You add up all the average temperatures of the days in the month and then divide them by the number of days. I'm going to give you an example but in order to make it easier on myself I am going to make this month only 7 days long. (Hey I'm 12 and I don't like adding so gimme a break) 1: 47 degrees F Okay, so you add that all up and you get 340. Now 2. 49 degrees F because this is a 7 day month you'd divide that by 3. 51 degrees F 7. And you'd get 49 degrees rounding up, so your 4. 43 degrees F average monthly temperature would be 49 degrees 5. 46 degrees F 6. 50 degrees F 7. 54 degrees F You add up all the average temperatures of the days in the month and then divide them by the number of days.
