NYC July 1 Low Temp: Will It Land at 74-75°F?

Something moved this market fast. The 74-75°F bracket for New York City’s lowest temperature on July 1 opened at $0.31 and jumped to $0.54 within a single hour on June 30. That kind of price surge in a thin weather market almost always traces back to one thing: an updated forecast. The National Weather Service or a major modeling system posted numbers consistent with a warm overnight low, and traders responded immediately. The implied probability now sits at 53.5% for this single temperature bracket.

The market question asks for the lowest temperature recorded in NYC on July 1, 2026, resolving at noon on that date. The 74-75°F bracket trades at $0.54 YES and $0.47 NO. Competing brackets, including 76-77°F and 72-73°F, split the remaining probability. Total volume is $7,225, all of it traded in the last 24 hours.

How This Contract Resolves

Resolution depends on the official low temperature reading for New York City on July 1, 2026. The standard station for NYC weather records is Central Park, monitored by the National Weather Service. The contract resolves YES if the overnight or early-morning low falls specifically between 74°F and 75°F. Any reading at 73°F or below, or 76°F or above, sends this bracket to zero and pays out a competing outcome.

• YES ($0.54, implied 53.5%): The NYC low on July 1 lands at exactly 74°F or 75°F as recorded by the National Weather Service.
• NO ($0.47, implied 46.5%): The NYC low falls outside the 74-75°F range, in any competing bracket from 63°F or below to 82°F or higher.

The NO side wins if forecast models shift, if a cooler air mass arrives overnight, or if the heat holds stronger than expected and the low stays at 76°F or above. The margin between brackets is narrow: two degrees separates this contract from its nearest neighbors. That means even a modest forecast revision can reprice everything.

A Sharp Move on Thin Volume

The 1-hour momentum signal here is unusually strong. A 17.5% price surge, a trend score of 76.85, and all volume concentrated in a single day point to a single catalyst: a forecast update that traders treated as highly credible. Here’s what the measurements are telling us: the market quickly repriced from uncertainty to moderate conviction on the 74-75°F bracket.

Total volume is $7,225 with $14,782 in liquidity. Both figures are well below $1 million. In a market this thin, a single large bet or a new model run published by the National Weather Service or a private forecasting service can move the price by 10 percentage points or more. Treat the current 53.5% probability as directionally informative but not yet stable.

• The 1-hour price move of +17.5% combined with a trend score of 76.85 signals strong short-term buying pressure, likely tied to a forecast model update showing NYC lows near 74-75°F on July 1.
• 24-hour volume equals total market volume, confirming this market effectively launched on June 30 and has no prior price history to anchor expectations.
• Liquidity of $14,782 means the order book is shallow. New forecast data published before July 1 noon resolution can shift price sharply in either direction.
• The competing 76-77°F and 72-73°F brackets are the most likely alternatives if forecast models shift even slightly.
• No whale trades are on record. The current price reflects broad retail-level activity, not institutional conviction.

Lines Analysis: One Forecast Away From a Reprice

The data doesn’t care about the politics, and in a short-range weather market, it also doesn’t care about historical averages. The NWS forecast valid for July 1 is the only signal that matters here. A modeled low of 74-75°F is consistent with a heat event that retains overnight warmth: surface temperatures stay elevated when humidity is high and there is limited radiative cooling. That scenario is realistic for a late-June to early-July heat setup in the New York City metro area.

The NO side becomes real the moment any forecast agency posts a revised low outside the 74-75°F window. A reading of 76°F or higher would reflect an even more intense heat retention event. A reading of 73°F or lower would mean some overnight cooling arrived, potentially from a sea breeze, cloud cover, or a weak frontal passage. The National Weather Service will update its forecast through the evening of June 30, and any revision is a direct market mover.

• National Weather Service hourly forecasts for NYC Central Park: any update showing lows moving to 76°F or above shifts probability to the higher bracket and reprices this contract down.
• Sea breeze development overnight June 30 to July 1: this can pull temperatures lower than models project and boost the 72-73°F bracket.
• High overnight humidity and cloud cover: these factors trap heat and support the 74-75°F or higher range.
• European Centre for Medium-Range Weather Forecasts (ECMWF) and Global Forecast System (GFS) model agreement: if both models converge on 74-75°F overnight, trader confidence in this bracket strengthens.
• Any NWS heat advisory or excessive heat warning issued for NYC before July 1 noon: this would signal strong overnight lows and likely push probability higher for the 74-75°F or warmer brackets.

Total market volume of $7,225 leaves this contract open to rapid repricing. The current data favors the 74-75°F bracket, but the two-degree resolution window is narrow enough that a single model update could move significant probability to an adjacent outcome. The market is pricing uncertainty, not science: the next NWS forecast is what resolves this.

LINES VERDICT

CONDITIONAL LEAN TOWARD YES

The sharp 1-hour surge signals that current forecast models favor a 74-75°F overnight low for NYC on July 1, but the two-degree resolution window and thin volume leave this market highly exposed to any forecast revision before noon.

What the market says: At 53.5% implied probability, the 74-75°F bracket holds a slim majority, reflecting moderate conviction on a warm overnight low. With under $8,000 in volume and resolution in less than 31 hours, this price will move on any new NWS or model update.

Key unknown: The National Weather Service forecast update for NYC on the evening of June 30 is the single most important input. Any shift in the predicted overnight low by even one or two degrees will reprice this market and potentially flip the leading bracket.
