Boise just broke a century-old rainfall record — after a historically dry winter
Boise residents may be feeling some weather whiplash.
After experiencing its driest winter since 1934, the area has been hit with the wettest April in history.
The National Weather Service said Boise received 0.87 inches of rain Wednesday, which made this month the wettest April recorded in Boise, with a total of 3.87 inches, according to the service. And there’s still a week left in the month.
The previous record was 3.34 inches in 1912 — 114 years ago.
Bogus Basin had 16 inches of snowfall on Wednesday. The mountain has received more than 20 inches of net snow in April, according to National Weather Service meteorologist Sophia Adams. That number accounts for some melting.
“We’ve had several successive low-pressure systems that have moved in from the eastern Pacific that have brought above-normal moisture to the area and significant rainfall,” Adams said by phone.
It was a little bit of a respite to those worried about the snowpack and lack of precipitation in Southwest Idaho. The 2025-26 winter had the lowest snowfall recorded, Adams said.
“Our long-term outlooks that we typically use from the Climate Prediction Center actually had us in better chances of slightly below-normal precipitation,” Adams said. “But that ended up obviously not being the case” for April.
There’s still a chance for more rain this month, about 10% to 20%, with Sunday or Monday the likeliest days, according to Adams. The mountains have a higher probability of precipitation, with weather experts predicting a 20% to 40% chance in the Bogus area.
