The summer season always puts upward pressure on prices for several reasons:
1. Demand (within year) is higher and is always expected to be higher than other parts of the year.
2. There are changeovers from winter blends to summer blends which have changeover costs including shutdowns/short-term capacity reductions. Further there may be more Summer blends than Winter blends in total which reduces production economies of scale and creates more inventory uncertainty.
In short, there are real cost differences and real demand differences that drive gas prices higher in absolute terms for Summer months. Likewise we see a drop in absolute annual gas prices in the Fall as demand drops pre-changeovers.
