Is It Sunshine
Is it Sunshine is a Google Maps mashup that can show you the weather for any location in the world. You can search the map by location or just drag and zoom the map and the weather will dynamically load for your chosen location.
The site uses large, clear weather icons to indicate the current conditions. Is It Sunshine also allows users to view the weather for the week ahead. You can view the weather for different days via the slider at the bottom of the map.
