Highest temperature in Wellington on July 6?

Platform comparison

Market context

Wellington’s July 6 maximum temperature is forecast to hover near 13°C, yet the prediction market for “Highest temperature in Wellington on July 6?” currently prices the YES outcome at 0%, implying the crowd believes the temperature will fall outside any defined range or that the event is unresolved. This stark divergence from the 51% probability assigned to 13°C on Lines.com suggests a market-specific anomaly, possibly tied to conditional token mechanics on Polygon where USDC liquidity is thin or where resolution dependencies on Wunderground data have not yet triggered settlement[3][9].

Historically, July is Wellington’s coldest month, with average highs of 12.2°C (54°F) and lows of 7.2°C (47°F), making 13°C a plausible but not dominant outcome[6]. The adjacent market for July 5 resolved firmly at 14°C with 85% confidence, indicating that temperatures can briefly exceed the monthly average, yet the 0% YES price here may reflect trader scepticism about data availability rather than temperature itself[1]. Such volatility in conditional token pricing often arises when resolution sources lag, leaving traders to hedge on uncertainty rather than meteorology.

Traders should monitor Wunderground’s daily update schedule for NZWN, as settlement hinges on the first published data point for July 6; any delay could freeze liquidity or invalidate conditional positions[2]. Additionally, check the National Weather Service’s real-time observations for Wellington International Airport, where current conditions show 15°C with rising pressure and south-south-westerly winds, hinting at potential warming trends that could shift the market if Wunderground confirms a higher peak[4][5]. No recent news announcements directly impact this event, but the resolution window ending 2026-07-06T12:00:00Z demands close attention to data publication timing.

Methodology

This page reviews Highest temperature in Wellington on July 6? across five venues. The live probability is the Polymarket mid-price, sourced directly from the on-chain Polygon order book; the comparison columns benchmark each venue on fee structure, KYC, settlement currency and payment rails. Every CTA routes to PolyGram, which mirrors the Polymarket order book at 0% fees.

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.

FAQ

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.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

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.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like PolyGram trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
