California had its hottest July in 130 years of record-keeping, while Oregon and Washington recorded their second-hottest Julys, according to the National Centers for Environmental Information.

Idaho had its eighth-warmest July. All four states had below-average rain totals. Oregon had its 23rd driest July, while Washington had its 25th driest.

Average California temperatures for the month were 7 degrees above normal and broke by 1.9 degrees the record set in 2021.

Oregon and Washington just missed setting records. Oregon’s average temperatures were 6.5 degrees above normal, missing by 0.1 degree the mark set in 2021.

Washington’s temperatures were 5.5 degrees above normal, falling 0.2 of a degree short of the record, also set in 2021.

The Lower 48 had its 11th-warmest July. The two-month combination of June and July was the second-warmest on record. The hottest U.S. summer, June through August, was in 1936.

The heat affected some crops, the USDA’s National Agricultural Statistics Service reported. In Oregon, berry crops had generally a good year except for some blackberry varieties impacted by the heat.

Temperatures moderated in late July, but the heat continued to take a toll on crops and pastures in northeast Washington, the agency reported.

The federal Climate Prediction Center predicted Thursday sea-surface temperatures along the equator in the mid-Pacific Ocean will stay near normal the rest of the summer.

The temperatures have a 66% chance of cooling and for a La Niña to form sometime between September and November, according to the center. There’s a 74% chance La Niña will be in place between November and January.

Storm tracks influenced by La Niña generally lead to more snow in Washington. La Niña also could increase rain and snow in Oregon, Idaho and California.

The U.S. Drought Monitor reported Thursday that 63% of Oregon is in some stage of drought. Drought covers 44% of Washington and 42% of Idaho. Only 5% of California is in drought.
