I'm not entirely sure what data you need, but you may be able to find something useful from other listing sites (depending on your property).
We looked at Sykes, Blue Chip and a couple of others and they provide (free of charge) a model showing occupancy and rates over a 12-month period. They do this based on the performance of similar properties in the area, I believe.
I suspect if you asked nicely, there would be a host near to you who could give you details of their occupancy. You can always look at calendars to see how busy they are (though remember, they may have blocked dates for their own use). You can also see how Airbnb's own push pricing changes property prices if you pick different weeks of the year.
Hope this helps.
