When to go, and when not to
April, May, and October stand out as the strongest months to visit based on long-term climate averages. April brings a high around 22.7C with 7.7 hours of sunshine a day, May climbs to a high near 26.5C with 8.4 hours of sunshine, and October cools back down to a high of about 23.8C with 6.8 hours of sunshine, all with comparatively moderate rainfall for the year.
These same months make up the peak season, so travelers should expect busier conditions at popular sites. The trade-off for cooler, drier weather in the off-season months of February, July, and August is real: July and August bring highs near 33C and heavy rain in June reaches 280mm, making midsummer the hottest and one of the wettest stretches of the year, while February remains cooler with less sunshine.
