Highest temperature in Miami on August 5?

Platform comparison

Market context

Miami International Airport’s afternoon high for 5 August has settled around the **high-80s to low-90s Fahrenheit** zone, and the market’s current **0% YES** price implies the crowd sees the listed range as effectively out of the money. Against the airport’s August climatology, that is a strong favourite signal for a warm, humid day rather than an extreme-heat outlier: AccuWeather’s August outlook for Miami shows highs of **89°F** on both 5 and 6 August, while airport-area forecasts for the same period sit close to **89°F** with only modest day-to-day variation.[1][11] In handicap terms, the consensus sits with a normal late-summer high, and any value is likely on a contrarian move into a slightly hotter bucket if the afternoon sun dominates before convection builds.[1][11]

Historical framing leans against big upside unless the synoptic set-up is unusually dry. Miami’s August weather is typically hot and humid, with average highs in the upper 80s Fahrenheit, so the “favourite” outcome is usually the central temperature band rather than a breakout reading.[17][10] A recent South Florida forecast noted the region was dealing with persistent warmth and storm chances on 5 August, which matters because cloud cover and afternoon showers can cap the maximum temperature even when the broader air mass is hot.[2][5] That leaves the underdog scenario as a sharp rain-cooled top end, while the value spot is generally whichever band captures an 88–90°F-type peak if the airport stays mostly sunny into early afternoon.[2][5]

For traders, the key catalysts are the timing of sea-breeze thunderstorms, cloud development, and any abrupt shift in radar trends before the daily maximum is set at the airport station.[2][12] Wunderground’s history page for Miami International Airport is the settlement source, so the operative risk is not the forecast headline but the actual recorded high and any late revisions before the next day’s first datapoint appears.[9][7] A forecast that looks routine at dawn can still underperform if convection fires early, which is why the consensus usually stays anchored near the most probable warm-but-not-broiling range rather than chasing the upper tail.[2][5]

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Who Will Win, which mirrors the Polymarket order book directly.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

UK Frequently Asked Questions

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
