The rules this check uses
Typical sealer-pail requirements, applied to West Valley City's forecast above; the site checks 36 cure hours as the midpoint of the 24–48 that labels quote. Rising temperatures matter as much as the number.
| Check | Threshold | Why it matters |
|---|---|---|
| Air temperature | 55–90°F, and rising | Sealer wants 55°F and rising — pavement must be warm enough to cure the emulsion. |
| Overnight low | ≥50°F during the first 24 h | The first 24 hours of cure need overnight lows of 50°F or better. |
| Dry before | ≤0.05" rain in the prior 24 h | What fell before you start matters as much as what falls after — surfaces hold water invisibly. |
| Dry after | <0.05" rain for 36 h after (48 h cool or shaded driveways want 48 h) | The make-or-break window: rain here undoes the work, not just delays it. |
| Evening dew-point spread | ≥5°F from 6–11 pm | Heavy evening dew can blush an uncured sealcoat. |
| Daytime humidity | ≤85% | Humid air slows evaporation, stretching dry times into the risky evening hours. |
| Wind | ≤20 mph (dust and debris in wet sealer up to 28 mph) | Scored on the windiest working hour; the marginal band changes the method, not the day. |
Always follow your product label — formulas vary. Treat the table as the consensus range across brands — the label in your hand is the final word.

West Valley City compresses the whole driveway sealing year into May through June. Miss those 70 workable days and the next real window is months out: by July, average lows hit 68°F against a 50°F floor. Plan the prep work in advance and treat every GOOD chip as spendable. Neighboring towns shift by a month or more — the Utah comparison shows where West Valley City sits.
July here fails on heat, not rain: the average high of 94°F sits over the 90°F label ceiling, and 31 of 31 days typically top 90°F. Midsummer work moves to dawn or waits for June.
The rain odds swing hard across the year — 13% of days in July up to 33% in January. Season the plan accordingly: prep in the wet months, apply in the dry ones.

Climatology here is measured at Salt Lake City Intl Ap, Ut Us (10.0 km away). Treat the monthly numbers as the neighborhood average; a shaded north-side deck runs colder and damper than any of them. The exact formula lives in the methodology.

Prep checklist
- Wait for a rising pair: 55°F+ and climbing, first night over 50°F, 36 dry hours — in West Valley City that pattern lives May through June.
- Fill cracks a day ahead with crack filler so it skins before sealer covers it.
- Degrease oil spots and sweep to bare, dry asphalt — sealer bonds to pavement, not dust.
- Check yesterday, not just today: 24 h under 0.05" of rain. West Valley City's July makes that nearly automatic at 13% 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 June morning coat gets the whole 84°F afternoon to break before dew.
- Keep tires off through the full cure — with June nights at 59°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 West Valley City'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 West Valley City's January (33% rain days) that lookback eats most of the calendar; July 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. July is West Valley City'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 West Valley City's season after June; 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 West Valley City, seal before the freeze-thaw season; January averages 24°F nights that pry open every unfilled crack. Fresh asphalt waits 6–12 months.
Best month to seal a driveway in UT?
June tops West Valley City's table at 25 days clearing the 55–90°F-rising, 50°F-night, 36-dry-hour stack; June and September together carry the season. Check the UT state page for how the ranking shifts across the state.
