Step-by-step explanation:
The term inference in writing means that what the author or the poet is saying is most likely true. In this case the poet is describing the visual and or weather-like features in the place he is envisioning.

I'm not sure if this answer is entirely correct but I hope it helps!
Have a lovely day!
