When to go, and when not to
The strongest months to visit by visit score are June, July, August, and September, all landing in the peak season window. July brings the warmest average high at 26.8C along with the most sunshine at 12.8 hours a day, while September combines a high visit score with lower rainfall at just 43mm and a high of 22.2C.
The trade-off for visiting in peak season is that these same warm, sunny months draw the most visitors, and summer months from April through September also bring frequent thunderstorms. Rainfall is highest in April at 113mm, and travelers preferring quieter, cheaper conditions can look to the off season months of January, March, and December instead, though these bring colder temperatures such as January's high of -0.0C and low of -5.5C.
