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.

West Valley City by the numbers
- Peak heat lands in July: 94°F average highs and 31 ninety-degree days.
- January bottoms the West Valley City year: 39°F days, 24°F nights.
- Rain-day odds swing from 13% in July to 33% in January.
- Nights averaging 50°F+ run May through September.
- Annual workable driveway sealing days: about 70 of 365.
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.
Pro moves for West Valley City conditions
- Overnight lows matter as much as daytime highs: emulsion sealer needs about 24 hours above 50°F to cure, and one cold, dewy night can ruin it.
- Fill cracks with rubberized crack filler a day or two before sealing; sealer is a surface film and won't bridge anything wider than a hairline.
- Don't turn the steering wheel while parked on freshly sealed asphalt for the first week — stationary wheel scrubbing leaves permanent scuff marks.
- If the pavement is too hot to hold your palm on, mist it with water before sealing; flash-dried sealer streaks and peels within a season.
- In West Valley City, start as soon as morning dew burns off so the second coat is down by early afternoon, leaving daylight and warmth for curing before evening dew.

Frequently asked questions
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.
How many coats of driveway sealer do I need?
Two thin coats beat one heavy coat. Thin films cure evenly all the way through, while a single thick pass skins over, stays soft underneath, and tracks footprints. Wait until the first coat is dry to the touch — commonly 2 to 8 hours depending on product and sun — then apply the second at a right angle for uniform coverage.
Can I apply driveway sealer to a damp driveway?
Slightly damp is fine for water-based asphalt-emulsion sealers — pros often mist hot pavement first so the sealer doesn't flash-dry — but standing water is not. Puddles dilute the emulsion and leave thin, gray, fast-failing patches. After washing the driveway, let it dry until it is uniformly damp-dark with no shine, and never seal while rainwater still pools in low spots.
How long should a new asphalt driveway cure before sealing?
Fresh asphalt needs its lightweight oils to oxidize before sealer will bond. Installers and sealer manufacturers say wait at least 90 days, and 6 to 12 months is safer — many recommend letting new pavement go through a full summer first. Sealing too soon traps those oils, leaving the surface soft and prone to scuffing and tire marks. The color shift from jet black to matte gray signals readiness.
How often should you seal an asphalt driveway?
Every 2 to 3 years for most driveways — when the surface fades to gray and water stops beading. Annual sealing is counterproductive: coats build up, then crack and peel in sheets. Driveways in West Valley City exposed to harsh sun or freeze-thaw cycling sit at the shorter end of that range; shaded, mild-climate pavement can stretch a year or two longer.
Driveway Sealing glossary
- Asphalt emulsion
- A water-based blend of asphalt binder and emulsifiers used in most DIY sealers; it cures as water evaporates, so temperature, humidity, and sun control dry time.
- Tack-free time
- The point when sealer no longer sticks to a light touch — usually a few hours in sun — though full cure for vehicle traffic takes far longer.
- Squeegee coat
- A thin application worked into the pavement surface with a rubber squeegee; thin coats cure through completely, while thick coats skin over and stay soft underneath.
- Oxidation
- UV and oxygen slowly breaking down asphalt binder, turning pavement gray and brittle; sealer's main job is slowing this process, not fixing structural cracks.
- Pavement surface temperature
- Blacktop in summer sun can exceed 120°F even on an 85°F day; sealer flash-dries and streaks on overheated pavement, so pros mist it first.
- Coverage rate
- Square feet one gallon covers — typically 50 to 80 for asphalt emulsion, depending on pavement porosity; stretching sealer thinner than spec leaves a weak, fast-wearing film.
