April, May, and October stand out as the strongest months to visit based on long-term visit scoring, and the weather data explains why: April and May bring highs in the low-to-upper 20s Celsius with moderate rainfall, while October offers a high near 24.7C with much lower rainfall than the summer months. This combination of warm days and comparatively manageable precipitation makes these three months the most pleasant window for outdoor sightseeing.
The trade-off is that April, May, and October are also the peak season, so travelers chasing the best weather will likely encounter more visitors. Those same months sit between a wetter, hotter stretch, June sees the heaviest rain at 367mm, while July and August bring the highest temperatures of the year, with highs of 34.1C and 35.3C respectively, which is part of why many travelers avoid the deep summer despite its long sunshine hours.
