This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section. This market will resolve to the temperature range that contains the highest temperature recorded at the Sao Paulo-Guarulhos International Airport Station in degrees Celsius on 14 Aug '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Sao Paulo-Guarulhos International Airport Station, available here: https://www.wunderground.com/history/daily/br/guarulhos/SBGR. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C. This market can not resolve until the first data point for the following date has been published on the resolution source. 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.
Current meteorological forecasts from models such as ECMWF and GFS position 24–26°C as the most probable maximum temperature range for São Paulo on August 14, aligning with the market's leading implied probabilities. In the Southern Hemisphere winter, typical high-pressure systems and reduced solar insolation limit daytime heating, with recent ensemble runs showing light southeasterly winds and scattered cloud cover that moderate peaks near the seasonal average of 23–25°C. Official monitoring from INMET and short-range updates confirm no significant warm advection or clear-sky anomalies are expected to push values higher, while cooler boundary-layer conditions keep lower outcomes less likely. Traders are weighting these consensus projections heavily ahead of final observational data on the 14th.
