Answer:
Unpleasantness.
Explanation:
Based on the context of this passage, one can conclude that the word inclemency, which refers to the weather, means unpleasant, that is to say, it is making reference to a kind of weather that is not mild or tempered, and that it would make any excursion or time spent outdoors, like in the baths mentioned in the passage, either uncomfortable or simply dangerous. That is why the people in the passage were forced to spend a day confined to the inn.
