When to go, and when not to
January, February, November, and December stand out as the best months to visit, based on the highest visit scores of the year. These months combine warm daytime highs between 26.1C and 29.8C, cooler nights as low as 14.1C, minimal rainfall of 4 to 34mm, and strong sunshine averaging around 9.6 to 10.2 hours a day.
The trade-off is that some of these same months, particularly January, February, November, and December, along with July and August, are also peak season, meaning higher demand alongside good weather in the cooler months. The middle of the year brings the heaviest rain and heat: April is the hottest month with highs of 34.1C, while May, June, July, and August bring heavy monsoon rainfall, peaking at 594mm in August, making that stretch the wettest and least comfortable time to visit despite lower costs.
