Share Article

Forecasts of the next day's gas prices in San Diego, California, will be available via e-mail commencing Monday, July 6, in addition to the National Gas Predictor newsletter already being published every day. Local editions are also published for eight other cities, and more are coming every month.

We've been remarkably successful in our national forecasts, and in the local forecasts for the first seven cities, a Web site providing short-term forecasts of changes in retail gasoline prices, has announced that the eighth city to receive daily gas price forecasts will be San Diego, California. This latest "local edition" of the Gas Predictor Newsletter will begin publication on Monday, July 6, 2009, but subscriptions are available now. The San Diego edition is the latest of up to twelve local editions planned for publication over the course of the year.

Subscriptions are strictly limited, so it is possible that all available subscriptions will be taken even before publication begins. Only 2,000 daily subscriptions will be issued. Once these are filled, no more subscriptions to the San Diego edition will be offered. These same limits apply to each of the other local edtions as well.

These forecasts are available on the Web site at about 5:30 AM Pacific Time each business day, but subscribers to the "Gas Predictor" newsletter receive the forecasts in their e-mail at about 1:00 PM the previous afternoon. That gives the subscriber plenty of time to decide whether to buy gas on the way home from work, or to hold off for a lower price tomorrow. has been publishing its predictions for the general direction of movement of gasoline prices for the entire United States since November, 2008, and they have been correct 100% of the time. The local editions, including the new San Diego edition, predict not only whether prices will change or remain the same, but also the amount of the change.

The San Diego edition joins seven other local editions already being published for Atlanta, Chicago, Houston, Nashua (NH), Oakland, Raleigh (NC), and Tampa. publishes its "National Gas Predictor" newsletter, which predicts changes in gas prices for the 48 contiguous United States. These predictions, released to subscribers each business day at about 4:00 PM Eastern Time, are based on the price of gasoline futures and on the retail prices of regular unleaded gasoline in each of twelve key cities across the country. Using a complex mathematical model, determines which way gas prices will move the next business day in each of those twelve cities, and then applies that prediction to the country as a whole. These forecasts are remarkably accurate in predicting gas prices, but only for one day in advance, and only in terms of direction.

The new local forecasts for San Diego will use the local forecasting calculation, the same that is used in the nationwide forecast. This forecast includes the amount of change, within a given range, in addition to the direction of change.

The twelve cities currently used in the national forecasting model are each getting their own local edition of the "Gas Predictor" newsletter over the course of the year. Local editions will be announced, about one per month, for the remaining four cities, one in the New York area, one in the Midwest, one in the Rocky Mountains, and one in the Pacific Northwest.

Chuck Bonner, lead analyst for, says that the GasPredictor team is very excited about the new San Diego edition. "We've been remarkably successful in our national forecasts, and in the local forecasts for the first seven cities," Bonner says, "and we're eager to share our predictions with the San Diego area."

Subscribers to the national edition of the "Gas Predictor" newsletter can convert their subscription to any of the local editions as they become available, and they are given advance notice as new editions are prepared. For instance, subscribers were notified of the San Diego edition over a week ago, so some of the 2,000 subscriptions have already been taken.
