Iguazu Falls: water flow this week

The flow of the Iguazu River, measured in cubic meters per second (m³/s – the volume of water passing a point each second), is 4,130 m³/s, with a level of 246 cm. In the last seven days, the flow ranged between 4,130 and 7,367 m³/s, indicating that the power of the falls is decreasing – the trend is a 12.7% drop in about a week.

For those planning to visit Iguazu Falls, located on the border between Brazil and Argentina, the flow directly influences the strength and volume of the waterfalls: the higher the flow, the more intense and full the water curtains. When the flow is around 4,130 m³/s, the falls are still impressive but less voluminous than at peaks of 7,000 m³/s, which can make the experience more comfortable for those who prefer fewer splashes and shorter lines at the viewpoints.

The flow reduction usually occurs in the dry season, when rainfall in the Iguazu basin is lower. Even so, the Falls remain open and safe for visitors, with the same operating hours and attractions such as the Macuco Safari boat ride and the Garganta Trail.

What this means for you: With the flow at 4,130 m³/s, expect still beautiful falls, but less voluminous and fewer splashes on boat tours; it’s a good time for those who want to avoid crowds and don’t mind less maximum water power. Bring a light raincoat or poncho, but you may need less protection against heavy water.
