The first day of Lollapalooza 2026 in São Paulo is expected to have unstable weather with a chance of rain and a drop in temperature throughout the day.
The Lollapalooza festival kicks off on Friday, March 20, 2026, in Interlagos, São Paulo, with weather forecasts predicting unstable conditions. Meteorological reports from Climatempo suggest that attendees should brace for potential rain in the afternoon, which could affect the outdoor performances, alongside a noticeable drop in temperature over the course of the day. Initially, the day will feel warm, characteristic of the lingering summer season before the official start of autumn a few hours later.
As the festival prepares to open its gates at 11 a.m., the temperature will be around 26ºC, but it is anticipated to decrease to 23ºC and even further to 19ºC by nightfall. This change in temperature may create a chilly environment for festival-goers, especially during nighttime performances. Consequently, attendees are advised to dress accordingly to counter the cool evening temperatures while still being prepared for possible showers.
In the wider São Paulo area, temperatures might soar higher, with some regions reaching up to 27ºC. Overall, the weather on the festival's opening day presents a mixed bag of conditions that could impact the schedule and experiences of those attending. Therefore, keeping an eye on updates and weather forecasts is crucial for a successful festival experience this weekend.
