The Iberá in November

November is spring in the wetlands. This is what happens in the Iberá this month and what to know before you travel.

Late spring. Temperature and humidity rise, and the landscape fills with flowers and chicks.

Season

The high season of the Iberá is from June to October. Winter (June to August) is a very good time: cool, dry weather, no mosquitoes and caimans sunning on the banks. 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. Rain is concentrated between autumn and spring (March, April and October are among the wettest months) and winter is the driest part of the year, with August the driest month.

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.
