In Burbank, the label math works from April through October: that's the stretch with 8+ workable days a month against typical driveway sealing rules. The single best month is August, averaging 31 days that clear every check — highs of 88°F, lows near 63°F, and a 1% daily rain chance. The strip above runs Burbank's live forecast; the table below ranks all 12 months.

The rules this check uses

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

Figure 194 workable days a year in Burbank, spread across April through October. Shoulder months turn on the overnight rule: an afternoon at 74°F passes, but the 50°F night floor is what actually opens the season in April. For the statewide picture, the California page compares peak months city by city.

The rain odds swing hard across the year — 1% of days in August up to 22% in February. Season the plan accordingly: prep in the wet months, apply in the dry ones.

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

Burbank by the numbers

Prep checklist

  1. Wait for a rising pair: 55°F+ and climbing, first night over 50°F, 36 dry hours — in Burbank that pattern lives April 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. Burbank's August makes that nearly automatic at 1% 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 88°F afternoon to break before dew.
  8. Keep tires off through the full cure — with August nights at 63°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 Burbank's April 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 Burbank's February (22% 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 Burbank's easiest month to find that window; February the hardest.

Can you seal a driveway in the fall?

Yes, until the nights quit. The 50°F overnight rule closes Burbank's season after October; the classic October mistake is a 62°F Saturday over a 41°F night. Spring restarts around April 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 Burbank's mild winters the drivers are UV and rain, not freeze-thaw — watch beading, not the calendar. Fresh asphalt waits 6–12 months.

Best month to seal a driveway in CA?

For Burbank: August and July — August leads with 31 workable days (high 88°F, rain on 1% of days, nights 63°F). Elsewhere in CA, the state page ranks every listed city by the same math.
