In addition the large open areas of the surface of a pond invites better airflow, and waves increase surface area. Both of these will further increase evaporation rates.
The largest impact is dewpoints. Dry air will obviously increase evaporation far more than just warm/hot temperatures.
For instance if your dewpoint is 75 degrees, and the water temp is 75 degrees, it can be windy all it wants, and nothing will happen. No evaporation.
If the water temp is 50 degrees, and the dewpoint is 75 degrees, you will GAIN water via condensation. The water will warm very quickly near the surface to the dewpoint as condensation releases quite a bit of latent heat.
But if the dewpoint is 50 degrees, and the water is 80 degrees, your water will evaporate quite quickly as well as chilling below the air temp. It may be 90, but the water will go down in temperature due to evaporative cooling.
