SeasonMap

Insect season, month by month around the world

Flies, midges, mosquitoes or sandflies at their worst; nets and repellent weather.

This is a warning page, not a recommendation. Insect season covers 48 destinations on SeasonMap; the months below are the ones in which the risk window is open — most weeks in them pass quietly, and the score beside each place is still the ordinary climate score, hazard and all.
