Step-by-step explanation:
The speaker of the poem is somewhat disappointed by the rain that prevented him from enjoying the trip he had taken. That's because he didn't expect a tropical rain to arrive at the moment when he wanted to enjoy the place, explore and discover everything the region had to offer. This leaves the speaker showing a certain unhappiness, but when observing the tropical storm, he is able to perceive a beauty unlike any other in it that makes him reflect on how it is necessary to appreciate it.
