I keep a pool thermometer in my Owner's Locker (remember "pool gate"?) It's a cheap thermometer so I don't know how accurate it is but the readings matched with my perceptions of the temperatures. Here are the current pool temperature readings as of 11am with an outdoor temperature of 79 degrees, partly cloudy skies, slight breeze:
Luna Park Pool: 82 degrees
Hot tub near the pool slide: 101 degrees
Quiet Pool: 85 degrees
The quiet pool was so nice I was tempted to jump right in in my shorts and t-shirt!
We're having a fantastic time. Weather is perfect, crowds are not too bad, ride wait times shorter than usual.
