Alghe e marea rossa, mese per mese nel mondo
Fioriture che chiudono le spiagge e svuotano l'acqua di pesci per qualche settimana; non l'alga dei Caraibi.
Questa è una pagina di avvertenza, non un consiglio. Alghe e marea rossa riguarda 10 destinazioni su SeasonMap; i mesi qui sotto sono quelli in cui la finestra di rischio è aperta. La maggior parte delle settimane passa tranquilla, e il punteggio accanto a ogni luogo resta il normale punteggio climatico, rischi compresi.
