If you've ever driven from the Mission to Ocean Beach and felt personally betrayed by the weather, someone finally built a tool for you.

A local developer just launched bayfog.app, a real-time fog tracker for the Bay Area that updates every 10 minutes using public satellite imagery. The concept is dead simple: check the map before you head to the beach, lace up for a hike, or commit to that cross-city drive, and actually know whether you'll be greeted by sunshine or Karl's cold, gray embrace.

Here's what we love about this: it's a self-funded side project. No VC money. No subscriptions. No harvesting your data to sell you fog-resistant jackets. Completely free, completely private. The developer openly admits other fog trackers exist but wanted something with better design and image quality — and honestly, that's the kind of competitive instinct we wish we saw more of in government services.

Think about it. SFMTA can't build a functioning bus tracker app without burning through millions in public funds. Meanwhile, one person with satellite data and some free time builds a genuinely useful weather tool on their own dime. It's almost a perfect metaphor for the gap between what individuals can accomplish when they're motivated versus what bureaucracies produce when they're spending other people's money.

The practical applications are real, too. San Francisco's microclimates are legendary — it can be 72 and sunny in the Castro while Sunset feels like a scene from The Mist. For anyone commuting, planning outdoor time, or just trying to figure out which neighborhood to grab lunch in, a ten-minute-refresh fog map is legitimately handy.

We'd love to see more of this kind of thing: lightweight, useful tools built by people who actually live here and understand the problem. No grants required. No blue-ribbon commissions. Just someone scratching their own itch and sharing the result.

Bookmark it. Karl isn't going anywhere, but at least now you can see him coming.
