Ive never encountered "stable" weather but the moonsoons usually bring temperatures in the high eighties or low nineties with R/H in the 70% range.
But AC by itself is a loser...
I nick-named what you experienced CLAMMY HELL. Over eighty degrees. Almost intolerable without a fan. So the fan blows and the skin gets chilled and teeth get gnashed. The answer is a dehumidifier. Most folks decide on a way-too-small capacity unit. And to make things even more of a PITA, there should be good air circulation to bring moist air to the unit. Otherwise it is spinning it's wheels eating kWh.
My God. 110F with humidity over say 40% would kill people right and left. Certain areas of the world, like the Becca Valley in Iraq suffer this killer clime seasonally and somehow the Bedouins endure it. It has killed fit US armed forces personnel.
In tropical savanna country I learned a lot. First: When first turned on, A/C does zero to lower temperature. All of the energy is being used to precipitate water vapor. When R/H approaches 60% the temperature starts to drop. But then clammy hell sets in.
I can easily tolerate 85F. I love it as a matter of fact, when the R/H is below 40%
But the A/C cannot walk and chew gum. The dehumidifier if large enough extracts that magic 20% band of humidity. My 15' x 20' room dehumidifier extracts about 32 pints in a 24 hour period worst case humidity (intense rainstorm, fast clearing skies, hot sun). That's four gallons and it is transported to the hen house. The new casita will be sealed a lot better. The girls pile through the front door, conspiratorially spaced 5 seconds apart and all that work for nothing. Sigh. I need a mud room entrance.
