Harvesting Cherries At Night To Protecting Apples With Nets, Record Heat Takes Toll On Fruit Crop

Record-breaking heat that blasted the West over the weekend is also proving to be lethal to crops. Even with the heat breaking a bit on Monday, daily records were tied or broken over the weekend across California, Nevada and Arizona, with extreme heat also hitting Idaho and portions of the Pacific Northwest.

Much of the West and Southwest have been under a heat warning for more than a week, with more than 28 million Americans seeing triple-digit heat, including Arizona, Nevada, California’s Central Valley and even parts of Washington State.  The relentless heat comes just more than a week after the Pacific Northwest saw a “thousand year” heat wave that killed hundreds.

The heat and extreme drought conditions are also fueling wildfires, as well as causing orchards and farm workers to change their schedules in order to beat the heat. That’s as the National Oceanic and Atmospheric Administration (NOAA) says last month was officially the hottest June on record.

Trying to Beat the Heat with Nighttime Harvest

According to Reuters, the hottest days last month forced farm laborers to start picking cherries at 1 a.m., earlier than the normal 4 a.m. start. According to Reuters, headlamps and roving spotlights were used to aid the workers in an earlier start time in order to beat the daytime heat that threatened the workers’ safety. The extreme heat also made the fruit too soft to harvest during the day.

Reuters reports Northwest Cherry Growers still expects to see an average-sized cherry harvest this year.

"We think we probably lost about 20% of the crop," B.J. Thurlby, president of the Northwest Cherry Growers, a grower-funded trade group representing top cherry producer Washington and other Western states, told Reuters.

As reported on "The Packer" earlier this month, the Northwest Cherry Growers said the heat will force some growers to abandon a portion of their crop due to the damage caused by the heat. The issue surrounds quality. The Northwest Cherry Growers says fruit exposed to such a prolonged period of intense heat wouldn’t meet the stringent standards upheld by the Northwest growers. Unfortunately, that means that a few growers lost some or all of their crop this season.

The hot weather taking a toll on the cherry crop comes as USDA's latest sweet cherry production forecast showed production higher than 2020, but down 6% from what producers saw in 2019. USDA says the later blooming varieties were well behind the rest of the crop, which is already leading to lower yields.

Shipping Concerns

Also according to "The Packer," with temperatures topping 105 degrees for several days from June 27-30 in Wenatchee, Wash., shipping was also impacted by the extreme heat. Shippers said the heat wave could reduce the crop volume some and hold back sizing temporarily but expressed confidence there will be plenty of high-quality Washington cherries for retailers to promote in July and into August. Some are even hydro cooling cherries and taking other steps to take the heat out of fruit and using advanced sorting technology to send only strong fruit to market.

Eyes on the Apple Crop 

But it’s also adding uncertainty to what the Washington apple crop will produce this year. Apples are Washington’s most valuable crop, with an estimated revenue of $2 billion each year. Apple harvest is still six weeks away, but the heat has caused the apples to stop growing for now.

"We really don't know what the effects are. We just have to ride it out," Todd Fryhover, president of the Washington Apple Commission, told Reuters.

The Washington Apple Commission says growers are doing what they can to protect their fruit against sunburn. That includes using expansive nets and spraying water vapor above the trees.

USDA's meteorologist Brad Rippey expects the heat to continue in the West for the remainder of July. View his forecast here.
