Sezon powodzi, miesiąc po miesiącu na całym świecie

Rzeka wchodzi w ulice niemal co roku.

To strona ostrzegawcza, a nie rekomendacja. Sezon powodzi obejmuje w SeasonMap 112 kierunków; miesiące poniżej to te, w których okno ryzyka jest otwarte — większość tygodni mija spokojnie, a wynik obok każdego miejsca to wciąż zwykły wynik klimatyczny, razem z zagrożeniem.

Kiedy trwa

Liczba kierunków, w których sezon powodzi trwa w danym miesiącu. Okna co roku nieco się przesuwają.
