I do not know what the "wet bulb" equivalent of that is 40 deg c at 60% relative humidity is about 31 degrees "wet bulb". 35 deg c wet bulb is around 40 deg c

I do not know what the "wet bulb" equivalent of that is 40 deg c at 60% relative humidity is about 31 degrees "wet bulb". 35 deg c wet bulb is around 40 deg c at 95% relative humidity, or 45 deg c at 60% relative humidity. At 20% relative humidity a wet bulb temperature of 35 would mean an air temperature of almost 60.
