I live at the boundary between city and forests and in summer the temperature drop is really 'incredible'. The amount of energy wasted by urban areas is as much so. But at the same time it's nice because we can restore more trees for shade easily

I live in foothills of a lower range of hills (European Jura), and it has numerous effects. The air is normally blowing down the mountains towards us in the evening (katabatic wind), so it doesn't matter how hot the day was, evenings are pleasantly cool and night gets colder than expected. This wind also cools hot surfaces pretty effectively.

Even just entering a dense natural forest during the day, one can sense drop in temperature around 3-4C during summer, and increase in humidity during dry periods.

Lived in French Jura for 5 years. It is so beautiful. And I am not the only one to have noticed. The Last Man or Frankenstein have also the Jura mountains as landscape.

I miss that place... (except its prices)

I've noticed this while doing evening walk, I didn't know it was a named phenomenon.

Paragliders like me (or similar sports) have to be very familiar with meteorology and wind, its the most important but largely invisible force that can literally make you or break you.

I love that overreach expected by a passion like that, meteorology is fascinating to engineer in me and its effects are very much visible every day and affect us all.

Since I've been bike commuting I've become more in touch with climate. For the simple need of avoiding rain. You start to pay attention to wind, direction, clouds .. it's strange cause you have to think more but it's also funny because you're sharper and smarter in a way. And that's just noob / surface level :)
