Right now Random Lengths prices are up 15% from a year ago, and CME futures are up about 23% year-over-year.



There is a seasonal pattern for lumber prices. Prices frequently peak around May, and bottom around October or November - although there is quite a bit of seasonal variability.



Tariffs on lumber, steel and aluminum are impacting housing costs. And rising costs - both material and labor - are headwinds for the building industry this year.
