When to go, and when not to
June through September stand out as the best months to visit, each carrying the highest visit scores of the year. June brings an average high of 26.8C with 12.7 hours of sunshine a day, while July and August push warmer still, with July averaging 28.8C and 13.1 hours of sunshine and August reaching 29.6C. September stays warm at 25.4C with a bit less sunshine at 10.3 hours a day.
The trade-off is that these same months form the peak season, so travelers should expect the busiest conditions of the year. September is also the wettest month on record here, averaging 123mm of rain, notably higher than the other summer months, while August's 29.6C average high is the hottest of the year, so travelers sensitive to heat or rain may want to weigh those factors against the appeal of long sunshine hours.
