I am developing an iPhone app based on weather updates. I am looking for an API having the following things: temperature Rainfall UV index Wind speed Humidity Visibility Pressure Snowfall Heat Index Radiation index Dew point Sunrise Sunset Pollen Air quality Flu activity It will be really helpful if anyone can get me the info about the same. Also can anyone tell me if wunderground.com API provides all the info I need? Thanks and regards Sandipan
Wunderground.com has a great API, they have most of those things but not all of them. You might want to try weather.gov or check out one of the government's indexes of pollution information.
