Highest temperature in Miami on August 13?

Platform comparison

Market context

Miami International Airport's highest temperature on 13 August 2026 will be recorded in the Daily Observations table on Weather Underground, with settlement determined by that station's official readings rather than summary figures. The market resolves to a temperature range bracket in degrees Fahrenheit, with the crowd currently assigning zero probability to any outcome—a state that typically reflects either extreme confidence in a particular range or insufficient liquidity to establish consensus pricing.

August in Miami historically produces daily highs between 88 and 94 degrees Fahrenheit, with the National Weather Service recording a median high of approximately 90 degrees for mid-August over the past three decades. The 0% probability reading suggests traders may be waiting for seasonal forecasts or have already settled on a specific range as near-certain; comparable August dates at Miami Intl Airport show minimal variance year-on-year, making historical precedent a stronger signal than for more volatile weather events. The resolution source's explicit reliance on Daily Observations rather than Day High & Low summaries removes ambiguity that sometimes complicates weather settlement disputes.

From a regulatory standpoint, this market's accessibility depends on jurisdiction. Under Germany's GlüStV framework, prediction markets on weather outcomes fall outside gambling regulation if structured as financial derivatives; US CFTC oversight applies only if the platform operates as a designated contract market or derivatives clearing organisation, which most retail prediction platforms do not. For traders in no-KYC jurisdictions permitting stakes up to $1,500 without identity verification, weather markets like this one remain accessible entry points, though settlement verification still requires standard documentation at withdrawal.

FAQ

Do I need to KYC for Is Polymarket Legal in Canada?

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. 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.

What if regulation changes?

If regulation changes in your jurisdiction (e.g. prediction markets are banned), Is Polymarket Legal in Canada would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
