Buenos Aires experiences autumn weather in mid-April with typical daily high temperatures ranging from 18 to 25 degrees Celsius. The current market prediction focuses on a very specific outcome: whether the highest temperature on April 18 will be exactly 21 degrees Celsius. The 0% YES odds indicate that traders currently assess this precise outcome as highly unlikely. This reflects the challenge of predicting an exact single-degree temperature in a city's daily high, as official weather data typically shows variation and the atmosphere rarely aligns with such precise thresholds. Buenos Aires' weather during this season is influenced by cold fronts from the south and warmer Atlantic systems, creating variability in daily highs. The market has seen limited trading volume at $1,726 over 24 hours, suggesting low confidence in any specific single-degree outcome. Resolution will depend on official Buenos Aires meteorological station data, which records the highest temperature reached during the calendar day. The odds trajectory reflects the inherent difficulty in predicting exact temperature outcomes in real-world weather systems.
