Climate Like most of Gujarat, Porbandar has a
hot semi-arid climate (
Köppen BSh) with three distinct seasons: the “cool” from October to March, the “hot” in April, May and early June, and the
monsoonal “wet” from mid-June to September. Almost no rain falls outside the monsoon season, except for a very few late-season
tropical cyclones. The most powerful one occurred on 22 October 1975 and produced a storm surge of . During the monsoon season, rainfall is exceedingly erratic: Annual rainfall has been as low as in 1918 and in 1939, but as high as in 1983—when a cyclone caused over to fall over four days—and in 1878. With a
coefficient of variation exceeding fifty percent and an expectation of only 41 percent of mean annual rainfall in the driest year in ten, the Porbandar region is among the most variable in the world—comparable to northern Australia, the Brazilian
sertão and the Kiribatese
Line Islands. An illustration of Porbandar's extremely variable rainfall can be seen from 1899 to 1905 when seven successive years produced annual falls of: • in 1899 • in 1900 • in 1901 • in 1902 • in 1903 • in 1904 and • in 1905 Porbandar, owing to its coastal location, is the least hot of all major
cities in Gujarat: Average high temperatures do not reach in any month. {{cite web == Demographics ==
