Highest temperature in Tokyo on July 28?

Platform comparison

Market context

Tokyo's highest temperature on 28 July 2026 will be recorded at Haneda Airport Station and resolved via Weather Underground historical data. July is peak summer in Tokyo, with typical daily highs ranging from 32–35°C, though heat waves can push readings above 37°C. The settlement window closes at midday UTC on 28 July, meaning traders must assess forecasts available up to that point; any temperature recorded after midnight local time on 28 July counts toward resolution.

Historical precedent shows Tokyo experiences significant year-to-year variance in summer heat. The Japan Meteorological Agency recorded 41.1°C in central Tokyo on 16 July 2023, the highest since records began in 1875. However, Haneda Airport, situated on reclaimed land near Tokyo Bay, typically records temperatures 1–2°C lower than central districts due to maritime influence. The 0% crowd probability likely reflects uncertainty about which specific temperature band will be hit rather than doubt that a reading will occur; all outcome ranges should theoretically carry non-zero probability given the deterministic nature of the underlying event.

Traders should monitor Japan Meteorological Agency forecasts released 7–10 days before 28 July, which provide the most reliable guidance for seasonal heat patterns. El Niño or La Niña conditions in the preceding months influence Pacific typhoon activity and upper-air circulation, potentially moderating or intensifying summer heat. Recent years have shown increased frequency of extreme heat events across East Asia; the Japan Meteorological Agency publishes weekly heat-stress advisories that serve as leading indicators for temperature extremes.

FAQ

How are winnings taxed?

Tax treatment varies by jurisdiction. In most countries, prediction market gains are treated as ordinary income or capital gains. We cannot provide tax advice — consult a tax professional for your specific situation.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Polymarket Tax UK stores an email address and wallet addresses rather than a legal name. Over $1,500 lifetime volume triggers KYC, after which identity is no longer anonymous.

What happens during a tax audit?

You're responsible for documenting your trades. Polymarket Tax UK exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.

Are prediction markets gambling?

Legally unclear in most jurisdictions. Some interpretations classify them as wagering (gambling regulation applies), others as derivatives (financial regulation applies). There's no global precedent specifically for on-chain prediction markets.

Is there a withdrawal cap?

No platform-side cap. You can withdraw any amount provided KYC is complete. SEPA bank withdrawals over €15,000 trigger additional anti-money-laundering checks (statutory obligation for all platforms).
