Driveway Sealing Weather in Savannah, GA: 10-Day Windows & Best Months
In Savannah, the label math works from April through June: that's the stretch with 8+ workable days a month against typical driveway sealing rules. October leads the calendar with 24 workable days: average high 79°F, low 59°F, rain on 23% of days. The strip above runs Savannah's live forecast; the table below ranks all 12 months.

The rules this check uses
This table is the whole Savannah check: pail-consensus thresholds, the rising-trend requirement, and a 36-hour cure standing in for the labels' 24–48 spread.
| Check | Threshold | Why it matters |
|---|---|---|
| Air temperature | 55–90°F, and rising | Checked across the working day, 8 a.m.–6 p.m., against Savannah'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 Savannah'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 Savannah garage is the contract.

The working season runs April through June — about 119 workable days a year. The edges are night-limited: label rules want overnight lows of 50°F+, and Savannah's nights only average that from April to October. For the statewide picture, the Georgia page compares peak months city by city.
Midsummer is the trap month in Savannah — 92°F average highs against a 90°F limit. The best-months table is honest about it: October beats July with 24 workable days to 0.
Savannah has a real wet/dry rhythm: July brings rain on 41% of days versus 22% in November. When the calendar gives you a November-side window, the dry-before and dry-after rules nearly take care of themselves.
The other driveway job reads differently: pouring concrete in Savannah cares about two safe nights, not rising afternoons.
Numbers above come from NOAA's 1991–2020 normals for Savannah Intl Ap, Ga Us, 11.6 km from the city center — close enough that neighborhood microclimates (shade lines, river valleys, urban heat) matter more than station distance. See how these day counts are scored.
Savannah by the numbers
- July is Savannah's heat peak: 92°F typical high, 31 days over 90°F.
- Coldest month: January — 61°F highs over 40°F nights.
- Wet-to-dry spread: 41% rain days in July versus 22% in November.
- Overnight lows clear 50°F from April to October in a normal year.
- Add it up and Savannah banks 119 workable days a year for driveway sealing.
Prep checklist
- The strip above is hunting one shape: 55°F rising, a 50°F+ night, 36 dry hours. Savannah produces it 24 days in a typical October.
- Run crack filler the previous afternoon — filler needs its own skin time before topcoating.
- Sweep to bare asphalt and kill the oil spots first — emulsion won't bond through either.
- Confirm the lookback: under 0.05" of rain in the prior 24 h — after a July shower (41% of days), cracks hold water longest.
- 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.
- Morning start at the garage end, working toward the street — Savannah's October gives the coat 79°F daylight before the evening spread tightens.
- Keep tires off through the full cure — with October nights at 59°F, shaded strips need the long end of 24–48 h.

-
Edging tape
Keeps the garage slab and sidewalk edges black-free.
FAQ
What temperature do you need to seal a driveway?
The pail wants 55°F+ air, a 50°F+ first night, and temperatures trending up through the cure. Savannah clears all three reliably from April through June; outside that, January's 40°F average nights end the argument.
How long after rain can I sealcoat?
Give it a full dry day: the engine fails any start within 24 hours of measurable rain. Filled cracks dry last. Savannah's rain-day odds run 22–41% across the year, so the same rule costs different months very differently.
How long does driveway sealer take to dry before rain or cars?
Labels say 24–48 hours; this site checks 36 as the honest middle. Foot traffic sooner, tires last. Savannah's cure risk is mostly rain timing — in July, odds of a wet day inside a 36-hour window run high enough that the strip above is the only sane scheduler.
Can you seal a driveway in the fall?
In Savannah, early fall works while nights hold: the season's last reliable month is June (average low 71°F against the 50°F first-night rule). After that, warm afternoons sit on cold slabs and the cure stalls.
How often should a driveway be sealed?
Every 2–4 years, or when water stops beading and the surface grays. More often builds a peeling film; less often lets water work the cracks through Savannah's 16 sub-40°F January nights. New asphalt cures 6–12 months before its first coat — and crack filler goes in a day ahead.
Best month to seal a driveway in GA?
October tops Savannah's table at 24 days clearing the 55–90°F-rising, 50°F-night, 36-dry-hour stack; October and April together carry the season. Check the GA state page for how the ranking shifts across the state.
