When to go, and when not to
The months with the highest visit scores are January, March, October, and November. Daytime highs in these months range from about 24.7C to 26.0C, with sunshine averaging between 10.6 and 11.7 hours a day, making them the most consistently favorable stretch of the year for outdoor activity.
These same months overlap with the peak season, which also includes July and August, so travelers should expect higher demand during them. January and November bring more rainfall, at 75mm and 78mm respectively, and February, just outside the top-scoring months, is the wettest of the year at 136mm, so travelers sensitive to rain may want to weigh that against the sunnier days these months also offer.
