May, June, and October are the strongest months for a visit, combining milder temperatures with more sunshine hours than the winter or peak summer months. May and June see highs in the low-to-high 20s Celsius with 8.8 and 8.2 hours of sunshine per day respectively, while October cools slightly to a high near 24 degrees Celsius with 7.9 hours of sunshine, all offering a more comfortable balance than the extremes of the year.
The trade-off is that May, June, and October are also the peak season, meaning more visitors and likely higher demand on lodging. June is also the wettest month at 324mm of rain, and July and August bring the most intense heat, with highs of 33.1 and 34.4 degrees Celsius, conditions reflected in their lower visit scores. Travelers who prioritize lower costs and fewer crowds over ideal weather may prefer the off-season months of February, July, and August instead.
