NYC April 3 High Temp: Will 62-63°F Hit at 26%?

Traders on Polymarket are pricing the highest temperature in New York City on April 3, 2026 at 25.5% for the 62-63°F bracket. That number dropped hard from 50 cents at market open, bottomed near 17 cents, and has clawed back to its current position after a 3.0% gain in the past 24 hours. The market is pricing uncertainty, not science. And right now, the measurements are pointing somewhere specific.

The 62-63°F outcome sits at 26 cents, with NO priced at 75 cents. Total market volume is $62,647 with $33,771 traded in the last 24 hours alone. For a short-duration weather contract resolving on April 3, 2026, that 24-hour surge is the loudest signal in the room. Something moved traders to act, and the most likely driver is updated NWS forecast model output narrowing the temperature range for Thursday.

How the NYC Temperature Contract Works

This contract resolves based on the official highest recorded temperature at a New York City weather station on April 3, 2026. YES pays out if the day’s peak temperature falls within the 62-63°F band. NO pays if the high lands anywhere outside that range, including adjacent brackets like 64-65°F or 60-61°F.

• YES: NYC high on April 3 lands at 62°F or 63°F. Price: $0.26. Probability: 25.5%. Resolves: April 3, 2026.
• NO: NYC high falls outside the 62-63°F range. Price: $0.75. Probability: 74.5%. Resolves: April 3, 2026.

NO buyers need the temperature to land anywhere else. Given eleven active brackets spanning 59°F-or-below through 78°F-or-higher, that is a wide target. The 62-63°F bracket is the single most probable outcome by market price, but 74.5% of capital is betting the high lands in one of the other ten brackets. NO loses only if the thermometer hits exactly 62 or 63 degrees and holds there as the day’s peak.

Momentum and Market Signals

The momentum composite here is unambiguous. The 24-hour price change of plus 3.0%, combined with $33,771 in single-day volume against a total market of $62,647, means more than half of all capital in this contract changed hands in the last 24 hours. That kind of late-stage volume concentration on a short-duration weather market almost always traces back to a forecast update. Here’s what the measurements are telling us: NWS and private forecast models likely tightened their Thursday outlook, and traders repositioned accordingly.

Total liquidity sits at $27,520. This is a thin market. A single $5,000 order can move the price meaningfully. The 28.5% single-day drop on March 31 proves the point. When a forecast update hits, this contract reprices fast and hard. Anyone entering or exiting near resolution should expect wide spreads and sharp moves on any new model run.

• 24-hour price change: Plus 3.0%, driven by forecast model convergence toward the mid-60s range for Thursday.
• 1-hour change: Stable, suggesting the immediate repricing wave has settled and the market is now in a wait-and-see posture ahead of the next NWS forecast cycle.
• Volume concentration: $33,771 of $62,647 total in 24 hours signals a genuine conviction shift, not noise.
• Liquidity flag: At $27,520 available, this market moves on smaller orders. New forecast data before April 3 could gap the price 10-plus points in either direction.
• Related market signal: The April 2 contract is at 100% and April 4 at 99%, suggesting the surrounding days have resolved or are near-certain. That context frames April 3 as the contested day in the sequence.

Lines Analysis: What the NWS Data Supports

The case for YES rests on model consensus. The 62-63°F bracket is the single highest-probability outcome on the board, and the 24-hour volume surge suggests traders have seen something in the latest forecast runs pointing toward the low 60s. April 3 falls within a transitional window for NYC, where surface high pressure and overnight lows in the 40s commonly produce afternoon highs in the 60-65°F band. The data doesn’t care about the politics of whether this is an interesting bet. It cares about the 500mb pattern, the surface dewpoint, and afternoon cloud cover.

The case for NO is structural. Eleven brackets divide the probability space, and even if the 62-63°F range is the most likely single outcome, it still only captures 25.5% of the distribution. The adjacent 64-65°F bracket is likely the next most competitive, and any forecast shift of two degrees pushes capital there. Measurement uncertainty at the station level, surface wind shifts, and cloud timing can all move the actual high by two to four degrees relative to model output. That spread alone explains why NO holds at 75 cents.

• NWS 48-hour forecast: Any update issued before April 3 morning that pins the NYC high at 62-63°F would push YES toward 35-40 cents. A shift toward 64-65°F would reprice YES sharply lower.
• GFS and Euro model agreement: Convergence between the two primary global models on a specific temperature band is the single strongest signal this market can receive. Divergence keeps NO dominant.
• Overnight low on April 2-3: A warmer overnight low limits afternoon mixing and raises the ceiling. A colder low supports a higher daytime peak if sun is present.
• Cloud cover timing: Afternoon cloud arrival cuts the high by 2-4°F in spring transition patterns. Clear skies favor 64°F-plus outcomes.
• April 4 contract at 99%: If the April 4 market has already resolved near a specific temperature, that resolution gives context for the synoptic pattern driving April 3.

The $62,647 total volume for a single-day weather bracket is modest but not trivial. It signals genuine trader engagement with the forecast, not a placeholder market. The data slightly favors 62-63°F as the modal outcome, but the distribution is wide enough that NO remains the rational position until model runs converge within 24 hours of resolution.

LINES VERDICT

LEAN NO, WATCH FOR FORECAST CONVERGENCE

The 62-63°F bracket is the most likely single outcome, but eleven competing brackets make YES a long shot until NWS model output locks in tight. NO at 75 cents reflects that structural reality accurately.

What the market says: At 25.5%, traders acknowledge 62-63°F as the modal forecast outcome but price in substantial spread across adjacent brackets. The April 3 resolution window means any forecast update in the next 24 hours reprices this contract fast.

Key unknown: The 18z NWS model run on April 2 is the single most important data point. If GFS and the Euro model both pin the NYC afternoon high at 62-63°F with low spread, YES moves sharply higher. Divergence between the two models keeps the distribution wide and NO dominant.
