Dew point is a term that gets thrown around a lot when talking about weather, humidity and comfort. But what does it actually mean?

Dew point is the temperature that water condenses at, and is usually the reason you have condensation on your windows.

But dew point doesn't just tell us about condensation! It's also a much more useful measure than relative humidity.

If you'd like to find out why, check out our blog post here: https://www.smartvent.co.nz/dew-point-and-comfort/
