Highest temperature in NYC on August 2?

Platform comparison

Market context

August 2’s outcome depends on the day’s maximum temperature at LaGuardia Airport, with the market settling on the Wunderground history page for KLGA rather than a citywide average or Central Park reading. That matters because airport readings can diverge from Manhattan by a degree or two, and the settlement window ends at noon UTC, so late-morning warming and any afternoon spike still count if they land before the cut-off.

The current 0% crowd-implied YES looks like a funding and access story as much as a weather view: if traders face extra deposits, card friction, or slow withdrawals, liquidity can stay thin even when the forecast is uncertain. In prediction markets, shallow books tend to produce exaggerated near-zero prices until fresh capital arrives through low-friction rails such as Klarna, SEPA, or USDC, which is why payment convenience can matter as much as the meteorology for how quickly a view gets expressed. Recent public market pages already showed clustering around the low-80s Fahrenheit rather than an outright extreme, suggesting traders were not pricing a runaway heat event at the open. [2][6]

For catalysts, the main driver is the intraday forecast path: cloud cover, sea-breeze timing, and any heat advisory or thunderstorm risk can shift the realised high by several degrees. Traders should watch short-range National Weather Service and local forecast updates through the morning, because a sunny, dry early afternoon is the clearest route to an 82–85°F print, while convective cloud build-up would cap the high lower. The wider context is that New York has already seen severe heat this summer, including 100°F readings in early July, so markets may stay sensitive to any renewed hot spell if official forecasts move up from the low-80s.
