AND YES, sorry for my terrible english. Now please help me ty
Because humidity is like 100%. The air is saturated with vapor, and evaporation becomes difficult.

Blow a fan towards yourself, or strip. Really.

SERIOUS HERE!!!!!!
I am hot thats why...
is called humidity...
That should be it.
Others on this thread have already mention the keyword "humidity", but I'll elaborate and elucidate.
Everyone sweats/perspires to a small extent naturally all the time (less in low temperatures, more in higher temperatures), even when you're not particularly hot, exercising or jogging.
It's just that at low humidity, the sweat/perspiration evaporates readily so you don't even realize there was any sweating/perspiration.
After a rain, there is a high concentration of gaseous water vapour in the air, ie. high humidity. In such a case, your naturally ongoing sweating/perspiration is unable to evaporate readily, and hence clings onto your skin as a film of uncomfortable sweat.
there is a way to cool yourself even in hot humid weather. bring rubbing alcohol. apply it to hot skin. as it evaporates, it will suck the heat off your skin, thus cooling you. a variation of that is axe brand medicated oil. dunno if other oils work but this one i know for sure cos i did it when i was in NS. of course it is not tactical (medicated oil has strong smell) but when tactical not required, i apply it.
There is one problem with using alcohol to cool yourself. Amongst the many different types of alcohols, the only one which is relatively non-toxic to humans, is ethanol. Even ethanol is slightly toxic, which is why drinking alcoholic drinks cause liver and brain damage in the long term.
All the other alcohols are deadly toxic to humans. Consuming them leads readily to blindness and a painful death.
Taxing drinkable alcoholic drinks are an important source of revenue for all governments. Hence, alcohol tax makes alcoholic drinks expensive.
But because alcohols are also needed for non-consumption purposes across many industries (eg. painting, perfume, mechanics, etc), and yet have the risk of being consumed as drinks (eg. people buy cheap alcohol from paint / perfume / mechanics shop to drink it as party drinks), hence the law of all countries specify that you need to 'denature' the alcohols sold for non-drinking purposes (eg. painting, perfume, mechanics, etc).
To 'denature' alcohol means to add poison to it, so people can't buy cheap alcohol (eg. meant for painting, perfume, mechanics, etc) and drink them. Common poisons used for such, include the toxic alcohols of methanol and propan-2-ol.
Hence, alcohol which you can obtain to, for instance, rub on your skin to cool yourself down, eg. alcohol swabs or bottles you can buy at the pharmacy, will certainly be non-drinkable denatured alcohol, which contains some toxic-to-humans chemical, eg. toxic alcohols such as methanol and propan-2-ol.
And anything you rub onto your skin, some of it will diffuse into into your bloodstream, inevitably. (This includes all cosmetics that women use, and as such women should cut down on cosmetics.)
tyty for the answer ultimaonline xD *gives u chocolate* haha ...
