In the year 2025, there are plenty of resources online that answer the question: why does my snorkel mask keep fogging up? Before my 2025 trip to Hawaii, I consulted numerous YouTube videos and Reddit discussions on this topic. Chiefly I wanted to avoid repeating my sub-optimal snorkeling experiences from the 2015 cruise trip and the 2009 trip to Trunk Bay and Caneel Bay. One regrettable aspect of these past trips was that I couldn’t stop my lenses from fogging up when snorkeling, despite having done what I perceived to be adequate preparation.

Not surprisingly, today’s online resources are actually worse than in 2009 and 2015. Blogs with insightful resources have gone dark, long replaced by either inaccessible tribal social media, or exceedingly-short clickbait clips tailored to today’s audience. Chiefly the latter peddles quick fixes showing the “hows”, but not the “whys”. The thing is, lens-defogging, like most things in life, follows Tolstoy’s law – that every happy family is alike, but every unhappy family is unhappy in its own way. There’s a long list of things that each alone can fog up your lenses. You need to remediate each and every one of them, to get to the “happy path”.

During my 2025 trip, I finally attained defogging nirvana. I experienced crystal-clear views from my mask for two hours of snorkeling at Hanauma Bay, for the first time in my life. Nobody had told me that this was the norm for snorkeling. One shouldn’t have to stand up on shallow reef mid-snorkeling to address fogs, ever. Until I had this experience, like countless new merrymakers all around Waikiki, I did not regard having to deal with fogging every 5 minutes as anything unusual.
