This is because they work by evaporating water into the air. Yes evaporative coolers do increase humidity. If its hot and humid then not only wont the evaporative cooler work very well but it will make the air even more humid in.
Do swamp coolers work when its humid outside. Direct evaporative coolers are operating on the ability of air to chill when absorbing water. The response to that question is clear and it is yes.
Its worth noting that evaporative coolers do their best work when the relative humidity is. There is without a doubt a pervasive perception that evaporative coolers will not work in humid climates. Although in humid climates indirectdirect evaporative cooling systems hold their performance better.
Evaporative coolers work by using the evaporation of water to cool the air. Evaporation can extract the most heat when the air is dry. To say that air coolers do not work in high humidity would be unfair and literally an act of watering down their effect.
First and foremost a swamp cooler has a hard time cooling when there is too much water in the atmosphere to evaporate. Do evaporative coolers work in high humidity. Save Money Using Evaporative Cooling.

So in the dry arid. However in high humidity the effect of the evaporative coolers especially is somewhat reduced. Truth is evaporative coolers work better in drier and hotter climates because that is when the effect of introduced water vapors in the air will be felt.
The amount that the moisture content within a unit rises depends on the outside moisture levels exterior temperature the intended temperature and the type of evaporative cooling system utilized. What humidity is too high for evaporative cooling. 5 things you need to know.
The evaporative cooler can drop the temperature by 25F or more degrees. The relative humidity indicator shows how much vapor a volume of air is already holding. Throughout the years weve often heard the refrain that evaporative coolers will not work in humidity or in various areas of the world because of humidity levels.
Fill the water reservoir and give the pads time to work before turning on the fan. The general answer is Yes. But for every 1 degree swamp coolers dropped the temperature in the room they also added about 2 to 3 to the humidity.
Do swamp coolers save money. The short answer is yes evaporative cooling does increase humidity. It will increase the humidity in your home and the air will not be cooled because there is already so much water in it.
