What is that going to do to the 2021 grape harvest and all other crops? The last time California had a record-breaking heatwave, it came at harvest time in September 2017 and turned the grapes into raisins.
Update 28-06-21
It's hit as predicted and it is unprecedented. Portland, Oregon reached a temperature of 112 degrees Fahrenheit (44.4 Celsius) on Sunday, breaking the all-time record of 108 F (42.2C) which was set just a day earlier. Seattle this 104.
When temperatures reach this high, grapes shut down to conserve water. If this continues, mitigation strategies will have to be implemented.
