Highest temperature in Manila on June 30?

Platform comparison

Market context

Manila’s highest temperature on 30 June 2026 is the real-world event determining this market’s outcome, with current crowd-implied probability at 0% for any temperature above the baseline range. Historical data shows daytime highs in Manila during June typically reach 32°C, accompanied by very high heat and humidity, while overnight lows fall to 24°C[2]. Long-term averages confirm daily high temperatures range between 26°C and 32°C, with April being the hottest month and the wet season beginning in June[3]. Recent forecasts for late June 2026 indicate temperatures may climb to 34°C, suggesting the 0% probability for higher ranges may be premature given typical seasonal volatility[9].

Traders should monitor announcements from the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa), which recently forecast dangerous heat indices reaching 44°C in Metro Manila earlier in May[4]. The market leans on the catalyst of tropical storm activity, as an average of 1.2 days in June in Manila are affected by tropical storms, potentially altering temperature patterns[2]. A low-pressure area (LPA) currently posited to bring heavy rain to Southern Luzon and Visayas may also impact Manila’s weather on 30 June, according to a 30 June 2026 forecast[8]. These dependencies, combined with scheduled climate declarations, form the core variables traders must watch as the settlement window approaches.

FAQ

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.

What resolution source is used for elections?

Polymarket defines the source per contract — usually Associated Press (AP Race Call), Reuters or the official electoral commission. The source is stated in contract details before the market opens.

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 Election Predictions UK route into the same order book at 0% fees.

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.

Which political events have the biggest volume?

US Presidential election, party nominations (DNC/RNC), Senate majorities, individual state outcomes (Pennsylvania, Michigan, Wisconsin), and major European elections. Peak markets reach $50-500M per event.
