Highest temperature in Madrid on July 31?

Platform comparison

Market context

Madrid’s **highest temperature** on 31 July is the event that matters here, and the relevant reading is the day’s peak at Adolfo Suárez Madrid-Barajas Airport rather than a citywide average. Public forecasts for Madrid on 31 July point to a very hot afternoon: AccuWeather shows highs around the mid-30s to low-30s Celsius depending on the station view, while Infobae reports a forecast maximum of **38°C** for the city with **0%** rain.[1][2][4][5]

The current **0% YES** probability is best read against Madrid’s late-July climate, which routinely produces high-30s readings and occasional low-40s extremes. WeatherSpark’s July climate data shows typical daily highs around **31–33°C**, with rare exceedances above **37°C**[7][9], while Madrid’s historical extremes have reached **40.7°C** on multiple summer dates.[10][15] That means the market is not asking whether it will be warm, but whether the airport station’s maximum lands in the specific range implied by the contract; a single hot burst near mid-afternoon can be enough to move the outcome, so a zero-implied price is largely a statement about distribution rather than certainty.

For traders, the main catalysts are the day-of forecast updates, any heat advisories, and the timing of the airport station’s observed peak before the settlement window closes at **12:00 UTC**. Local coverage on 31 July already points to strong heat and dry conditions, with wind and cloud cover limited.[4] On the regulatory and access side, a market like this sits in a grey zone for many users: German **GlüStV** rules can restrict participation where a platform is treated as gambling; the **US CFTC** can assert reach over event-contract activity involving US persons; and “**no-KYC up to $1,500**” generally means small-volume access may be available without full identity verification, but only until cumulative activity crosses that threshold and subject to the platform’s own geofencing and compliance checks.

FAQ

Is Polymarket legal in my country?

Polymarket is geo-blocked in the US/UK/EU. Actual usage via the Polymarket interface is not possible there. The legal status itself varies — many countries treat prediction markets as a gray area. Is Polymarket Legal in Canada has a different geo footprint.

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. Is Polymarket Legal in Canada 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.

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).
