The months with the highest visit scores in the climate data are March, October, November, and December. These months combine cooler or more moderate temperatures with comparatively low rainfall, particularly December, which has the lowest monthly rainfall of the year alongside cooler highs and lows.
The trade-off comes in the peak season months of March, August, October, November, and December, when accommodation and tours see more demand even though the weather is favorable. The wettest and hottest conditions occur from May through September, with June, July, and September recording the heaviest rainfall of the year, making outdoor sightseeing less comfortable even though these months fall in the cheaper off-season window.
