No season owns Antioch's rain: May reaches 3.7 inches across 18.0 days and January keeps 1.8 inches on 14.6, an even spread through Antioch's year. That lines Antioch up with places like Lake Catherine, IL, Lake Villa, IL and Channel Lake, IL, fed by overlapping storm tracks.

Heat-demanding starts go out a fortnight on in Antioch, after the soil warms and cold snaps clear. The season ends by early-October in Antioch, once hard frosts set back in. A creek-bottom lot in Antioch can lag Antioch's last frost 7-10 days behind a south slope.
