The temperature range here in north MS that is best for crossing is
70o to 85o.

The humidity range for best results is probably from 30% to 50%.
The pollen grains do not open up well when you have higher
humidity as in the 60 to 80% range.
The best times are warm, sunny days with no rainfall in the forecast.
A shower later in the day or the night after a session of daubing
usually ruins things.
The best hours are from 11 a.m. to about 2 p.m., depending upon
other conditions stated above.
