Today's temperature only reached a high of 76°F (~24.4°C), but it felt so uncomfortable and hot today. The humidity/dew point is a huge factor in this. With dew points in the 66°F - 68°F (~19°C - 20°C) range, it was sure to feel very sticky. It even felt more comfortable on one 87°F (~30.6°C) day I had earlier in the season, despite the dew point being at 61°F (~16.1°C).
