**Recent forecast updates from meteorological models position 17°C as the leading outcome for Sao Paulo’s September 13 maximum, with traders assigning it a 57% implied probability.** Persistent cloud cover, light rain, and a cooler-than-average air mass—driven by southeasterly flow and high humidity—have suppressed daytime heating below the month’s typical 23–24°C average. Hourly observations and ensemble guidance show temperatures peaking near 16–17°C during afternoon hours, consistent with the market’s secondary probabilities for 16°C (21.5%) and 18°C (18.5%). NOAA and regional analyses highlight the influence of transient frontal activity that has kept conditions overcast, limiting solar insolation. Updated model runs through the morning of the 13th show little deviation from this range, with resolution expected once official station data confirm the daily high.

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.
