Swimming Pool Temperature Graphs
The graphs below show the effect of solar radiation (sunlight) on the outside air temperature and swimming pool water temperature. The time of day, time of year and cloud cover impact the amount of solar radiation measured. Variables not shown include rain, filling the pool with city water, and when the water cooler is operating. The cooler is used to keep the pool temparature under 90.
| Solar radiation is measured in W/m2 and plotted in yellow. |  |
| Outside air temperature is measured in Fahrenheit and plotted in red. | |
| Swimming pool water temperature is measured in Fahrenheit and plotted in blue. |

The effects of the water cooler are shown in the picture below. The first 4 days are with out the cooler running. You can see that both the outside temp and pool temp are over the 90 mark. On days 6 - 9, the outside temp is well over 90. By running the cooler, the water temp was lowered at night and did not get above 90 during the day.
