I've stopped using google weather here in the UK as well because of how inaccurate its been over the past few years and have just fallen back on the BBC. Maybe its related, maybe not.

Yeah, the Met Office and BBC (which I believe use data from Meteo France) are both much more accurate for "later today" weather than Google for me in London. Google does update its forecast more frequently, and usually is as accurate as the others for the hour ahead. And the longer range 3+ day forecasts aren't noticeably worse either. It's just the intermediate 4 - 48 hour stuff that they're surprisingly terrible wi…

Since last year the BBC is back using the Met Office https://www.bbc.co.uk/news/articles/crm4z8mple3o

Why do they show different information (temperature, rain etc.) for the same location?

The only forecasted rainfall for local areas within a very short timeframe. This made it possible to utilize simple factors to predict the near future. It is built into Apple Weather after Apple purchased them.

> It is built into Apple Weather after Apple purchased them. Did Apple lobotomize the tech when they integrated it, or lose access to whatever upstream data Dark Sky had access to? Apple Weather is comically bad (though not nearly as bad as Google's weather searches).

Someone linked a ranking site in the comments here. Apple weather is one of the most accurate ones.

It’s crazy we’ll never have forecasts as good as dark sky again. What kind of magic were they doing?

here's an explanation of their 'computer vision approach' to local weather forecasts: https://jackadam.github.io/2011/how-dark-sky-works/

"We create a 3-channel image where the red channel represents velocity in the x-direction, the blue channel represents velocity in the y-direction, and the green channel represents change in storm intensity" and then use computer vision techniques to predict what happens next

Then there is an issue with the ranking. It is much less accurate than NOAA.

Reading through the paper and... This seems to be a bit of "we're throwing a _bunch_ of inputs into this machine learning set and then pulling out outputs". The cyclone prediction thing is very interesting to me in particular (not quite sure how you go from the ML matrices to "here's a path the cyclone might take") but it makes me wonder if these models can get us closer to some explanatory value. I imagine a lot of…

Sure we do, you can follow the weights so to say, to see which data turns out to be more important vs less important for predictions of a higher quality

That person is probably misremembering or looking later after the update. I pull weather data from multiple apps all the time because I’m a weather nerd and they all agree equally poorly.

My work involves parsing real-time weather data at an existential level - because our entire use case is built around providing weather-related alerts and re-routes for aircraft.

The accuracy of weather data has been largely unaffected since DOGE took hold. The reliability of the infra, however, has suffered somewhat. There are more outages now than there ever were, with a massive spike in outages, not kidding, the month DOGE was at its peak. At that time we even saw significant manifest changes - stupid stuff like clearly LLM-generated json fields that were whole sentences instead of the key/value pairs from the schema. It was a wild time.

Anyway downstream we're mostly fine nowadays. I can still follow storm tracks accurately, see real time responses, correlate with pilot reports and lightning strikes, compare with aircraft telemetry mostly favorably, etc etc. It's quite remarkable what high-end weather products are able to do, the ones you have to work for.

We do, however, merge several free/paid sources into one picture. Rarely do I find serious disagreement, but it does happen.

question for you but what weather app / tool are you using in your personal life, as someone who works in that general industry.

No idea. I built something for this though https://metaweather.com
