Highest temperature in Miami on August 13?

Platform comparison

Market context

On 13 August 2026, Miami International Airport will record its highest temperature for that date. The resolution hinges on the Daily Observations table from Weather Underground rather than the Day High & Low summary section—a distinction that matters when intraday peaks diverge from official closing figures. The 0% crowd probability suggests traders currently expect no extreme heat spike, though Miami's August climate regularly produces temperatures in the low-to-mid 90s Fahrenheit.

Historical August temperatures at Miami International Airport show a median high around 91–92°F, with the record for any August day reaching 98°F. The current zero probability reflects baseline expectations; markets typically assign non-trivial odds only when forecasts signal anomalous conditions—sustained heat domes, blocked weather patterns, or tropical system remnants. Comparable August markets in prior years have seen probability shifts only when meteorological models flagged departures from the 30-year normal range.

Traders should monitor the National Weather Service Miami office forecasts released 7–10 days before the settlement date, as these typically carry sufficient confidence intervals to move odds. Tropical activity in the Atlantic during early August 2026 could alter local heating dynamics, though direct hurricane impacts would likely trigger market suspension rather than resolution. The German GlüStV regulatory framework and US CFTC reach both recognise weather derivatives as legitimate instruments; this market's sub-$1,500 entry threshold under most no-KYC regimes means accessibility remains broad, though settlement disputes would fall under applicable jurisdiction rules.

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 Kalshi Legal in California has a different geo footprint.

Do I need to KYC for Is Kalshi Legal in California?

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.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Is Kalshi Legal in California 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).
