Hot and cold sands? Answered

How is it possible that some beaches have hot sand and others have cool sand even in tropics?

From experience I can say that neither the color nor the grain size matter when it comes to the temperature of the sand.
The only factors are the sun and the water.
If a beach is very flat then of course there is little distance to the water level if you straight down - it appears relative cool especially when close to the water line.
On a high beach with some dunes but little vegetation you have little chance in the afternoon to find any wet sand unless you dig deep - the sand will be damn hot.
Down here this can be so bad that you need something on your feet if you are not used to running barefoot in the middle of the road during the summer...
IMHO the worst time is late afternoon on an incoming tide.
Here the sand was exposed all day and the water to evaporate is gone while the sun is still heating it more....

If exposed to sun all day rather then submerged under cooler water

If your in a volcanic area like New Zealand it may be heated by under ground hot volcanic springs

The makeup and color of the sand can cause this.

Dark volcanic sand can be hot and light coral sand can be cool just by the way they absorb the sun. Add to this the temperature of the water under the beach sand heating the sand or cooling the sand and you have a great variance in temperature from one beach to another on the same island in the sun.
