Fans do you no good when the humidity is above a certain point.
You’re also losing a lot of water to evaporation from sweating if it is doing anything at all.
There is a reason why Singapore switched to AC pretty much everywhere except old hawker centers, and why it’s not alone.

That would be related to the wet-bulb temperature. If the wet-bulb temperature is more than about 30°C, then I'd consider the area to be uninhabitable. (A wet bulb temperature of 35°C is considered lethal).
Fans are surprisingly effective as most people are stationary and thus produce almost a bubble of high humidity around themselves. Fans disperse that localised high humidity and allow people to effectively reduce their temperature through sweating/evaporation.

And getting worse.
