Highest temperature in Kuala Lumpur on August 16?

Platform comparison

Market context

On 16 August 2026, the highest temperature recorded at Kuala Lumpur International Airport will fall within one of several defined ranges, measured in degrees Celsius and sourced from Weather Underground's Daily Observations table. The market currently prices at 0% YES across all temperature brackets, reflecting either incomplete liquidity or trader uncertainty about which range will resolve. Polymarket's conditional token structure on Polygon means positions settle in USDC against whichever bracket captures the actual high, with resolution tied explicitly to the Daily Observations data rather than summary figures.

Kuala Lumpur's August climate is remarkably consistent. Historical records show daily highs clustering between 32–34°C during the monsoon season, with extremes rarely exceeding 35°C even during the hottest afternoons. The city's equatorial location and maritime influence create a narrow band of variation; traders should reference the past five years of August data from the same airport station to calibrate expectations. August 2023 and 2024 both recorded highs in the 33–34°C range on comparable dates, establishing a baseline against which outlier scenarios should be weighted.

The key variable is whether tropical convection or unusual atmospheric conditions might push temperatures above the historical norm. Malaysia's Meteorological Department typically issues monsoon forecasts in July, and any El Niño or La Niña signals could influence August conditions. Traders should monitor weather advisories released in early August 2026 and track real-time airport observations as the settlement date approaches, since afternoon readings can shift based on cloud cover and wind patterns in the 24 hours preceding the measurement window.
