What makes your snorkel masks fog up?

There are a couple of things that can make your snorkel or diving masks fog up and it is important to know them so as to pay attention to them in the future.

Commonly, the fogging up of snorkel masks happens because of the condensation of water vapor in the mask.

When this happens the temperature inside and outside the lens of the mask becomes different and since moisture has to stick to a surface, it then sticks to the lens and that is how fogging occurs.

Additionally, fogging up of snorkel masks can also occur if your mask has somehow come in contact with dirt, or grease. In summary, dirt and grease can also be the chief cause of the fogging up of your swimming masks.


Fogging occurs due to moisture, so if you minimize the moisture build-up, your snorkel mask will not fog up for a very long time.
