Temperature Results for Dog House Swamp Cooler

I ran an Onset Hobo Data Logger for 1 week to log the temperature and relative humidity for the dog house to see how the swamp cooler performed. The dogs seem to like it. When I get home they don't even come out, instead I can walk around and find both in the dog house enjoying the cool air.

The Results:

As you can see from the plot, during the hottest part of the day the swamp cooler lowers the temperature 10 degrees (Blue Line) from the days recorded high (Red Line)and the dogs have the cool air blowing directly on them. The Green Line is the % Relative Humidity.
