UPDATE: Cold Temperatures in the San Joaquin Valley
February 20, 2018
Morning temperatures in the San Joaquin Valley, California’s primary citrus growing region, dropped into the mid-20s last night, February 19. Tonight’s temperatures are expected to be in the mid- to upper 20s. Freeze warnings are in place for most of the San Joaquin Valley through Wednesday.
Currently, no problems been reported to lemon nor orange crops due to fruit maturity and high sugar content; the biggest threat is for Mandarins and Clementines, which are more susceptible to freeze damage due to thinner skin
Citrus growers are using irrigation water and wind machines as frost prevention tools to raise temperatures a few degrees, decreasing the risk of damage to their crop
Temperatures must be below 28◦ F/-2.2◦ C for a minimum of 4 hours to cause damage to crops
A heavy freeze will rupture internal cells, causing fruit to dry out and become unmarketable
