Japan Weather for Sailors

The north is cold, while the south is in the monsoon belt. Most of the country is in a temperate four seasonal zone. Summer sees SE winds and a rainy season in June and July. Typhoons are most frequent mid-July to October, but can occur at any time; five to ten days' warning are usually given. Fog may be a problem at times so having radar is essential. Although typhoons are a constant threat, weather forecasts and faxes are good and reliable, and almost every port has a typhoon shelter.
