Hi all,
I was collecting geodata from Wikidata and showing them into a map they look quite weird... So I look at them more intensely and coords seem inverted.
Try with a simple query like: http://tinyurl.com/ht9ffj3
And check the coords on a item and on its result in the third column. The third column have Point(lon, lat), isn't it?

I wouldn’t call that a bug – it’s documented to be in that order: https://www.mediawiki.org/wiki/Wikibase/Indexing/RDF_Dump_Format#Globe_coord...
The simple value of the coordinate is the WKT string with the
coordinates… The order of the coordinates in WKT is longitude, latitude (since format version 0.0.2).

Here is some background on this issue, which may explain the confusion: http://www.macwright.org/lonlat/
