Alger og rødt tidevann, måned for måned rundt om i verden

Oppblomstringer som stenger strender og tømmer vannet for fisk i noen uker; ikke den karibiske tangen.

Dette er en advarselsside, ikke en anbefaling. Alger og rødt tidevann omfatter 10 reisemål på SeasonMap; månedene under er de der risikovinduet er åpent — de fleste ukene i dem går stille for seg, og scoren ved siden av hvert sted er fortsatt den vanlige klimascoren, fare og alt.
