The summer nights are cool and breezy. Fall is long and lasts well into November with some rainy weather. We usually have snow at Christmas, but not always. The snow depths are moderate and most areas don't require plowing. The Valley floor is usually clear of snow or at a depth of 4-6 inches with lots of snow in the higher elevations for recreation and stream flows in the summer.
Spring is a teaser.
Warmer days followed by cooler ones. Bring your fleece and don't pack your turtlenecks away until April. The Bitterroot Valley is a place for flannel shirts and sweaters, hiking shorts, fleece and jackets. But there is such an abundance of water in the Valley and it is so well distributed that the area looks like a sunny oasis. Come and see for yourself.
