Hmmmmmm.
I would look at Seoul, South Korea for Cherry Trout and Korean BBQ/OB or Hokkaido, Japan for Char, et al, and sushi/Kirin . You would be catching the tail end of the season for fish in both places.
Also, I have seen some monster Tigerfish being caught on the upper Zambezi River the last couple weeks. Maybe not a trip you want to try pull off last minute but you could if you start ASAP. If you need info for the Zambezi let me know, I fished it 4 days last summer and still have a bunch of flies and 40lbs wire/swivels you can take.

Or just fish where you are and not where you ain't….:)
