Natural Gas Seasonal Factor

This chart is from the EIA (Energy Information Administration, an agency of the U.S. government), and shows the seasonal pattern for natural gas storage. Prices would obviously move in the opposite direction. Storage capacity tends to peak around October, with gas in storage falling after that. It tends to begin rising again about April when Spring arrives and consumption of natural gas for heating wanes. This is no doubt due to winter consumption. The gray area is the five-year average range, and the red line is the current year's value.
