[QUOTE="KPRC2, post: 50940, member: 148"] If you watch KPRC2 news then you may have noticed lately that sometimes the High Temperature for the day doesn’t actually occur until after 5pm and, often, closer to 6pm. Despite the sun being highest in the sky around noon, the heat builds all day to its crescendo in the later afternoon. In turn, the earth cools all night so that our coolest temperatures are usually right at dawn (ask walkers and joggers!). This daily lagging effect applies to our seasons, also. The Seasonal Lag Effect. You know of the summer solstice around June 20th being the longest day of the year, but yet those days of the most sunlight aren’t usually our hottest. The earth continues to build up its heat and then that heat begins to release in August and that is why August is usually our hottest month of the year. In fact, Houston’s average High temperature for June is 92.3° while July is 94.5° and August marks in at 94.9°---just slightly above.
