Bagan

Nyaung-U has a hot semi-arid climate (Köppen BSh) due to the rain shadow of the Arakan Mountains. Afternoon temperatures are hot to sweltering throughout the year, although mornings at the height of the dry season between December and February are comfortable. Rainfall occurs between May and early November, but totals only about one-eighth that of the extreme tropical monsoon climate of Sittwe at the same latitude on the Bay of Bengal. Unlike most monsoonal semi-arid climates, the rainy season is relatively long at around five to six months, while variability and extreme monthly and daily rainfalls are much lower than usual with this type of climate. The 8.10 inches or 205.7 millimetres rainfall of 19 October 2011 was the record breaking one for past 47 years. The previous record was 5.67 inches or 144.0 millimetres on 9 October 1989.
