What is the average last frost date and the first fall killing frost in the Hayward area?​
  • Cold Hardiness Zone 3b– Average annual minimal temperature is -35 to-30 degrees; 4a -30 to-25 degrees
  • AHS Heat Zones 3-4 – average number of days each year above 86 degrees is zone 3 (7-14 days) and zone 4 (14-30) Why is that important – because plants stop growing above 86°
  • Average Last Spring Frost – was May 24 to 30; now May 21 when we have a 50% chance of being above or below that temperature
  • Average First Fall Frost –was September 13-19; now Sept 26 – again a 50% change of being above or below that date.
