Bike with a Thermometer

When Bill and Jeremiah at Bike Line put my new bike together, they insisted I get a cycling computer with a thermometer built in. Today I rode a lot all through the day so it's a good opportunity to track the temperature as I ride.
Total miles: 42
Highest temp: 126
Lowest temp: 88

0545--I ride from my CHU (Containerized Housing Unit or trailer if you prefer) to the House of Pain Gym. I am Pace Bike for the weekly 5k race. Temp is 88 (all readings in Fahrenheit). I am wearing Army PT shorts and t-shirt.
0600--Race begins. 90 degrees.
0620--Race ends. 92
0630--I ride the 10.7-mile loop around post. Begin temp 92. End temp at the DFAC (Chow Hall) 99 at 0710.
0745--105 degrees. I ride to my CHU, shower and change and go to the company headquarters.
0900--ride to company headquarters. 108 degrees wen I leave, 109 when I arrive, 1.5 mile trip. Uniform is ACU (fatigues) with rifle and pack.
0930--ride to south side of base for 1000 meeting. temp is 110 when I leave. Uniform is ACU (fatigues) with rifle and pack. Same uniform for the rest of the day.
1000--lock the bike before the meeting. Temp is 113.
1245pm--finished meeting and follow-up appointment for my heel. (Keep stretching sergeant!) 122 degrees. Ride 1.5 miles to DFAC temp is 124 when I arrive.
130pm--ride to main area from DFAC. Start temp 122. High temp on 3-mile ride 126.
2pm--ride to motor pool. 122 degrees. By the end of the 1/2-mile trip, 124 degrees. Uniform is still ACU (fatigues) with rifle and pack.
530pm--ride from motor pool to coffee shop. 1 mile. 109 degrees.
615pm--ride around post. Back to PTs (shorts and t-shirt. ahhhhh!) 108 degrees
710pm--get weapon, ride to supper. 104 degrees. (sunset in 10 minutes)
815pm--back to the CHU 99 degrees.

Each time I ride in midday the temp goes up as I ride. It seems that the bike suffers the same fate as my hands--above 115 degrees the breeze makes my hands feel warmer because it is hot air blowing on me. When I ride in the morning and evening, I average about 16mph on the mountain bike and 18mph on the road bike. At midday, I ride between 9 and 11 mph unless the winds are high like today, then I ride 7mph into the wind and 15mph with the wind at my back. No hard efforts when the temp is above 110.
