What could have influenced the decision to go to the beach?

The answer indicates that the decision to go to the beach was influenced by the weather being better than before. This suggests that pleasant conditions, such as warmth and clear skies, create an inviting atmosphere for beach activities, making it a desirable outing. If the weather had improved from a previous state, it would likely encourage individuals to take advantage of the nice conditions for relaxation or recreation at the beach.

Opting for better weather directly aligns with typical reasoning behind enjoying outdoor activities, as people often seek out favorable conditions to enhance their experience.
