> what are your factors for deciding the best time to visit?

I used almost exclusively weather data. My scoring process is linked to near the date ranges I provide, so hopefully that is clear.

I would love to make better use of the number of people visiting. I had a really hard time getting additional travel data for what times are busiest, but I did my best with Google data. I'd even be willing to pay for tourist data by week or month, but I don't believe it exists on the scale I'd need it. If I find it, though, I'll be sure to iterate!

Good call. I changed the heading to "Australia & Oceania"
