One day this summer I measured the Womb at 109. Last week I measured the Anniversary Pool at 110 at mid day. The hot source coming into the Womb on its south side has increased from its long time 100 to 107 now, affecting its temp. The Anniversary Pool just depends on air temp, and how much hot water is divereted directly into it, or around it in the dike above the pool. Great to see you Hiker yesterday at DCHS, such wonderful fall weather : )
