Highest temperature in Taipei on August 8?

Platform comparison

Market context

Polymarket is currently pricing this Taipei temperature contract at **0% YES**, which on-chain means traders are assigning no meaningful probability that the highest reading in Weather Underground’s **Daily Observations** table for Taipei Songshan Airport on 8 August will land in the winning Celsius band. Because the market settles in **USDC** on **Polygon** via conditional tokens, the practical question is not whether Taipei will be warm, but whether the station’s recorded peak clears the contract’s resolution bucket before the midday UTC settlement window closes. AccuWeather is showing Taipei with **heavy rain and thunderstorms** on 8 August, with a forecast high around **90°F/32°C**, while Weather Underground’s current observations already show **88°F/79°F** in Taipei as of the morning local time, indicating a warm but not extreme start to the day.[2][7]

For market context, Taipei in August is normally hot and humid, with typical daily highs in the high-20s to low-30s Celsius and frequent rain, so a low-priced “YES” outcome usually reflects the view that the day’s maximum may stay within the ordinary summer band rather than reach an outlier spike.[4][12][14] Forecasts from several weather services point to rain, cloud cover and storm risk on 8 August, which tends to cap inland heating and reduce the chance of a late-afternoon extreme.[2][3][9][10] The key comparables are therefore not heatwave days, but ordinary monsoon-season days where the station briefly touches the low-30s Celsius before rain or cloud suppresses further gains.[10][18]

A trader should watch the **Weather Underground Daily Observations** page for Taipei Songshan Airport, because that is the settlement source and it overrides the site’s summary high/low if the two disagree.[7] The main catalysts are any short-lived clear spells, convective bursts, or timing shifts in rain bands that could let the temperature print a higher afternoon maximum before cooling begins, especially given the strong precipitation signals from the forecast sources.[2][3][9] Since the market resolves from the observed station maximum rather than a headline forecast, the most relevant live inputs are the hourly station readings and whether the day’s peak is logged before 12:00 UTC.
