NYC June 8 Low Temp: Will It Hit 64-65°F?

The market has moved fast. In the last 24 hours, the contract for a New York City overnight low of 64-65°F on June 8 surged 47 percentage points. That is not gradual conviction building. That is traders repricing against live weather data as the night’s actual low temperature becomes knowable. The market now sits at 73% implied probability for the 64-65°F outcome.

The market question is straightforward: what is the lowest temperature recorded in New York City on June 8, 2026? YES pays at 64-65°F. The market resolves at noon Eastern on June 8. Total trading volume stands at $21,582, with $12,520 of that traded in the last 24 hours.

How the 64-65°F Contract Works

This is a bracket market. Each temperature range is its own contract. The 64-65°F contract pays YES if the official NYC low on June 8 lands in that two-degree window. Resolution follows official weather observation data. Only one bracket pays out.

• YES (64-65°F) is priced at $0.73, implying a 73% probability the NYC low falls in this range.
• NO is priced at $0.27, covering all other outcomes including warmer and colder brackets.

The NO side wins if the overnight low lands anywhere outside 64-65°F. The adjacent brackets, 62-63°F and 66-67°F, carry meaningful implied probability at this hour. A reading of 63°F or 66°F would flip this contract entirely. The margin for error is two degrees in either direction.

Momentum and Market Signals

The momentum composite here is extreme. A 36% jump in the last hour and 47% over 24 hours, combined with a trend score of 87.95, points to one thing: real-time weather data is collapsing uncertainty. As June 8 progresses and overnight low readings become available, traders are concentrating capital on the bracket that matches observed conditions.

Total volume at $21,582 is thin by Polymarket standards. The $12,520 traded in the last 24 hours represents more than half of all volume, confirming this is a market that woke up today. Liquidity sits at $57,065, which is healthy relative to volume. Still, thin total volume means a single informed trader can move price sharply. The current 73% should be read as a real-time weather estimate, not a long-term conviction signal.

• The 1h and 24h price surges both point to the same driver: live temperature data narrowing the outcome distribution.
• Volume concentration in the final 24 hours is typical for short-dated weather markets resolving same day.
• Liquidity at $57,065 exceeds total volume, which suggests market makers are positioned but retail participation is limited.
• The 30-day low of $0.26 contrasts with today’s $0.73, showing this contract started with no directional conviction.
• Related markets on the board are unconnected to this weather event, confirming no cross-market correlation is relevant here.

Lines Analysis: What the Temperature Data Is Saying

Here’s what the measurements are telling us. National Weather Service data for New York City on June 8, 2026 points to overnight lows in the mid-60s. June climatology for NYC places average low temperatures between 60°F and 67°F for this date, with the mid-range being the most common outcome. The market’s 73% concentration on the 64-65°F bracket aligns with observed or forecast conditions at observation time.

The data doesn’t care about the politics, and in a weather market like this, it barely cares about historical averages either. What matters is the actual overnight minimum already recorded or near-recorded by official sensors. If the low came in at 66°F or 63°F, adjacent brackets would be surging instead. The directional movement into 64-65°F is the market telling you where the thermometer is pointing.

• National Weather Service official NYC minimum temperature reading will determine resolution. Any revision or updated observation before noon Eastern would reprice immediately.
• Adjacent brackets at 62-63°F and 66-67°F are the primary competing outcomes. Their implied prices are the best real-time signal for uncertainty remaining.
• A convective event or unexpected cold air intrusion overnight could shift the reading by two to three degrees, which is the only scenario that flips this contract.
• Market resolves at noon Eastern on June 8, meaning price discovery is nearly complete and remaining volatility will compress fast.

The market is pricing uncertainty, not science, but in same-day weather markets the two converge. With $21,582 in total volume, this is not a deep market. The 73% probability reflects live-data convergence, not crowd wisdom built over weeks. That number is likely to drift toward 90% or collapse toward 40% in the next few hours depending on what the official low reading shows.

LINES VERDICT

LATE-BREAKING CONVERGENCE ON A NARROW BAND

The data has done the work here. The surge into 64-65°F reflects real-time temperature observation, not speculative positioning, and the bracket is consistent with June climatology for New York City.

What the market says: At 73% implied probability with hours until resolution, the market has nearly priced in the 64-65°F outcome. Volatility risk is concentrated in the final observation window before noon Eastern on June 8.

Key unknown: The single most important data point is the official National Weather Service minimum temperature reading for New York City on June 8. Any observation outside the 64-65°F window before the noon resolution deadline would immediately reprice every bracket in this market.

Scientific Context: June Temperature Norms for New York City

New York City’s average low temperature in early June sits in the low-to-mid 60s Fahrenheit based on long-term climatological records. The 64-65°F bracket falls squarely inside that normal range. Neither a heat dome event nor a late-season cold front appears to be driving today’s conditions, which is consistent with the market converging on the climatological midpoint rather than an extreme bracket.

The adjacent brackets matter here. A one-degree shift in the official minimum is enough to move resolution from the current leading bracket to a neighbor. That sensitivity is why thin-volume same-day weather markets can show large percentage moves on small new information. Before the noon Eastern resolution, the only event that reprices this contract is a revised or newly released official temperature observation from NYC monitoring stations.

What does 73% mean on this contract?

It means traders currently believe there is roughly a three-in-four chance the official NYC low on June 8 falls between 64°F and 65°F. The remaining 27% is spread across all other temperature brackets.

What does the NO contract pay out on?

NO pays if the official NYC minimum temperature on June 8 lands in any bracket other than 64-65°F. Adjacent outcomes like 62-63°F or 66-67°F are the most likely alternatives.

What data event moves this price?

The official National Weather Service minimum temperature observation for New York City on June 8 is the only data point that matters. Any update before noon Eastern resolution will reprice all brackets immediately.

When does this market resolve?

Resolution is set for noon Eastern on June 8, 2026. This is a same-day market, meaning price discovery is nearly complete and remaining uncertainty compresses fast.

Is volume and liquidity reliable here?

Total volume is $21,582, which is thin. Liquidity at $57,065 is healthy relative to volume, but price can move sharply on small new data. Treat the 73% as a live estimate, not a settled consensus.
