Highest temperature in Manila on August 17?

Platform comparison

Market context

Manila's highest temperature on 17 August 2026 will be measured at Ninoy Aquino International Airport using Weather Underground's Daily Observations table, with resolution occurring at midday UTC on that date. The market currently shows zero probability assigned to any temperature range, suggesting either incomplete pricing or uncertainty about which bracket will ultimately contain the day's peak reading.

August represents Manila's peak monsoon season, with historical daily highs typically ranging between 28–32°C at the airport station. The 0% crowd probability across all ranges is unusual given that some outcome must occur; comparable weather markets on prediction platforms typically distribute probability across multiple temperature bands rather than concentrating entirely on zero. This suggests either sparse liquidity in the market or traders awaiting clearer atmospheric forecasts before committing capital. Historical data from previous August 17ths at the same station would provide the most relevant baseline for expected ranges, though inter-annual variation in monsoon intensity can produce meaningful deviations.

Traders should monitor tropical cyclone activity in the Western Pacific during early-to-mid August 2026, as storm systems can substantially depress daytime temperatures through cloud cover and precipitation. Weather Underground's forecast updates and the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) advisories will be critical signals. The specific resolution methodology—using Daily Observations rather than the Day High & Low summary—means traders must verify which measurement protocol Weather Underground applies on the settlement date, as discrepancies between sections have historically occurred.

UK Frequently Asked Questions

How accurate are political prediction markets?

Historically more accurate than polls. Polymarket's Brier score on US 2024 elections was ~0.11 — better than 538 (~0.14) and every mainstream poll. Markets aggregate information with real skin in the game.

Which platform has the deepest political liquidity?

Polymarket — by far. US 2024 presidential volume was ~$3.5B vs Kalshi (~$200M) and Betfair (~$120M). Where Polymarket is geo-blocked, brokers like Trump Prediction route into the same order book at 0% fees.

How fast do political markets react to news?

High-liquidity markets move within seconds to minutes. A Trump tweet on the economy can shift the "Trump 2024" market 2-5 points before mainstream media has written anything.

Why do Polymarket and Kalshi differ on elections?

Kalshi must follow CFTC compliance — strict definitions, clear resolution sources, US citizens only with KYC. Polymarket operates globally without CFTC oversight — deeper liquidity, but also higher regulatory risk.

Are UK election prediction markets available from the UK?

Yes. Betfair Exchange and Smarkets offer UKGC-regulated UK election markets (seat counts, party share, constituency results). Polymarket also lists UK election contracts with deeper global liquidity. Betfair winnings are typically tax-free for UK individuals; Polymarket profits are subject to HMRC CGT.
