Røgsæson, måned for måned rundt om i verden

Marker eller skove der brænder; luften, ikke vejret, er problemet.

Dette er en advarselsside, ikke en anbefaling. Røgsæson dækker 115 rejsemål på SeasonMap; månederne nedenfor er dem, hvor risikovinduet er åbent — de fleste uger i dem går stille, og scoren ved siden af hvert sted er stadig den almindelige klimascore, risiko og det hele.
