Welcome to the Forums @Kemax! These are some environmental conditions that your tracker resists and it shouldn't be pushed to work further than that. You can find it below or in the Surge's owner manual:
Also, I'd be careful with the humidity since this can produce fog on the screen. Keep in mind that you can manually log the activities if you decide not to wear your tracker.
I hope this clarifies your inquiry.
