Last January, http://ca.wikipedia.org surpassed the 30M montlhy pageview for the first time. Last month, they surpassed 45M according to http://stats.wikimedia.org/EN/TablesPageViewsMonthlyCombined.htm !
Catalan-speaking editors believe that the Google search box has a lot to do with this. I hope it's not a consequence of some bug somewhere.
See the very illustrative 2008-2013 graph at http://www.wikimedia.cat/2013/11/02/la-viquipedia-en-catala-cada-cop-mes-con...
This hypothetical increase in pageviews doesn't find a correspondence (yet?) in the increase of number of editors, although they had their 5+ all-time record last January:

Do you see any similarities with Wikipedias in other languages?
