API PWS Data Is Stale

  • Problem
  • Updated 5 months ago
This evening, the API is getting stale observation data, but if I use wunderground's website the same PWS stations are reporting current data.

API call for KWARENTO85 just a few minutes ago returned observational data that is 411 minutes old (and even has the estimated flag set) but if I use the website to look at the station data ( https://www.wunderground.com/cgi-bin/findweather/getForecast?query=pws:KWARENTO85 ) the data is 2 minutes old.

(This is not the only PWS doing it, it's just a handy example.)

(Others are reporting stale data as well, out of the 5 I check only 2 are behaving normally.)

Yes, I agree to you and also have seen old observation time / date.

@Wunderground: Please fix that issue!

I concur!

For the past 4 days PWS API and wunderground.com mismatch.
It looks as though API reports for PWSs are significantly outdated.

Here's an example - a PWS of my friend Fred from Leiden, Netherlands "ILEIDEN13".
The staton is on and reporting continuously.

wunderground.com is flawless.
https://www.wunderground.com/cgi-bin/findweather/getForecast?query=pws:ILEIDEN13
Right now this link shows 10 Celcius observed 3 minutes ago.

But the API is reporting weather from 2 days ago.
http://api.wunderground.com/api/b28d047ca410515a/conditions//q/pws:ILEIDEN13.json
8 Celcius observed on November 18.
Today is November 22.

Please address this problem.
We have received numerous complaints from PWS owners.

At the risk of jinxing it - it seems to be better this evening.

The issue was resolved during the night, and we are continuing to monitor the situation.  The data is flowing correctly now and propagating across the servers so that it does not appear stale.  We are also implementing checks to make sure it doesn't happen again.

I'm seeing stale barometric pressure, winds, and precip data via the API that I don't see on the WU webpage. I also believe it is stale on temp and dewpoint, though at different times. I've seen dew point exceed temperature (impossible). This has been going on the past few days.

I also periodically get stale data, next API call its resolved. Data on wunderground.com looks fine, only data from API call is corrupted.

Here we go again, another stale data API incident, it seems to have started around 30 minutes ago.   

It's affecting the wunderground site as well, it says there are no personal weather stations in my area (and there's well over a dozen).

EDIT: May be coming back up.   Although website still can't find PWS stations in the area.)

Make sure you have added your location via Search function. It is a common mistake to rename the place.

I have a similar issue - the website shows my PWS data correctly (.3mm precip today) but the API tells me 13mm - not sure if it's stale or potentially misaligned with my timezone - I'm in Australia. API show's correct timezone info but as this is a "today" measurement I wonder if the API calculates "today" better than the api - would be nice if the site used it's own APIs so this would getsorted!
