I think the dewme.app nailed this on this runand matches this pond… “86°F ☀️ Dew pt.: 70°F | RunFeel™: (4/10) stifling 🤢.”  Glad it got the miles in but you could tell when the heat hit me.

A pond sits still, covered in green algae, surrounded by dense, leafy trees under a clear blue sky, with plants in the foreground.
