Littleton Long-Range Summer 2021 Weather Forecast

LITTLETON, CO — Ready for another prediction on what Mother Nature has in store for Littleton this summer?

The Old Farmer’s Almanac recently released its forecast for summer 2021, which officially begins June 20. While many are likely looking forward to warm days filled with camping, park visits, bike rides and barbecues, the question remains — will the weather cooperate?

While it’s too early to determine what each day will bring, The Old Farmer’s Almanac predicts that the Front Range and High Plains regions — which include Denver's metro area and Boulder — will get hot, dry weather throughout the summer. The high country, however, is expected to get many showers.

Here's the 50-day, long range almanac forecast for Littleton:

• May 13-19: Scattered t-storms, cool
• May 20-31: Isolated t-storms; hot north, cool south
• Jun 1-3: Sunny, hot
• Jun 4-12: Rainy periods north, sunny south; cool
• Jun 13-19: A few t-storms, cool
• Jun 20-30: Sunny, turning hot

Across the nation, Mother Nature will bring the heat to a significant portion of the United States, according to The Old Farmer’s Almanac forecast.

Temperatures are predicted to be hotter than normal in areas including the Atlantic Corridor, the eastern Great Lakes region and the Upper Midwest, south to parts of the Intermountain region. Parts of the Pacific Northwest, coastal California and Alaska may also see warmer temperatures.

Rainfall is also expected to be greater than normal in Northeast states, the eastern Great Lakes region and much of the West Coast. The Rocky Mountain region can also expect a wet summer.

The Almanac’s weather forecast methodology comes from a secret formula that was created by its founder, Robert Thomas, in 1792. The exact prediction process remains a secret, but the periodical discloses that it uses solar science, climatology and meteorology to make its forecasts.

The Old Farmer’s Almanac, which is not to be confused with its rival forecast predictor, Farmers’ Almanac, is North America’s oldest continuously published periodical, according to its website.

Farmers’ Almanac has also released its summer 2021 predictions. Unlike its rival’s predictions, it comes with a warning: the potential for severe storms will be higher than usual.

Summer temperatures are expected to rise above normal for about two-thirds of the country, especially in the south and east. Typically, the hottest summer weather occurs in last July or early August; this year's hottest temperatures could happen in late August and early September.

Other early forecasts for Colorado also predict hot and dry weather, and above-normal wildfire potential; however, Colorado's firefighting resources expanded after the 2020 wildfire season — $54 million has been allocated for response and prevention efforts in our state.
