May is even much hotter; the average temperature during the day changes from 18 °C (64.4 °F) to 26 °C (78.8 °F). The days feel hot but the nights are cool. It is sunny on most occasions, but sometimes it rains and drizzles. The month sees high humidity, so please remember to close the windows and stay dry when outdoors. A light, long-sleeve T-shirt and jeans may be excellent choices for the month.
National Labor Day takes place on May 1. People all around the world may seize this golden week opportunity to enjoy a trip outside. But the city will be crowded and flights are hard to book.
