I moved to Littleton 17 years ago from Sunnyvale. We have here today gone tomorrow snow for the most part. 55 inches on average a season. Could snow in September or May, sometimes both
Mostly it's the 2-3 inch storm that snarles rush hour traffic, then it's gone.
Golfers have pink, green and orange balls to play in the snow.
There are several active adult communities here, in case you are looking for that type of community.
Hyatt is building a super-duper luxury condo-hotel in Highlands Ranch (which the post office calls Littleton) because Highlands Ranch is a subdivision (with 3 zip codes) and not a city.
Littleton, the city, is in Arapahoe County, unoffically it is what they call south Jefferson County and as I mentioned Highlands Ranch in Douglas County.
It's dry. Come visit with a hat, and sunscreen, drink lots of water.
