When to go, and when not to
July and September stand out as the best months to visit, based on the highest visit scores of the year. July offers the warmest average high at 23.4C and the most sunshine at 13.6 hours per day, while September brings a milder average high of 19.2C, a low around 11.0C, and noticeably less rain at 51mm compared to the summer months.
The trade-off is that July, August, and September make up the peak season, so travelers choosing these months should expect the busiest conditions of the year. July is also the wettest month on average with 97mm of rain and the hottest with a high of 23.4C, so travelers sensitive to heat or rain might prefer the somewhat cooler and drier conditions of September while still catching strong sunshine hours.
