Not an official source and that's what matters here when spreading info on the net.

But yes there are some climate boxes that have some small deviations from the data at the source.
I'm correcting those if i find them.
The Majority of the Climate Data on Wikipedia is correct and you can always check yourself and compare these normals to those from the source.




Wunderground has correct data. We are not talking about the Private Weather Stations.
One can obtain data from the official synoptic weather stations there.
Atlanta Hartsfield International Airport

I agree with this.
1981-2010 normals are more relevant to the current climate.
I think it was a pretty dumb decision from those Wikipedians.
Nope, look at the raw averaged 1981-2010 NowData. Here are the average highs for that time period, clearly below what is posted on Wiki.

Wiki data wrong for major cities!? :smack:-image.png

You're right, it doesn't but then why would it be wrong?

Again why should we use Raw data over the Official NCDC normal with smoothed data.

Compare these two:
National Weather Service : Observed Weather for past 3 Days : Atlanta, Hartsfield - Jackson Atlanta International Airport

https://www.wunderground.com/history...ic=&reqdb.wmo=

The Hourly Measurements are the same.
Wunderground uses official data.

Actually no they are correct, check Miami area average temps, they are correct for every month Same thing for miami intl. airport info, all of it is correct.

I have said it before but some Spanish towns/cities are wrong as a certain user was bumping up the figures to make them appear warmer. He also added a weather box for a locality of Valencia using just 3 years worth of data from a (dodgy) Wunderground station When I changed the figures back to the correct ones as stated on the AEMET website, he accused ME of vandalising the weather boxes & using incorrect data & the moronic Wiki mods (or whatever they are) took his side despite me telling them to check the actual sources... Frickin tw*ts The same user also changed all the Spanish hardiness zones on Wikipedia for European cities, bumping those up too

You're talking about this one: https://en.wikipedia.org/wiki/Gandia#Climate
Yes, it's absolute bull****. Official Climate Normals for Gandia don't exist in the first place.

But the Normals for other Spanish Weather Stations are correct

Yes, the NowData info is correct, that's my point.

W.U basically uses the NWS data and enters it into their system same day but guess what happens when updates and changes are made... W.U doesn't pick it up. I've seen actual Max/Min be off because they were updated with NWS the next day.


Case in point.....from most recent memory...


The NYC snowfall amount for 1/23/16 was changed to 27.3". Did Weather Underground change it for that day? Nope.... So the biggest snowstorm on record wont come up with W.U but will with NWS. (Nowdata will update in coming days/weeks, see if W.U does too. I hope they do!)


Now imagine all the needed daily adjustments after Quality Control.

NWS Changed it.





W.U still has wrong data and wont show as biggest snowstorm on record. If anyone wants to keep checking back feel free. Or good luck contacting W.U to fix it. I tried without a response or a fix. pointless using them.

Okay, Let's say Wunderground is 95% correct.
It's a nice way to get data for synoptic stations around the world, where it's not possible to get Climate data as easily as in the US.
