NYC High Temp April 25: Will It Hit 50-51°F?

The market has effectively called this one. Traders pushed the 50-51°F outcome for New York City’s April 25 high temperature to 91.5% probability, and that move happened fast. The 24-hour price change of 45.5% is the real signal here. Weather data aligned with that range during the overnight and early morning hours, and the market responded with conviction.

Here’s what the measurements are telling us: the forecast for April 25 in New York City pointed toward a cool, seasonably chilly day with a high temperature settling in the low 50s Fahrenheit. The 50-51°F band captures exactly that scenario. With resolution at 2026-04-25 12:00:00, the window for a dramatic swing has nearly closed.

How the 50-51°F Contract Works

This market resolves YES if the highest recorded temperature in New York City on April 25, 2026 falls within the 50-51°F range. The contract resolves based on official temperature observation. A YES payout requires the mercury to peak inside that two-degree band and go no higher and no lower than 50-51°F at any point during the day.

• YES: $0.92 per share, implying a 91.5% probability that the NYC high lands in the 50-51°F range.
• NO: $0.09 per share, implying an 8.5% probability that the high falls outside that band.

The NO side pays out if the high temperature falls outside the 50-51°F window. That means any reading below 50°F or above 51°F closes this contract in favor of NO holders. The adjacent outcomes, 48-49°F and 52-53°F, are the most plausible alternatives. A late-afternoon temperature surge past 52°F or an unexpectedly cold morning cap below 50°F would hand NO a win.

Momentum and Market Signals

The momentum composite here is unambiguous. The 1-hour change of 0.0%, the 24-hour surge of 45.5%, and a trend score of 64.60 together describe a market that made its move fast and then stopped. That pattern typically means the underlying data arrived, traders priced it in, and conviction hardened. The driver was almost certainly updated National Weather Service model output showing the 50-51°F band as the consensus high for April 25.

Total volume on this contract reached $108,128, with $90,218 of that traded in the last 24 hours. That means roughly 83% of all trading activity happened in a single day. Liquidity sits at $8,887, which is thin. Thin liquidity means a single large order, or a surprising temperature reading, could move the price sharply before resolution.

• 1-hour change of 0.0% signals that the market has found its equilibrium. No new data moved it in the most recent hour.
• 24-hour change of 45.5% marks one of the largest single-day moves in this contract’s history, driven by updated forecast data aligning on the 50-51°F range.
• $90,218 in 24-hour volume shows traders responded aggressively to that forecast signal. Most of the market’s total lifetime volume arrived in one session.
• Liquidity of $8,887 is low enough that a thin book could see sharp price swings if the morning temperature reading diverges from the forecast.
• Open interest of $0 suggests positions are settled rather than building, consistent with a market near resolution.

Lines Analysis: What the Data Supports for the 50-51°F Band

National Weather Service forecasts for New York City on April 25 converged on a high in the low 50s. The 50-51°F band sits directly in that forecast bull’s-eye. Meteorological models showed a cool air mass in place over the Northeast, with limited afternoon warming potential. That setup favors a narrow, low-energy temperature peak, which is exactly what 50-51°F represents.

The conditions that make NO real are real but narrow. A faster-than-expected warm front arrival could push the high above 52°F. An overnight cold reinforcement could cap the daytime high below 50°F. Neither scenario dominated the forecast consensus heading into April 25. The National Weather Service models and private forecast providers both pointed to the low 50s, which means the 50-51°F traders had the data on their side.

• National Weather Service afternoon model runs will be the final arbiter. Any deviation from the 50-51°F range in the last scheduled update before resolution could reprice the remaining liquidity sharply.
• Actual temperature observations from Central Park or the official NYC reporting station will determine resolution. A single degree in either direction matters here.
• Wind patterns and cloud cover on the morning of April 25 will either accelerate or suppress afternoon warming. A clearer-than-expected afternoon could push toward 52°F.
• The adjacent NO outcomes, 48-49°F and 52-53°F, are each priced well below 8.5% in aggregate. The market distributed the NO probability across multiple alternatives, making any single competing outcome unlikely.

The $108,128 total volume and the sharp 24-hour surge tell a consistent story. The data favors YES. The forecast favored 50-51°F, the market priced it, and the remaining uncertainty is weather variability, not model disagreement.

LINES VERDICT

Market Conviction Locked In Before Resolution

The market moved 45.5% in 24 hours and then stopped. That is what conviction looks like when the data and the forecast agree. The 50-51°F outcome has the weight of National Weather Service model consensus behind it, and the market priced that alignment at 91.5%.

What the market says: 91.5% probability for the 50-51°F outcome, up sharply from 27% at market open. With resolution at 2026-04-25 12:00:00 hours away, the window for a dramatic reprice is narrow but not zero. Thin liquidity at $8,887 means a surprising morning temperature reading could still move the price.

Key unknown: The actual temperature observation from the official New York City reporting station on the afternoon of April 25 is the only thing that matters now. If the thermometer peaks at 52°F instead of 51°F, NO wins and the market reprices instantly.

Scientific and Meteorological Context

April 25 in New York City sits in a transitional meteorological window. The historical average high for late April in NYC is in the mid-to-upper 50s Fahrenheit. A 50-51°F reading would represent a slightly below-average day, consistent with a cool air mass rather than a full-spring warmup. The market is not pricing unusual weather. The market is pricing a forecast that landed squarely on a below-normal-but-plausible outcome.

The data doesn’t care about the politics of weather prediction. A 91.5% market probability for a two-degree temperature band reflects one thing: the forecast models converged. If the models are right, YES resolves. If a late atmospheric shift surprises the models, NO has an opening. Before resolution at 2026-04-25 12:00:00, the final National Weather Service model run and the early morning temperature trend are the two data points worth watching.

Frequently Asked Questions

• What does 91.5% probability mean here? The market implies a roughly 91-in-100 chance that the NYC high temperature on April 25 lands exactly in the 50-51°F range. That does not mean certainty. Weather variability alone accounts for the remaining 8.5%.
• How does NO pay out on this contract? NO pays if the highest recorded temperature in New York City on April 25 falls outside the 50-51°F window. Any reading at or above 52°F, or at or below 49°F, resolves the contract in favor of NO holders.
• What data event would most move this contract before resolution? The official temperature observation from the NYC reporting station is the direct resolution input. A National Weather Service model update showing a shift toward 52°F or above 52°F would reprice the remaining liquidity before the official reading arrives.
• When does this market resolve? The market resolves at 2026-04-25 12:00:00. Given that this is midday, the full afternoon temperature peak may not yet be recorded. Resolution mechanics tied to that timestamp are the key structural detail traders should confirm.
• Is $108,128 in volume enough to trust this market’s price? Total volume of $108,128 is moderate for a short-duration weather market. Liquidity of $8,887 is thin. A single large trade before resolution could shift the price meaningfully, so the 91.5% figure reflects current consensus but not an immovable equilibrium.
