End of summer, start of autumn. The heat eases off, rain is still around, and it is the last month of low season before the best time of year begins.
Season
The high season of the Iberá is from June to October. Winter (June to August) is the best time: low water, concentrated wildlife, cool weather and no mosquitoes. Long weekends and July are the peaks of occupancy: book in advance. The low season (January to March) has extreme heat but also very active wildlife at dawn.
Weather
The Iberá has a humid subtropical climate. Average temperature in January: 27°C, in July: 16°C. Absolute highs exceed 40°C in summer. Frosts are possible between June and August. It rains all year round, around 1,400 mm annually: the wettest months are March and April (over 160 mm each) and winter is the dry season, with July and August around 55 mm, a third of what falls in March.
Mosquitoes
Mosquitoes are most active in summer (December to March) and at dusk. With proper repellent and lightweight long clothing they are not a real problem. In the cold months (May to August) there are practically no mosquitoes. The lodgings in the Iberá always have mosquito nets.
