How can I access historical data?

You can find a nearby PWS and see if the log data to the CWOP Network which than that data ends up in different networks like Meseowest , NWS, and even here in Windy... Lots of Applications use this data source...
I also log data personaly on my site:
I hope you find somebody near you that does the same!
QUITE an amazing number of detailed responses, so thanks.
I found that clicking on the clock in the UI while using the "Rain Accumulation" button, it states as you said, 'a forecast of what the rain accumulatION will be for the next 12, 24, etc. hours/days', (and NOT the rain "accumulatED").
However, when just clicking on the clock while using the more common "Rain, Thunder" button, it says that it will show at least some history: "Rain/snow accumulation in the last 3 hours." Of course, it is only updated every 12 hours at around 4:30 PM, in the middle of our most likely rain period, so it isn't extremely helpful. But, it was showing me some of what I wanted yesterday at that time, right after most of the rain was over.
It seems that if ECWMF has that past history, it is possible that they could make it available for the past 12 hours, instead of just 3 hours, and then present the last 12 or 24 hours of rainfall. That would accomplish most of what I'd be looking for -- a rough estimate of past rainfall.
I have been using a PWS that is about a mile from me from WU, which does an OK estimate. And I agree that I really should put out a gauge, but correct placement away from walls is difficult but vital.
I'm thinking it would be cool to put an unobtrusive gauge on one the side of my mailbox, which is about as is isolated away from obstructions as you can get. Then just check/dump it when getting the mail.
@ivo Perfectly understandable. And I'm circumnavigating the Chesapeake Eastern Shore in June and could use historical data. Any time you're ready I would pay for access to 10 year averages or a sliding history.
that is hilarious, there is massive difference between a flash stick that can stop working in 10 min time as apposed to infrastructure quality data. To create the corporate or redundant hardware to store terabytes of data is massively costly when you start looking at redundancy.
Hi how can I get 2019.01.01 2019.06.01 data.
Please reply my email firstname.lastname@example.org

@Amartuvshin not possible
Yes you can accesss there is an article about How can I access historical data?
@A-Former-User said in How can I access historical data?:
Such data does not really exist. At best you could use your local met office's logged rainfall observation stats. That historical information will exist and you can probably access it with one mouse-click from your toolbar once you find a link to it.
I get it locally with daily totals for the past three days, but it contains a link to monthly, seasonal and annual logs also. To access to them all I have to do is double-click on the radar's data icon at my radar site, and it gives the current logged data for the past three days in 30 minute blocks.
Which gives you this:
Which page contains another link to all the data for the prior months and years at the same and/or surrounding area's logged sites:
But rainfall is highly variable and what falls in the met office's gauge may not show up on your fields. But if you compare surrounding site totals you can tell how widespread or localized a rainfall event was and the implied average for your farm's area.
So check your national weather service website for links to the logged data for your local area.
But your best bet is to simplify all this by buying a capable digital weather station for your farm (and claim it as a business expense for tax deduction purposes). Such can auto-log rainfall data into a file internally that you can then download and look at in graphical form using the software that comes with the weather station.
Yes agreed Thanks for posting that out!
Historical data would be very useful indeed! Especially for winds.
