Not sure for Central Europe, but for the UK, their app has logos for the Weather Channel, along with BreezoMeter for air quality info. Doesn't feel as accurate as the Met Office's app, but not too bad (tends to over predict chance of rain).

Are you in iOS 16 or iOS 15 - in iOS 15 the Weather Channel logo shows in all countries.

iOS 15 - interesting, assumed they’d only be attributing data they were actually using!

Apple’s forecast does vary slightly from the ones the BBC (using MeteoGroup) and the Met Office give, so I’m not sure what their source is if it’s not the weather channel.

I always wondered how DarkSky got that "hyperlocal" weather data. After getting into amateur radio and learning about APRS, I'm thinking they used APRS weather beacons to obtain that data. If not, it sure would be good source for very localized weather in an app.

The Norwegian Meteorological Institute has an excellent free HTTP/JSON weather API that covers the globe. No signup required. https://developer.yr.no

New Zealanders pay taxes for a weather agency and a separate climate agency, neither of which provides weather local for most farms (one farm client of my agtech automation business is an hour from town; the weather report only applies to town). Additionally, the weather service is a "state owned enterprise" expected to turn a profit. So everyone who needs farm weather uses yr.no After covid, I'm going to go talk to…

I have a weather app on Android and, as a New Zealander, wanted to include NZ data. MetService made it difficult and costly. When I asked how much for radar data, they essentially asked how much the app earned. I wrote to MP Megan Woods about this but never got a reply. Philip Duncan of WeatherWatch in NZ has fought this in the past. There is also a PriceWaterhouseCooper report on MetService:

My weather app has five weather models that cover NZ include a high resolution model from Expedition Marine, an NZ based meteorologist. I hope to bring model farming related weather data in the future.

Seems like a win/win when the customers and businesses interests align. No one is pretending Apple is a charity. Of course they do all this for obscene amounts of profit. But if we get stronger privacy as a side effect, I think that’s a generally okay situation.

We're selling our freedoms for a sense of security. Apple is almost too big to defeat. With the flip of a switch, they could turn course. (I would argue in many senses that they have.) They're already obeying local governments as a central point of censorship and control. Even the FBI/NSA has them monitoring the files on your device. Apple is too many functions wrapped up as a single legal entity. They have too much…

Sure, (maybe) a valid cause for concern. They seem to be the lesser of three evils though.

> Apples’ “privacy” is that they retain monopoly control over my data. That's a strange way to describe the situation where Apple is not allowing third parties to share your private data without your permission. Apple is doing exactly what you wanted in your first paragraph, which is to let you decide who gets access to your private data. If you only give it to Apple, that's YOU deciding to voluntarily grant Apple th…

The point is that there's no option where nobody gets to spy on me. I should have the option to host the server-side software myself, and/or delegate that to a third party of my choosing which provides a standardized API. Calling what Apple does "privacy" is a sleight of hand. True privacy means my data is mine, I am not forced to share it with whatever random employees of a multinational corporation happen to be abl…

You can choose to run your own weather data aggregation service. Just because that's something Apple is selling doesn't mean you need to buy it.

Thank you, there are so many weather API, someone suggesting a good one helps.

You say you’re trying to build a more accurate prediction algorithm to beat meteorologists. Given that goal, you should probably look to acquire a supercomputer first; tech stack wouldn’t be a concern until then.

Disagree, if he's only interested in producing a better forecast for his location.

Im interested to know how weather forecasts can be trivialised or 'simple' in other words for a local area. How is it easy to predict what happens in a washing machine of pressure systems and weather patterns split between 2 hemispheres that are in different seasons?

For our local area, it was actually trivial to develop a better weather prediction algorithm. We're not looking to build something for the whole world, which would be very difficult. At this point, I'm just trying to sort out the tech stack for the website, now that we have our prediction algorithm figured out. We'll of course optimize it over time, but even our v1 blows weather.com out of the water.

Im interested to know how weather forecasts can be trivialised or 'simple' in other words for a local area? It is still dependant on predicting what happens in a washing machine of pressure systems and weather patterns split between 2 hemispheres that are in different seasons.

I'm not sure I understand the 2nd part of your comment, but:

from first principles, coming up with an all-purpose algorithm or generally-applicable model is going to be harder than making it work for a single "use case".

for weather patterns, some parts of the country (speaking of the US here since that's where I'm familiar with) have fairly predictable cold front movements from west to east. others have ocean interactions, lake effects, etc.

Well the weather by nature is a chaotic mess of pressure systems and weather patterns, a major cause being the junction between the hot and cold temperatures of the 2 hemispheres, no?

I say 'washing machine' as it is a swirling mass of unpredictability. Yes there are obvious patterns that follow the seasons, but forecasts are required to be much more accurate than predicting the weather by patterns of the season.

They need to be accurate to each day, predicting temp, rainfall, wind etc. etc. The only way to do that is to try and predict how this chaotic system will progress over a period of time. Thats why all these weather agency talk about their new 'supercomputers' able to create more accurate forecasts. The processing power required to build these models is enormous.

No matter if you are forecasting locally or across the multiple states or countries, it still depends on forecasting the outcome of this chaotic system.
