About this market
This market will resolve to the temperature range that contains the highest temperature reported at King Abdulaziz International Airport (OEJN) on 23 Oct '26. The qualifying value is the highest temperature reported in the hourly temperature remark of any routine (METAR) observation for King Abdulaziz International Airport (OEJN) on that date, in tenths of a degree Celsius as reported. A report whose line begins with SPECI is a special observation and does not count. Every other report is routine, including one issued off the nominal hour and one that carries no METAR or SPECI label. For How to Read the METAR Report, see: https://polymarket-upload.s3.us-east-2.amazonaws.com/market_products/Weather/How+to+Read+the+METAR+Report.pdf The hourly temperature remark is the group beginning with the letter T followed by exactly eight digits. After the T, one digit for sign (0 positive, 1 negative) and three for tenths of a degree Celsius give the temperature; the following four are the dew point and are not used. T01390133 is 13.9°C; T10171022 is −1.7°C. If a routine observation does not carry the hourly temperature remark, the temperature group in the body of that observation governs for that observation, in whole degrees Celsius as reported. It appears as temperature and dew point separated by a slash, with M marking a negative value: 18/12 is 18°C; M11/M17 is −11°C. An observation that reports no temperature in either place is disregarded. Each market in this event states its range in whole degrees Celsius. The qualifying value is rounded to the nearest whole degree, with a value ending in exactly half rounded up to the next higher whole degree, and that whole Celsius value determines which range contains it. For example, 13.9°C counts as 14°C; 17.4°C counts as 17°C; 16.5°C counts as 17°C; −1.7°C counts as −2°C; −8.5°C counts as −8°C. An observation counts if its time stamp, converted to the station's local time (including any daylight-saving shift in effect), falls on th
