Most weather apps tell you if it'll rain. TheClimatology tells you when the sky is worth chasing. We run real atmospheric models through physics-based forecasts for five fleeting phenomena — colorful sunsets & sunrises (fire skies), sea of clouds, rainbows, and the Milky Way — down to the exact place and minute. Pick a spot, get a clear go / maybe / no-go with a quality score, and never miss the moment. Built by a photographer, backed by real atmospheric science.

Hey Product Hunt 👋
I'm a photographer, and I kept missing the good skies — driving out for a fire sky that never showed, or hearing the Milky Way was perfect… the night after. The forecast data was always there; I just couldn't read it in time.
So I built TheClimatology. It runs real atmospheric models through a physics-based algorithm for each of five fleeting phenomena — colorful sunsets & sunrises, sea of clouds, rainbows, and the Milky Way — and gives you a simple answer for the exact place and minute: go, or don't.
What's different: it's not a generic weather app. Every phenomenon has its own model (cloud height, light scattering, aerosols, moon phase…), shown on a map for any location.
Would love your feedback — which sky event should we forecast next? And if you catch something good with it, drop the photo below

How does the quality score actually work for things like Milky Way clarity — is it pulling real-time satellite data or running its own model off atmospheric conditions?

@nimet3paw It's pulling real-time data and the algorithm calculated it with certain variables according to physical rules. For example cloud cover, visibility, and so on.

Finally a forecast tool that gets why I drag myself out at 4am. Tried it for the Milky Way near Tahoe last weekend and the quality score nailed the conditions better than any clear sky chart I've used.

@maddoxmara65205 Thanks Mara, you can also try other models, sea of clouds also works perfectly in seaside California. Let me know if there are any questions!

The Milky Way score is what got me — finally a forecast that tells me when to drive out instead of guessing and getting skunked. The sunset quality rating feels surprisingly accurate from the few spots I checked.

@fatihpeketekno Thanks Faith!! Also try other models, they can give you a lot benefits when you plan trips!

Love the focus on actually chasing the moment instead of just dodging rain. Quick question though, how does the quality score actually work for sunrises since the light can shift so much minute to minute, is it based on cloud cover alone or are you factoring in stuff like atmospheric particulates too?

Love that this was built by a photographer who clearly chased enough bad sunsets to know exactly what data actually matters. The go/maybe/no-go with a quality score is such a smart call, way more useful than a generic percentage.
