May weather forecast
Easter Island, Chile

Come May, the decisions of the weather gods, swaying between summer's warmth and winter's cool embrace, become more evident. The temperature gradient between day and night widens, with cool nights becoming a norm. A surge in precipitation levels to 153mm (6.02") often results in overcast skies, which, in turn, restrict daylight hours to an average of 10.8 hours. However, the UV index dips to 5, making it much safer to venture outdoors. Despite the increased rainfall, the creation of multiple rainbows across the sky add to the island's charming diversity.
