This is actually the reason why Miami is one of the few major American cities that's never broken 100 F in recorded history. When temperatures rise significantly above 90, then the chance of rain goes to 100%, which cools things back down. It's pretty much why you get clockwork torrential downpours every afternoon in Florida summers.

Tampa has that distinction for the same reason too. Afternoon thunderstorms can cause the temperature to drop sometimes by 20 F!

Singapore, on the equator on the end of a peninsular and surrounded by the sea, has a record high of just 37C (98.6F), lower than the record highs of Finland, Sweden, the UK, Japan, Korea, Russia etc.

The Maldives, also known for being reliably warm and just 4 degrees north of the equator, has a high even lower, 34.9C, only a handful of countries have a high of lower than that (Iceland and Greenland being two)

Of course they also have the highest record low temperatres (19C and 17.2C each)

Yep, loved Clearwater Summer rains and thunder. :)

Would you minding explaining the phenomenon in a bit more detail, if you could?

I thought that as air temperature rises, the air is able to absorb more heat, not less. And I thought rain was essentially the fact that there is too much moisture in the air, so it condenses. So this is counterintuitive to me (but I am likely missing something).

[rini17]

The warmer air over land rises up, cooling in the process. But then water in it condenses and gives up heat, that supports the upward flow. So it's kind of runaway process. Eventually when there's too much water condensed, then it overcomes the upward flow and rains down.

How it happens, and whether it happens at all, whether the rain won't evaporate in midair etc. depends on variety of conditions.

Ohhh that makes sense. And since they are so close to water, there is always an amount of humidity in the air too I suppose.

Thank you for the explanation!

Dubai is on the coast too, though. So there's something else going on. My guess is the dry sand might be a moisture sink and vegetation itself often puts out and collects a lot of humidity, but there's not as much around in Dubai.
