When to go, and when not to
The strongest months for a visit are January, February, March, and December, which carry the highest visit scores in the climate record. These months combine cooler high temperatures, ranging from about 23.0C in January to 26.0C in March, with comparatively little rain, such as 14mm in January and 16mm in December, and solid sunshine of 8.4 to 10.3 hours a day.
The trade-off comes in the warmer months, when peak season overlaps with some of the wettest and hottest conditions: July reaches a high of 31.7C alongside 493mm of rain, the heaviest monthly total of the year. May, June, and July form the off-season with lower visit scores, so travelers gain lower demand and likely lower prices but face higher rainfall, more heat, and the start of typhoon season, which runs from May through November.
