I see a general trend on all queries peaking around March and late November. This matches what I see on retail websites I have access to the backend of.
Searches like money, sex and music are quite flat but appear to have a low profile match to this general trend.
"sun cream" and "snowman" are clear counter examples.
Looking at the detailed trafic, year per year, I can't see any such tendency. Some years, there are some bumps for sex around November or March, but never both, and their amplitude isn't bigger than the seemingly random fluctuations.
