Humidity

Second from left=outdoors. Raleigh, NC. June 2025.

The photo above shows the indoor and outdoor temps/humidity before the heat dome here in Raleigh slightly broke. My indoor display for my rudimentary weather station tells the tale: it’s less than 45 minutes since sunrise. Outdoors on the deck immediately behind my living room it’s already in the 80’s and the humidity at that temp is still 83%, which boggles my mind given that it’s a relative humidity indicating how much moisture the air could hold. It implies the dew point is in the mid-70’s. And disturbingly, this usually runs below the official temperature a few miles west of here at the airport. The deck is shaded, the sensor is located up by the house, and our neighborhood boasts many tall trees unlike the openness of the airport environment. The A/C had been running all night, hence the basement temperature (on the far right) reading less than 65 degrees. The other two temps are in upstairs locations. Welcome to the Southern Summer, boy!
