Paraguay carries the UNESCO Jesuit Missions of Trinidad and Jesús' red-stone ruins, the Chaco's tannin-coloured rivers and Mennonite colonies, and Asunción's faded grandeur on the Paraguay River.
Cool dry winter the best window for Chaco wildlife and Jesuit Missions exploration, with Asunción's mild temperatures pleasant for Pantheon walking.
Spring shoulder before summer heat, lapacho trees in flower across the country, and Encarnación Carnival the country's biggest celebration in February aside.
Hits 38°C in Asunción with humidity, Chaco unbearable by midday, but Encarnación Carnival in late February the country's main draw.
End of summer with Asunción cooling, lapacho still in bloom in some valleys, and the Paraguay River at peak level for tourist boat trips.
