A cold front and associated rain system are driving the strong market consensus around a maximum of 24°C or below for São Paulo on September 22. Multiple forecast models show an overcast day with an 80% or higher chance of thunderstorms, southerly winds shifting in cooler maritime air, and daytime highs projected between 20–24°C—well below the seasonal average near 23°C. Recent model runs have converged on this cooler, wetter pattern after warmer conditions earlier in the week, reducing upside risk for temperatures above 25°C. Official monitoring from agencies like INMET will confirm the daily maximum by evening on the 22nd, with traders closely watching any last-minute forecast shifts in steering flow or rainfall timing that could alter the peak reading.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=sbgr
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
