We are just coming off of a jump from temperatures in the 90s to a ten day stretch of temperatures reaching highs over 100 degrees, at least half of which were 105° or beyond. The heat wave peaked on Sunday, as temperatures hit up to 110° in some places on our farms. Extended periods of high heat can have a significant impact on our crops, especially when overnight lows don’t dip down enough to give our trees and vines some relief. We typically like the overnight lows to be in the mid 60s or below during the summer to allow for color and sugar development. A heat wave like this slows our production, increases stress on trees and vines, and reduces our harvest to half days because it’s too hot for crews to harvest.
Harvest remains ongoing for HMC Farms peaches, plums, nectarines, and Flame red seedless table grapes. Ivory green seedless table grapes are on track to begin harvest soon. The forecast shows highs dipping slightly to the high 90s for a few days before popping back up into the 100s over the weekend for another five days.
