We have never had more taifū (台風, typhoon)-related news than we have had this year. Japan has had at least 28 typhoons so far in 2013 and the number is likely to surpass 30 — the first time this will have happened in 19 years.

A remarkable point is that this year there have been many aki-taifū (秋台風, fall typhoon), which has something to do with September and October being unusually hot. According to kishōchō (気象庁, the Japan Meteorological Agency), the number of typhoons up till August was 15, which is heinen nami (平年並み, close to the level in an average year). But September saw eight typhoons, well above the 4.8 average.

There needs to be only two typhoons in the remaining two months of the year to reach 30, and with the average for November and December being 3.5, that seems sure to happen.
