The weather portlet ships with two different weather data providers, Yahoo Weather and World Weather Online. Both services require an API key which can be retrieved by a self-service registration process.

Yahoo Weather

• Update 3/15/2016:  Portlet must change to support Oath 1.  See https://developer.yahoo.com/weather/.
• ToC limits usage to non-commercial use
• Key only required for location lookups
• 2000 invocations per day (Weather portlet caching reduces invocations per day)
• Much nicer icons
• Provides forecasts only two days into the future
• API key requests at https://developer.apps.yahoo.com/wsregapp/ (log in and select My Projects from your avitar image on top right)

World Weather Online

• Update 3/29/2016:  They no longer offer a free API key to new users.
• Free to both non-commercial and commercial users
• Requires a key for both weather and location lookups
• Requires 15 minute caching of each feed (already the weather portlet's default caching strategy)
• Limit of 500 requests / hour
• Provides forecasts several days into the future (configurable)
• API key requests at http://www.worldweatheronline.com/register.aspx
