Highest temperature in Wellington on July 13?

Platform comparison

Market context

Wellington International Airport is expected to record a maximum temperature near 13°C on 13 July 2026, aligning with the city’s typical midwinter climate where daily highs rarely exceed 15°C. Historical data confirms July maximums average 13.2°C, with extremes seldom surpassing 18°C, making any significant deviation from this range statistically improbable [2][6]. The current 0% crowd-implied probability for a “YES” outcome (presumably a higher-than-expected threshold) reflects this thermal stability, mirroring recent prediction markets on Wellington’s July 6 and July 9 highs, which also clustered tightly around 11–13°C with even odds or slight leans toward the median [7][10].

Traders should monitor real-time Wunderground updates for the NZWN station, as the market resolves solely on its recorded peak, and watch for sudden northerly wind shifts that could briefly elevate temperatures above 15°C. BBC Weather currently reports a high of 13°C with south-south-westerly winds at 24 mph, a pattern that typically suppresses warming [3]. While no major weather announcements are scheduled, funding rates on BTC/ETH perps and USDC liquidity flows on btc-prediction.bet may influence position sizing if a rare heat spike materialises, though whale activity remains muted given the low volatility expectation in this weather contract.

Methodology

This page reads Highest temperature in Wellington on July 13? on-chain. Polymarket's quote comes directly from the Polygon order book — the only comparable venue with on-chain settlement. Kalshi (USD, off-chain), Betfair (GBP/EUR, off-chain) and Manifold (play-money) are listed alongside for venue context. Every CTA routes to BTC Prediction, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.

Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.

FAQ

What are crypto prediction markets?

Crypto prediction markets are on-chain smart contracts where you buy YES or NO shares on a future crypto event (e.g. "BTC above $100k by year-end"). The market price between 0¢ and 100¢ is the implied probability.

Why USDC and not ETH or USDT?

USDC is the Polygon standard — audited reserves (Circle, monthly attestation), deepest order book, low gas costs. ETH volatility would distort probability quotes; USDT has thinner Polygon liquidity than USDC.

What does a transaction cost on Polygon?

Polygon gas is typically under $0.01 per transaction. A full trade cycle (Approve + Order + Fill) totals around $0.03 — compared to $5-50 on Ethereum mainnet.

Can I use Bitcoin directly?

No, Polymarket operates exclusively in USDC on Polygon. You can bridge BTC to USDC via an exchange or bridge service and deposit on Polygon — typically 10-30 minutes processing time.

Are crypto prediction markets taxable in the US?

In the US, prediction market gains are typically treated as ordinary income or short-term capital gains depending on holding period. Consult a tax professional for your specific situation — we cannot provide tax advice.
