I am configuring an irrigation controller which includes a sensor to measure EVT.  
The controller uses the sensor decrease water output as a percentage of what I define as the maximum (ie my watering schedule in July)
They refer to this as 'Seasonal Adjustment'.  I need to configure the controller with values similar to those below (see attached pdf).

ZIP,City,State,    Jan,Feb,Mar,Apr,May,Jun,Jul,Aug,Sep,Oct,Nov,Dec
33122,MIAMI,FL,    50, 70, 80, 100, 100, 80, 80, 80, 80, 80, 60, 50 
30303,ATLANTA,GA,    30, 40, 70, 90, 100, 100, 90, 90, 80, 60, 40, 30 
Note:  I am on Skidaway Island; Miami/Atlanta are the only FL/GA locations provided.

I was thinking that 'monthly EVT average' would be a good basis for configuring the controller.
I may end up just using the 'Atlanta' numbers and adjusting them as the seasons progress....but was hoping someone here might have advice or a source of monthly EVT data/averages.
