Severe Heat in Pacific Northwest Hurts Crops


United States

Green Pea harvest is now on the wind down in the Pacific Northwest.   Continued extreme heat with temperatures between 105 – 117 degrees over the last week will hurt the pea crop outcome. Green Pea conditions are not good as many fields were lost to heat.   Processors had a very difficult time keeping up with production and AAA grade peas will be short this season.  Look for replacing contracts with B and C grade peas.  Dry land pea fields are suffering due to lack of rain, and we will see over a 50% reduction on yields for those that grow on dry land without irrigation.  The pea market officially remains tight with prices on the rise.

With the high heat, processors are now worried about sweet corn pollination.    Sweet corn likes heat. Daytime temperatures of 77 degrees to 91 degrees are optimal with temperatures of 95 degrees and over decreasing growth.   This past week we have seen temperatures rise to 105 degrees to 117 degrees and this will affect pollination, but still too early to tell how much of the crop will be affected.

The 90-day outlook on weather in the Pacific Northwest looks to be a warmer season than last year.

Midwest area peas are estimated to be about 10% less in yield this season due to hot weather Harvest is now ongoing.

Outlook on Midwest sweet corn to date is average.

United States processing potatoes are now planted and potatoes in the Colombia Basin are emerging.  Early varieties are expected to begin harvest early this month.

Potatoes do not like heat!!  The extreme heat in the Pacific Northwest will surely reduce potato yields this season.   High heat causes discoloration inside the potato as well as a lower number of tubers developing.   Researchers have found that potato growth will shut down with temperatures above 95 degrees so a week or two of temperatures over 100 degrees in our potato growing regions here in the PNW will surely affect potato growth.

U.S. potato acreage as a whole is up this year, however not yet to the pre-pandemic level. 

Frozen Fruit stocks in the U.S are down 18% – 20% from last year.  To secure any U.S. offer on strawberries, blueberries, raspberries and blackberries is difficult.  

To make matters worse all throughout the Pacific Northwest fruit growing regions (Oregon and Washington) farmers are struggling due to the high temperatures.   Some fruit growers are mentioning that they may lose 50% of their raspberry crop due to the record-breaking heat wave.   Blueberry yields will also be affected but it is still too early to tell by how much.   

Cherries which are already short in Michigan due to frost and freeze conditions in April/May, will now be short in the Pacific Northwest growing areas due to the heat.  Cherries at the top of the trees have shriveled and high temperatures are known to cause the fruit to temporarily stop cell division and that could prevent them from reaching full size. 

A disappointing 2020 blueberry season for both cultivated and wild blueberries in conjunction with extreme demand has resulted in more production planned this season.   Expected production increases are up by 14% for cultivated and up 27% for wild blueberries.   However, in regard to cultivated blueberries the added increases may be hindered due to potentional crop outcome due to the heat in PNW.

Prices for all U.S. berry fruits are up and expected to continue to rise due to smaller crops last season, high demand, and struggles with the new season berry crops in Chile, Europe, and now in the Pacific Northwest.

Raspberry harvest has started in the Pacific Northwest, but processors are struggling with harvest due to extreme heat.

Blueberries for the frozen market should be processing around end of July, however everything will depend on weather going forward.


Harvesting of Broccoli and Cauliflower in the Bajio Valley has now stopped as Mexico’s quarantine becomes effective in May/June.   New season broccoli and cauliflower will commence in October/November in the Bajio Valley, Mexico.

Avocado season in Mexico runs July through end May.   A freeze this past winter could affect the volume coming out of the season later this summer.  U.S. consumption continues to increase and prices for fresh and frozen avocado is expected to increase going forward.


New Season broccoli harvest will commence this month.  


Fruit season in Chile has been very challenging.   A devasting storm at the end of January damage crops.  Grape crops were particularly hit hard, however, blueberries, raspberries and strawberries also suffered much damage. Price are up, and inventories will be very tight moving forward.   It is estimated that damages from this storm will be over US$150 million.   Current prices on all berry fruits are up due to Chile’s crop challenges, lack of labor, and high demand worldwide.


Avocado season is ongoing.  Yields and quality expected to be good, however labor costs will increase prices.   Mango prices have risen further due to small fruit size and dry weather conditions resulting in a reduced crop.  The season is now completed, and prices will remain firm.


Green peas and beans remain very short in Europe with no relief in sight.  Heavy rain and hail have hit most of Europe and crops (peas, corn, beans) are struggling as fields are too wet to harvest.  Both Belgium and the Netherlands are having difficulties with producing their crops and expectation is that we will see a 20% reduction in yields on many products.  

A 2021 spring freeze which struck across Europe has damaged most of the stone fruit crop there.   Cold and rain in Serbia has delayed blackberries, raspberry and cherry crops there by about 14 days.    Both Poland and Serbia will see reduction in their berry fruit yields for the 2021 season.   Prices are rising.


Lower volumes of raw material sweet corn being delivered to factories and tin plate prices have risen again.  Some are expecting canned sweet corn prices to be adjusted upward.


Temperatures are rising in China as Zhejiang and Fujian Province enter into their rainy season. 

Edamame and Mukimame are being processed with Sugar snap peas and snow peas completed.

Asparagus prices are higher this year due to reduced acreage, reduced volume, and higher transportation costs.

Chinese cherry crop has been hurt by heavy rain and expected yields are low with numerous split fruit.








ジャガイモは暑いのが嫌いです!  太平洋岸北西部の酷暑は、間違いなく今シーズンのジャガイモの収穫量を減らすでしょう。高温になるとジャガイモの内部が変色してしまい、また実の数も減ります。気温が35℃を超えるとジャガイモの生育が完全に停止することが、これまでの研究で分かっています。ここ太平洋岸北西部の私たちのジャガイモ生産地では過去1、2週間の気温が37℃以上でしたから、ジャガイモの生育に影響することは疑いの余地がありません。
