The calculation is done on a day-by-day basis. You're only showing the monthly summary. We would have to see the average temperature for each day in one of those months.
Take July. The cooling degree days for the month is shown as 33.3ºC. That could be because one of those days was super hot 18.3+33.3=51.6ºC (hot!), or it could be because all 30 days were just 1ºC above 18.3º. From what is shown, we don't know.
