Hot, hotter, hottest in Pua

Traveling in Thailand

It is begin April and since a few weeks it is hot, very hot. With morning temperatures of 22℃ and afternoon 38-40℃. So in the afternoon I retire to our bedroom, the only room in house with air-conditioning. But animals living outside do not have this option, so they are looking for other places to cool down. And what else as a muddy pool of water would be better for a water buffalo?
