In an age when people prefer to quarrel about everything, Idahoans can agree on one thing. Do you dislike the weather? Wait ten minutes; it will change. That’s why it’s difficult to trust any forecast.
But it doesn’t stop the Old Farmer’s Almanac, noted for its long-term forecasts, from attempting to anticipate what will happen in the Gem State. Despite the fact that meteorological spring begins on March 1 and astronomical spring on March 20, they have already announced their ambitious spring forecast for 2025.
How Does the Old Farmer’s Almanac Make Long-Range Forecasts?
The newspaper takes pleasure in being the oldest weather forecaster in the country. According to their website, they have begun providing projections.
According to their website, they started providing forecasts in 1792. Their founder, Robert B. Thomas, was a strong believer in the capacity of sunspots to influence weather. As a result, sunspots are one of the three components of their methodology, along with predicting weather patterns and studying the atmosphere. When examining weather trends, they use a 30-year average to determine what is “normal.”
What Does the Farmer’s Almanac Say About Idaho in Spring 2025?
When generating their predictions, the Old Farmer’s Almanac divides the country into 18 distinct regions. Idaho is in region 13, which also includes the majority of Utah and Nevada, as well as areas of Washington, Oregon, Arizona, Colorado, Wyoming, and Montana. Their long-term prognosis for the Intermountain region anticipates April to be approximately four degrees warmer than typical. Given that the high in Boise today is 29, we’re fairly pleased! However, they predict that May will be roughly three degrees lower than typical. That’s a problem if you were planning to host the first pool party of the year over Memorial Day weekend.
So, what is normal? According to the National Weather Service offices that cover several of Idaho’s largest cities, the typical highs for April and May are:
- Boise had 62.3 in April and 72.3 in May,
- Idaho Falls had 57.8 in April and 67.2 in May,
- Coeur d’Alene had 56.2 in April and 65.8 in May,
- Twin Falls: 58.7 in April; 68.7 in May.
Lewiston: 62.3 in April; 72 in May.
The Farmer’s Almanac also predicts that rainfall will be above normal throughout the region. Here’s how it looks in the same cities:
- Boise received 1.23 inches in April and 1.45 inches in May,
- Idaho Falls received 1.43 and 1.93 inches, respectively.
Coeur d’Alene had 1.91 inches in April and 2.14 inches in May, - Twin Falls had 1.13 inches in April and 1.46 inches in May
- Lewiston had 1.44 inches in April and 1.69 inches in May.
