Gridwise is available to users only in supported cities. Some smaller towns and locations may not have local events and regional airport data. Please understand that you can not manually switch cities. Changing cities is automatically managed by Gridwise. At account registration, you will automatically be placed in the nearest supported major market. Those not within, or nearby a supported market will not be able to use Gridwise. We are expanding rapidly, so be sure to keep checking the list of available cities often!
