Highest temperature in Taipei on August 9?

Platform comparison

Market context

Taipei’s outcome will be set by the warmest **hourly observation** at Taipei Songshan Airport in the Weather Underground **Daily Observations** table, so the relevant question is not the displayed day summary but the peak reading logged before the settlement cut-off. Current forecast pages point to a hot, wet day with highs around 30–31°C and heavy rain, which still leaves room for an upper-end reading if sunshine breaks through between showers.[3][11][15]

The 6% crowd price implies the market is treating a very high outcome as unlikely relative to the usual August climatology, where Taipei often sits in the low- to mid-30s but monsoon rain can cap temperatures through cloud cover and storm activity.[4][13][14] A recent resolved temperature market for Taipei in early August settled on 37°C after the station hit that level, showing that extreme readings are possible when heat builds under favourable conditions.[17] For comparison, Taipei has also recently logged a May record of 38.3°C at the city weather station, reinforcing that the city can occasionally overshoot seasonal norms.[18]

For traders, the key catalysts are the morning-to-afternoon observation path at Songshan Airport, any sudden convective rain, and whether the day turns sunnier than current guidance suggests. Weather services currently show high rain chances and only modest highs, so the main risk to a low outcome is a brief hot spell before precipitation, while the main risk to a higher outcome is persistent cloud and rain suppression.[3][11][15] On access, German GlüStV rules can limit or prohibit participation from Germany depending on platform licensing and classification, while US CFTC reach mainly matters if a venue is deemed to offer a derivatives-like product to US persons; “no-KYC up to $1,500” generally means small balances may be usable with lighter identity checks, but it does not remove geo-blocking, sanctions screening, or exchange-level compliance limits for this specific market.
