September is much cooler than the previous two months. The minimum temperate is 13 °C (55 °F) and the maximum temperature is still a high of 28 °C (82 °F). It rains less frequently during the day. Summer clothing is adequate, but in the evening you may need a long- sleeve skirt and a light coat for the cooler weather.
September falls in peak travel season. The weather is clean and clear, so it is the best time to enjoy the autumn scenery.
