Highest temperature in NYC on July 19?

Platform comparison

Market context

New York City's peak temperature on 19 July 2026 will be measured at LaGuardia Airport and resolved against historical weather data from Wunderground. The settlement window closes at midday UTC, meaning traders must have deposited funds and completed verification well before the final reading is recorded. For UK-based traders using Klarna or SEPA rails, processing times typically add 1–2 business days; those relying on USDC settlement should account for blockchain confirmation windows, particularly during peak network congestion.

July temperatures in New York historically cluster between 82–88°F, with extreme heat events pushing into the low 90s. The 0% crowd probability suggests either no active liquidity at the current price or genuine uncertainty about which temperature band will resolve. Comparable July days at LaGuardia show that 85–90°F ranges account for roughly 60% of outcomes, whilst readings above 92°F occur in roughly 15% of years. The current market depth likely reflects deposit friction rather than fundamental disagreement on weather patterns.

The National Weather Service issues extended forecasts approximately 10 days ahead; traders should monitor their June updates for Atlantic ridge positioning and humidity patterns. Recent summers (2023–2025) have shown increased frequency of 90°F+ days across the Northeast, though individual daily variance remains high. Withdrawal availability on your chosen payment rail—whether Klarna's staggered settlement or SEPA's next-business-day clearing—should factor into position sizing, as locked capital during market resolution reduces flexibility for other trades.
