At my usual spots I’ve very rarely seen dew in 20 years and only then in total calm conditions.
Thank you for your presumptions, which are completely and utterly incorrect. Last occurrence was at an elevated site, 665m ASL on a granite tor some 6kms as the crow flies from the nearest soil disturbance by humankind. Dew is not a man made phenomenon, but a result of many and varied weather conditions. Out here we also battle with frosts, which also can form mid evening. Dew rarely falls in that area prior to 9.30pm, which I presume is your bedtime, thus you haven't seen it in 20yrs. Thank you for your input, though.
