NYC May 27 High Temp: 84-85°F Leads at 28.5%

Tomorrow’s high temperature in New York City has fractured trader conviction across ten separate price bands. The 84-85°F range leads the field at 28.5% implied probability. That number doesn’t signal confidence. It signals a genuinely wide forecast distribution with no dominant outcome.

The market question asks: what will the highest temperature in NYC reach on May 27, 2026? The 84-85°F band trades at $0.29 YES against $0.72 NO. The market closes at noon Eastern on May 27. Total volume stands at $40,347, with $29,740 of that moving in the past 24 hours.

How the 84-85°F Contract Works

A YES resolution requires the official high temperature for New York City on May 27 to land exactly in the 84-85°F range. Any reading below 84°F or above 85°F sends this contract to zero. The contract resolves at noon Eastern on May 27, 2026.

• YES ($0.29): Official NYC high temperature lands between 84°F and 85°F on May 27.
• NO ($0.72): Official NYC high falls outside that two-degree band — cooler or warmer.

The NO case here is structurally straightforward. Eight other active bands compete for probability mass. Late May temperatures in New York can swing meaningfully based on frontal passage, sea breeze timing, and overnight lows. A reading outside 84-85°F doesn’t require an extreme event. It just requires the forecast to land in any of the adjacent bands — and several of those bands (82-83°F, 86-87°F) carry meaningful probability themselves.

Momentum and Market Signals

The combined momentum signal is flat. The 1-hour price change registers zero movement. A 24-hour comparison is unavailable, and the trend score of 26.59 sits in cautious territory. The price has held at $0.29 since the market opened, reflecting stable early positioning rather than any directional conviction from new forecast data.

Total volume of $40,347 with $29,740 arriving in the past 24 hours suggests active but thin participation. Liquidity sits at $41,343. Because total volume is well below $1 million, a single large trade or a sharp forecast revision could reprice this contract quickly. This market is responsive to new data in a way that deeper markets are not.

• The 84-85°F band holds a 28.5% implied probability, the highest single-band reading in the field.
• The 1-hour price change shows no movement, consistent with a stable early forecast window.
• Volume below $1 million means thin liquidity amplifies any repricing from updated NWS forecasts.
• The 24-hour volume of $29,740 reflects fresh positioning, not legacy accumulation.
• Eight competing temperature bands divide the remaining 71.5% probability across a wide range.

Lines Analysis: NYC Temperature on May 27

The National Weather Service forecast for the New York metro area is the single data source that matters here. Late May in New York carries a historical daily average high near 72-74°F, but heat events can push readings well into the mid-to-upper 80s when high pressure builds from the southwest. A 84-85°F reading sits above the seasonal norm but within the range of a typical warm late-May afternoon with inland flow. That’s why the band leads: it represents the most probable single outcome in a wide distribution.

What makes the NO contract realistic is simple arithmetic. The 84-85°F band covers only two degrees out of a possible 20-degree range across all listed bands. Even if the forecast centers near 85°F, operational uncertainty, sea breeze development, and afternoon cloud cover routinely shift the actual high by two to four degrees. The adjacent 82-83°F and 86-87°F bands each carry their own probability mass. A miss of even one degree in either direction costs this contract everything.

• A National Weather Service forecast update pushing the expected high above 86°F would shift volume toward the 86-87°F band and deflate 84-85°F pricing.
• A cooler marine push or frontal passage dropping the expected high to 82-83°F would do the same in the opposite direction.
• Morning temperature readings on May 27 that run warmer than expected tend to support higher-band contracts in real time.
• Forecast model agreement between GFS and Euro models on a specific peak reading would tighten the distribution and briefly boost the leading band.

The $40,347 in total volume reflects a market where traders are actively pricing forecast uncertainty, not a settled scientific outcome. The data currently favors the 84-85°F band as the single most likely reading — but at 28.5%, the market is telling you the forecast is genuinely uncertain across multiple bands. Here’s what the measurements are telling us: the distribution is wide, the leading band is narrow, and this contract lives and dies on the next NWS update.

Leading Band in an Uncertain Field

The 84-85°F band holds the highest single probability in a fragmented market, but 28.5% is a plurality, not a consensus. The market is pricing uncertainty, not science — and the science here is a two-degree window in a forecast that can move.

What the market says: A 28.5% implied probability means this outcome is the most likely single result but still loses more often than it wins. With the market closing at noon Eastern on May 27, any forecast shift overnight reprices every band simultaneously.

Key unknown: The National Weather Service forecast update for New York City on the evening of May 26 is the single most important data point. If the expected high shifts even two degrees in either direction, the leading band changes and this contract reprices sharply.
