Lewiston sits at 712 feet -- Idaho's lowest point statewide -- in a deep river valley at the confluence of the Snake and Clearwater rivers. The Western Regional Climate Center specifically identifies this stretch of the Snake River Valley as carrying the highest annual temperature averages in Idaho.
Genuinely hot summers, with a real record-heat distinction
July averages an 89°F high and 58°F low, and Lewiston holds Idaho's 2nd-highest recorded temperature (117°F, July 27, 1939, behind only Orofino's 118°F in 1934) -- a real, genuine summer-heat consideration distinct from cooler North Idaho or high-elevation Eastern Idaho markets in this project.
Genuinely milder winters than the rest of North Idaho
Lewiston's winter lows average around 27°F, with a snow season running roughly November through March -- genuinely milder than Post Falls' or Coeur d'Alene's own North Idaho lake-and-forest climate, a real, distinct advantage for movers who want to avoid the region's heaviest snow.
Deliberately not folded into North Idaho's broader climate framing
This record deliberately does not describe Lewiston's climate as simply 'North Idaho's climate' -- its own low-elevation river-valley setting produces a real, genuinely distinct microclimate this record discloses on its own specific terms.
