When to go, and when not to
The best-rated months to visit are January, February, March, and November, when daytime highs range from about 25C to nearly 32C and rainfall stays low, often close to zero. Sunshine hours during these months run from roughly 11.6 to 13.7 hours a day, giving travelers long, bright days for sightseeing outdoors.
The trade-off is that January through March and November fall within the peak season, alongside July, so popular sites and transportation may be busier. Travelers seeking lower prices and fewer crowds can look to the off-season months of May, June, and August, though June and August bring the heaviest rainfall of the year, at 131mm and 123mm respectively, and shorter daylight with sunshine hours dropping to around 5.9 to 7.5 hours a day.
