Users of Windy: why do you want historical weather data?
-
Nice one @mhaberler, sounds like you know your stuff! The Föhn effect is a really tricky beast to forecast; actually, pretty much all mountain-based phenomena in general are a nightmare to get right. As people rely more and more on the models, the forecasters who can actually understand and predict this stuff become a dying breed... But that's a general thing, and for the marjoity of these phenomena, it's only the pilot that will ever see it, not the weather models, and not the observations network. So historical data wouldn't be much help anyway right? But then again, the charts can certainly show you the right conditions for these things to form. If pilots had a medium to add in local scale phenomena that they saw on a flight to a historical chart, that would be pretty cool. That way, they could reference what they saw when that setup reoccurs. I'm getting more and more interested in creating this myself...
By the way, with the aviation briefs, what's the "aviation briefing website"? Could you give me a link? Also, I just spent some time on working on my skewT platform tephigrams.org over the weekend, some vertical profiles, if it helps at all.

@johnckealy yes, historical data for would not be relevant back more than a few days. But then I am just an amateur pilot.
aviation briefing: well Air traffic control organsations run weather briefing and flight planning services, like for instance Nav Canada - I guess in the UK it's https://www.nats.aero

@johnckealy I see this thread is a bit old, but thought I would respond anyway. As an aviation accident investigator most all of my work is forensic in nature, and the ability to efficiently pull historical weather information is extremely valuable. Always looking for more "tools" to put in my toolbox, I really like how intuitive and simple to use this application is, and I can load up a flight track from radar or ADS-B in a matter of seconds. With historical weather information available, I can get a "quick look" at the weather at a particular time of an accident flight track in seconds and make this information available to other investigators responding before ever even arriving on site. Absolutely invaluable. Just thought I'd chime in and let you know maybe something some don't think too much about!

As a backcountry skier, being able to review the last 24 – 72 hours of wind history would be extremely helpful to understand where I'm likely to encounter slopes that have been wind-loaded with snow. This is frequently a major route planning consideration. Would be happy to pay for this as a "premium" feature.

very simply to plan a long passage. eg .shall I do it in may or september?

@Mais78
With the purpose of long passage, you better use the Pilot Charts, which give a probability of wind and current month by month. -
If historical model data would be available, I’d use them for evaluating in retrospect which model would have given me the best forecast. In my case data for the last week would suffice for that purpose.

In this case you could use the Observation vs Forecast feature. The forecast was displayed at same time with observed wind and temperature during several days. Unfortunately at the moment the past forecast is shown only for few hours. But this feature should be back in future.

Thank you very much—got it, works.
Btw, I didn't realize this was an old thread already but it was my first post here and someone else had pushed this topic to the top :)

Really late chiming in but just wanted to say this is a fantastic discussion and really enjoyed reading it. :)
A slightly different usage that I'm more familiar with is to understand building energy consumption in relations to weather, for instance for electricity demand prediction and building energy simulation. Weather is such a big driver in this area that without historical weather data, it would be very difficult to plan and design critical infrastructures (buildings, electricity grid) that we all depend on.

Hi dear admins,
on 10.10.2021 (afternoon) we sailed over Kvarner bay in Croatia.
There exists a virtual Spot named "Virtual Buoy Northadria".
As we had pretty high (but aible to sail) waves, I'm curious about the values of wave hight.
Just to compare experienced waves to forecasts in future trips.
(We had no internet connection at this time.)Is it possible to get these values?
Thanks a lot in advance

@nickis Hello, it is not possible, we do not store any historical data at the moment.

@korina OK, thanks. Then I will stop searching.
Anyway, thank you a lot for your job!!
