If it is the longest day because it gets the most sunlight why is it not the hottest on average? Why does it not correlate with the hottest day of the year?

Temperature depends on a number of factors beyond just the number of hours of sunlight on a particular day. Clear skies instead of clouds blocking the sunlight, weather patterns bringing in warm air masses from more southerly areas, a general lag as the landscape warms up from days and weeks of long days of sun.
