From my experience with that scale of traffic (with Opera Mini at the time about 250M MAUs and 150k full pageloads/s): There is surprisingly little seasonal variance. You have your weekly/daily traffic rhythms based on when your users are awake/active based on their geographical distribution and that's mostly it. "World events" also have very little impact - they tend to barely make a dent in that massive background noise. Before we had large volumes of traffic I thought we'd be seeing all sorts of unusual peaks, after a few years I realized growth at scale tends to become boring (but in a good way).
