Judging from this graph the temperature would be around 300K where the pressure is ~5 Atm. Pressures of ~5 Atm are found underwater on earth at depths of ~150 feet or so, which is routinely achieved by divers, including saturation divers who live at depths like that (or greater) for weeks at a time.

So definitely survivable, and even comfortable. Neglecting the chemical environment and the wind, of course. But you can be protected from a harsh chemical environment with some pretty simple coverings and depending on the variability of the wind you might be able to ride along with it in a way that's not too uncomfortable.
