SEAL IT IN SUMMER. SLEEP THROUGH WINTER.
Seal coat is the least disruptive thing you will ever do to a parking lot and the easiest one to skip. Water gets into a surface that isn't sealed, and by the time you can see the damage you're not looking at seal coat anymore — you're looking at asphalt.

Common Questions
How often should a commercial lot be seal coated?
Most Southern California lots do well on a two-to-three-year cycle, sooner for high-traffic retail and drive-thru lanes. Sun exposure here is harder on asphalt than most people expect.
When is the right time of year to seal coat in San Diego County?
Late spring through early fall. Seal coat needs warm, dry surface temperatures to cure properly, so scheduling in summer gets you a better result than pushing it into the rainy months.
