It isn't growth in Tor users, since those have stayed relatively flat in the last two weeks.
And the new rate seems to be the new normal -- it's showing no signs of going back to the old rate.
I would assume it's outgoing directory stuff, since that's most of what dir auths do.
Any guesses?
In July, Tor 0.3.0 became the most common relay version in the network, growing at quite a rapid rate:

There doesn't seem to be any corresponding Tor Browser release in that timeframe:
3 July: https://blog.torproject.org/blog/tor-browser-702-released 8 August: https://blog.torproject.org/blog/tor-browser-704-released
(Our estimates suggest that half the load on directory authorities is from relays, and half is from clients.)
I wonder if the new guard selection algorithm, or some other relay change, is causing relays to download more descriptors from more directory authorities?
