Highest temperature in San Francisco on July 12?

Platform comparison

Market context

San Francisco’s highest temperature on 12 July 2026 will be recorded at the San Francisco International Airport Station, with resolution based on Wunderground’s daily high for that date. The city’s coastal geography typically traps a cool, moist boundary layer, capping daytime highs near 70–75°F, making extreme heat unlikely despite broader Western heatwaves.

Historical July data shows average highs around 72.3°F, with long-term averages near 20°C (68°F), and few days exceeding 75°F[2][8]. A recent heat dome over the northern US raised temperatures in Billings to 107°F, but Pacific cold fronts are expected to limit similar impacts in San Francisco[6][9]. The current market’s 0% YES probability for extreme heat aligns with this climatic pattern, though the frontrunner outcome is 72–73°F at 30%[1].

Traders should monitor the National Weather Service’s heat dome forecasts and Pacific front movement, as these directly influence whether San Francisco breaks its typical July ceiling[3]. Regulatory access hinges on German GlüStV rules, US CFTC reach, and the platform’s ‘no-KYC up to $1,500’ threshold, which permits smaller retail participation without identity verification. This structure expands accessibility while remaining within current compliance frameworks for prediction markets in Germany and the US.

FAQ

Do I need to KYC for Polymarket Germany Legal?

Not for lifetime trading volume under $1,500. Above that threshold, a quick KYC flow kicks in — ID, selfie, approximately 5-10 minutes. The threshold matches FATF travel standards for unregulated crypto platforms.

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 Germany Legal 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 Germany Legal 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.
