To activate the feature you need to click the button "Map", which appears in the upper right corner of the map, and select the display of "Weather" (by the way, misrepresent, since "time" is the correct way the designer weather conditions at that instant).
Small icons are used to tell if there is sun, rain or if does, or if the day is presented with clouds. Beside, Google still shows the temperature in the region. It is up to user to have this information displayed in Celsius or Fahrenheit degrees (I could write without consulting the search engine, right?).
According to a statement from Google, the time information is provided by Weather.com, site belonging to the traditional weather channel The Weather Channel. For the position of the cloud layer with Google uses data from the Naval Research Laboratory in the United States. Two sources are usually reliable.
Weather forecast for 4 days
The display of weather information do not end the map with current temperatures. Clicking on the icon that shows the situation at the time, Google Maps carries a balloon with weather details for the region. In addition to the current condition, also has the weather forecast for the next 4 days and the minimum and maximum temperatures.
Google Maps still informs the relative humidity and wind speed and direction.
The next time you're planning your trip to the wonderful city of Rio de Janeiro, do not forget to consult the Maps. Or risk spending the day inside the hotel room watching the rain fall.
Google Earth, Google application available for Windows, Apple OS X and Linux offers real-time information of weather in a while. The question I have is, why it took so long to do the same with Maps?
