The weather is becoming cool during October. The maximum temperature is 22 °C (72 °F) and the minimum temperature is 13 °C (55 °F). Generally, a light coat is enough, but you may also need a thick coat in case the weather becomes chilly. It rains less and the weather is dry. The ultraviolet radiation is not too strong, but wear sunscreen with SPF 12-15 and PA+ to protect your skin.
