"Poem in October" is a 1945 poem written by Welsh poet and writer Dylan Thomas. Essentially, the poem describes and celebrates the author's thirtieth birthday. Early in the morning, Thomas decides to take a stroll by the shore, which makes him feel calm and serene but also a bit anxious. As he walks, he begins to admire nature and the colorful autumn landscape around him. He remembers his childhood and feels a bit sad and nostalgic, as he realizes that those days are long gone and he is now, officially, a mature adult.

He indicates that October is a month between summer and winter, and to be thirty means to be "stuck" right in between childhood and adulthood; during this time, we learn to slowly let go of our naivety and recklessness and accept the wisdom and the bitter melancholy that adulthood can bring. However, the author also indirectly encourages us to never fully abandon our childish spirit, as it can help us truly appreciate the world in which we live.
