Reading the pattern

This is what happened in past winters, not a forecast. Cold snaps, supply problems and crude oil prices can move any single season against the pattern, and propane also follows crop-drying demand in the fall and export markets.

Many dealers offer pre-buy or capped-price contracts in late summer. Whether they pay off depends on the winter that follows; the season chart above shows how far prices have moved in past years.
