24 hours of air and pond temperature

I thought I’d share this nice looking 24 hour plot of air and pond temperatures. [Click the graph to get a clearer picture].

The green line is the slightly warmer new pond – out in the open, and in full sun.

The blue line, the shady, cooler, old pond.

Red lines are air and ground temperature.

During the warm middle of the day you can see the ponds very slightly warming up.

Both ponds are still completely ice-covered, except for a small sheltered area under bushes on the old pond.
