I'm wanting to get up early some morning to take some insect pictures covered in dew.
I'm trying to understand how to predict which morning I should get up early to do this - is the dew point, combined with the overnight low temperature forecast the way to tell this ? |

| Check your local weather bureau to see what the dew point temperature is at the time you may want to photograph dew shots. That will be the temperature the due drops in the early A.M. High humidity areas due is definately more common, unless it rains. |

Doesn't work if they are older! |

I've just asked a former weather forecaster about this and I sort of understand it now. You're on the right track.
First off you need humid air. The wind direction is a good indicator of how humid the air is likely to be. For me in the North West of England, a South-Westerly wind is apparently good.
The dew forms when the *ground* temperature reaches the dew point. The ground temperature is lower than the air temperature so you're looking for a minimum overnight temperature that's close to the dew point, but not necessarily as low/the same as it.
If the air temperature reaches the dew point you get fog.
Hope this helps. If it doesn't then at least I learned something new : )

That sounds good - thank you. |

Don't know if you would find too many insects when the weather get dewey. You might want to try a spray bottle.
