Highest temperature in Wellington on July 6?

Platform comparison

Market context

Wellington in July is firmly winter, with daily highs averaging around 53°F (11.7°C), rarely exceeding 57°F (14°C). The current crowd-implied probability of 0% for any specific temperature range reflects the market’s view that no single outcome is dominant, yet historical data shows July 6 typically sees highs near 11–12°C. Comparable cases from recent years, such as July 2, 2026, where 13°C held a 53.5% implied probability, suggest that while 13°C is plausible, it remains a coin flip against other outcomes. The market on Polymarket prices this contract today as a near-even split, with 13°C at 51%—a direct reflection of conditional tokens on Polygon settling in USDC based on Wunderground’s verified daily maximum.

Traders should monitor NIWA’s heatwave forecasts and any sudden shifts in Pacific air pressure, which could push temperatures above the seasonal norm. A recent NIWA report noted Wellington (Kelburn) reached its all-time maximum of 30.3°C in a separate event, highlighting the city’s capacity for extreme spikes despite winter averages. While such extremes are unlikely on July 6, traders must watch for scheduled weather bulletins and real-time Wunderground updates, as conditional token payouts depend entirely on the official daily maximum recorded at Wellington Intl Airport. The settlement window ends 2026-07-06T12:00:00Z, leaving little room for post-event adjustments.

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 Kalshi UK, 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.

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 does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

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