NYC May 17 Low Temp: Will It Hit 68-69°F?

Seven hours separate this market from resolution, and traders are nearly split. The 68-69°F band for New York City’s lowest temperature on May 17 sits at 49.2% probability this morning, a number that reflects genuine atmospheric uncertainty more than any directional conviction. Here’s what the measurements are telling us: late-spring overnight lows in NYC are notoriously difficult to pin down, and a modest pressure gradient difference of a few miles per hour can push a reading across a two-degree threshold with ease.

The contract resolves at 2026-05-17 12:00:00, which means the observation window is already open. The low temperature for a calendar day in NYC typically occurs in the early morning hours, often between 4 and 7 AM. That window has either already passed or is just closing as this analysis goes to press. Whatever the thermometers recorded at Central Park or LaGuardia, that number is close to being locked in.

How the 68-69°F Contract Works

This market asks one specific question: did New York City’s lowest recorded temperature on May 17, 2026 fall within the 68-69°F range? Resolution follows observed meteorological data, likely sourced from official National Weather Service station readings for New York City. The contract closes at noon Eastern on May 17.

• YES (68-69°F low): Priced at $0.49, implying a 49.2% probability that NYC’s overnight low landed in this specific two-degree band.
• NO (any other outcome): Priced at $0.51, implying a 50.8% probability that the low fell outside the 68-69°F range, anywhere from 55°F or below to 72°F or higher.

The NO side wins across a wide range of outcomes. A low of 66°F, 71°F, or anything outside that narrow band all resolve NO. The National Weather Service Central Park Cooperative Observer station is the standard reference for NYC daily temperature records. For the NO outcome to persist, the observed minimum needs to land in any of the ten alternative brackets: 66-67°F, 64-65°F, 70-71°F, 72-73°F, or the outlier ranges at either tail. The market’s near-even split reflects exactly how compressed these two-degree windows are relative to forecast uncertainty at the hourly level.

Momentum and Market Signals

The composite momentum signal here is notable: a 1-hour and 24-hour price change of +18.7% combined with a trend score of 59.95 points to a sharp upward reprice in the past day. That kind of move on a short-duration weather contract typically means one thing: a fresh model run or an updated NWS forecast nudged the expected low directly into the 68-69°F window, and traders responded immediately.

Total market volume sits at $18,283, with $11,982 trading in the last 24 hours. Order book depth shows $16,653 in liquidity. This is a low-volume market by prediction market standards. Thin liquidity means a single mid-sized trade can move the price sharply, so the +18.7% surge may reflect a relatively small number of well-timed bets rather than broad consensus. Treat the current 49.2% with appropriate skepticism about its precision.

• The 1-hour and 24-hour price change of +18.7% reflects a rapid repricing event, most likely tied to an updated NWS short-range forecast placing the low in the 68-69°F band.
• At $18,283 total volume and $16,653 in liquidity, this market is thinly traded. Price can move sharply on a single new data point or weather observation.
• Trader sentiment sits at nearly 49.2% YES and 50.9% NO, a textbook coin-flip market where no side has established meaningful directional conviction.
• The 30-day price history shows the contract opened around 0.38 and dipped as low as 0.29 before surging to current levels, suggesting the 68-69°F range was viewed as unlikely until very recently.
• Resolution is imminent. The low temperature for May 17 in NYC is either already recorded or will be within the next hour, meaning this market is pricing a near-certain observation, not a future forecast.

Lines Analysis: NYC Temperature Low

The NWS forecast for New York City on May 17 has been pointing toward an unseasonably warm overnight period, consistent with a ridge of high pressure keeping temperatures elevated through the early morning hours. A forecast low in the upper 60s aligns with what synoptic-scale models have been showing for the past 48 hours, which explains why traders repriced sharply upward into the 68-69°F band. The data doesn’t care about the politics, and the atmosphere has been running warm across the Northeast this week.

What keeps NO competitive is the precision problem. Even if the atmospheric setup favors a low in the upper 60s, the difference between a 67°F reading and a 68°F reading is meteorologically trivial. A cloudier early morning, a brief sea breeze intrusion, or simply which official station gets referenced for resolution could push the final number one bracket lower into 66-67°F. The NWS Central Park station and the LaGuardia Airport ASOS can differ by 2-3°F on calm nights, and that gap matters enormously in a two-degree bracket market.

• Watch for the official NWS New York daily climate summary for May 17, which will confirm the observed low temperature and directly resolve this contract.
• The Central Park Cooperative Observer station reading is the standard reference. Any discrepancy between stations could affect resolution interpretation.
• A fresh early-morning observation showing temperatures holding at or above 68°F through the predawn hours would confirm YES.
• Any observed dip below 68°F in the NWS climate record for May 17 would push resolution to NO, likely favoring the 66-67°F bracket based on current forecast profiles.

The $18,283 market at 49.2% YES is telling us that traders believe the 68-69°F scenario is roughly as likely as not, consistent with a forecast that points in that direction but cannot guarantee a two-degree landing zone. The data leans YES. The execution risk leans NO.

LINES VERDICT

Too Close to Call at the Bracket Level

The atmospheric setup for NYC on May 17 favors a warm overnight low in the upper 60s, but a two-degree resolution window and thin market liquidity make this a genuine coin flip at the contract level.

What the market says: 49.2% probability that NYC’s low lands in the 68-69°F band, with the remaining 50.8% spread across ten alternative brackets. With only hours until the 2026-05-17 12:00:00 resolution, this price reflects near-real-time observation uncertainty, not forecast risk.

Key unknown: The official NWS daily climate summary for New York City on May 17 is the single data point that resolves everything. Whether the observed low is recorded as 68°F or 67°F determines the entire outcome, and that one-degree difference is within normal station measurement and rounding variation.

Scientific Context

Mid-May temperature lows in New York City have been trending upward over the past three decades, consistent with broader Northeast warming patterns documented by NOAA’s Regional Climate Centers. The climatological average low for mid-May in NYC sits in the low-to-mid 50s°F, meaning an overnight low in the upper 60s would represent an anomaly of roughly 12-15°F above the historical norm. That kind of departure is consistent with the warm spring pattern that has characterized 2026 across the Eastern Seaboard. The market is pricing uncertainty, not science, and the science here says this is an unusually warm night regardless of which two-degree bracket captures the final reading. What would move this contract before resolution is a single official temperature observation, nothing more.

Frequently Asked Questions

• What does 49.2% probability mean here? It means traders currently believe there is roughly a one-in-two chance that NYC’s official low temperature on May 17 falls specifically within the 68-69°F range, not just in the upper 60s broadly.
• What wins the NO contract? Any observed NYC low outside the 68-69°F band resolves NO, including warmer outcomes like 70-71°F or cooler outcomes like 66-67°F. Ten alternative brackets all pay NO.
• What data point moves this market? The NWS official daily climate summary for New York City on May 17 is the resolution trigger. A single observed temperature reading determines the outcome.
• When does this market resolve? The contract resolves at 2026-05-17 12:00:00, meaning the observation window closes at noon Eastern time on May 17, 2026.
• Is the $18,283 volume reliable for pricing? Total volume of $18,283 is low. Thin liquidity means the 49.2% price can shift significantly on a small number of trades, so treat this probability as a rough estimate rather than a precise consensus.
