When sealcoating a driveway usually works in Fresno
- On 1991–2020 averages, Fresno has normal highs of 55°F or warmer with normal lows of 50°F or warmer, the temperatures driveway sealer needs day and night, in April–June and September–October.
- Of those months, September averages the fewest days with 0.10" or more of rain (0.2), which matters because sealer needs about 36 rain-free hours to cure.
- In November–March, afternoons are warm enough but normal lows drop below 50°F, so the sealer may not cure overnight.
