Methodology
The movement forecast in the Tourism Intelligence Panel is a planning-support estimate: for the visitor and for the destination. This page explains, transparently, which signals feed the calculation, how often it runs and what its limits are today.
The current estimate is a transparent calculation from day, hour, holiday and weather: it combines public, verifiable signals with no black box. Each signal adds or subtracts points, and the total sets the forecast level (low, moderate, high, very high).
July (Brazilian school holidays + Argentine/Paraguayan winter break) and the summer (December-February) raise movement even on weekdays; April-June is the quietest stretch. Calibrated against the three countries' school calendars, the Iguaçu National Park's official visitation and ANAC's passenger series.
Weekends and Fridays raise movement at attractions and border crossings; weekdays tend to be quieter outside the high season.
A public holiday in any one, Brazil, Argentina or Paraguay, increases flow at the border. We cross-reference the official BR, AR and PY calendars.
A forecast of rain or storms reduces demand for open-air attractions (the Falls, the Three Frontiers Landmark).
The calculation is refreshed every 10 minutes with live weather, and the three countries' holiday calendars are revalidated daily. The exchange and weather data feeding the panel are collected three times a day and stored as a historical series.
The next steps take the estimate to a validated predictive model, incorporating new signals and, above all, observed visitation data to measure accuracy.
Sharp moves in the real, guaraní and peso shift the shopping flow in Ciudad del Este and Puerto Iguazú.
Festivals, concerts and conferences on the destination's agenda anticipate occupancy peaks.
Once we integrate real visitor counts, the forecast moves from an estimate to a validated model, with a measured accuracy rate.
Honest disclaimer
The forecast is a planning-support estimate, not a guarantee. Real conditions vary with factors we don't capture (attraction operations, last-minute events, local weather). Use it to pick the best time and skip the queues: and always check each attraction's official sources before you go.
