With Winter in full swing, so is the season of rather heavy dew.
Dew Point is (to put it simply) the temperature to which the air must cool to become saturated with water vapour and dew is the result of two processes: 1) temperatures dropping and 2) objects cooling down.
What happens is if the object in question becomes cool enough, the air around said object also cools and (thanks to all those science lessons in school, I remember that) colder air is less able to hold water vapour than warm air.
This forces the water vapour in the air around the cooling object to condense and, when condensation happens, small water droplets (aka dew) forms.
(That splash of pink in the dew drop on the leaf is a reflected Anthurium flower.)
The same process can be used to explain the formation of frost with one major exception – frost forms when the dew point is below freezing.
I’m so pleased it’s not that cold here this morning, although our high humidity does mean there is a lot of dew and more than just a few drops.

Happy Monday everyone 🙂
I hope it’s not too cold (or too hot) wherever you are.
