Highest temperature in Lucknow on August 17?

Platform comparison

Market context

On 17 August 2026, the highest temperature recorded at Chaudhary Charan Singh International Airport in Lucknow will fall into one of several defined ranges. The resolution mechanism specifies the Daily Observations table on Weather Underground as the authoritative source, rather than the Day High & Low summary—a distinction that matters when automated feeds or manual transcription introduce variance. For programmatic traders, this means building a parser that targets the specific table structure rather than relying on summary endpoints, which may round or aggregate differently.

Lucknow's August climate sits in the tail end of the monsoon season, with historical highs typically between 32–36°C. The current 0% crowd probability suggests either extreme confidence in a specific range or insufficient liquidity to establish baseline odds. Comparable August 17th data from prior years provides calibration: checking Weather Underground's historical records for the same station across multiple years establishes the distribution of outcomes and identifies whether the market's range boundaries align with observed variance. A trader evaluating this market should cross-reference at least five years of historical daily maxima to assess whether the offered ranges cover realistic scenarios.

The critical dependency is Weather Underground's data pipeline and any station maintenance or sensor recalibration scheduled near the settlement date. Monsoon intensity forecasts from India Meteorological Department releases in early August will signal whether conditions favour the lower or upper end of typical ranges. Traders should monitor for any station outages or data gaps that might delay resolution; setting conditional orders tied to IMD rainfall forecasts provides a systematic approach to position sizing as the event date approaches.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
