairlines — typically every 2–4 years. In Marysville, seal before the freeze-thaw season; December averages 28°F nights that pry open every unfilled crack. Fresh asphalt waits 6–12 months.

Best month to seal a driveway in WA?

August tops Marysville's table at 0 days clearing the 55–90°F-rising, 50°F-night, 36-dry-hour stack; no month reliably together carry the season. Check the WA state page for how the ranking shifts across the state.
