Understanding an Average Monthly Temperature Map
Weather maps can show temperature for one day or for each hour of the day. Meteorologists also use maps that show temperature data for longer periods of time, like a month. The April 2013 map on this page shows the average monthly temperature. The average temperature represents what the temperature was mostly like for the whole month.
This information is helpful: if you know that the average temperature for a certain month is 75°F, then you can confidently assume that there were no snowy days or very few days that you needed a coat to be outside.
