Key Benefits

Weather Information in the Long Run
Weather forecasts have a relatively short range for planning outdoor activities. They usually extend a maximum of two weeks ahead. When information about probable weather further ahead is needed, climate data is used instead of a forecast. Sometimes these can be combined into a "45-day forecast", where the latter part of the forecast is actually climate information dressed up as a realistic looking forecast. For websites wishing to inform their visitors about likely weather months in advance, the climate data provides an attractive solution. For consumers, information about precipitation and temperature is especially interesting for travel planning. If a business needs to make a decision based on what the weather will be like in two months, that decision should be based on climate data.
Climate data is available via the Weather API for any inland location specified by latitude-longitude coordinates and for over 150.000 named locations worldwide. Custom batch deliveries are also available.
Ready-Made Tables
The data can be delivered as numbers (JSON, XML, CSV) or as ready-made graphical tables. Foreca's ready-made climate data tables are very easy to add to your website. All available locations are included in the standard package and customers can choose which locations to show. The tables are hosted by Foreca and are placed in an iframe on the customer's site.
