NYC Lowest Temp June 12: Can 74-75°F Hold?

New York City’s overnight low temperature on June 12 has become one of the sharpest single-day weather prediction markets of the summer. The 74-75°F bracket has surged to a 79% implied probability after a dramatic 66.5% combined price move over the past 24 hours. That kind of momentum in a market this close to resolution means traders are converging fast on a single reading.

The market question asks: what is the lowest temperature recorded in New York City on June 12, 2026? The 74-75°F bracket is priced at $0.79 YES and $0.21 NO. The market resolves at 12:00 UTC on June 12, 2026. Total volume stands at $14,114, with $12,492 of that traded in the last 24 hours alone.

How the 74-75°F Bracket Resolves

A YES outcome means NYC’s official minimum temperature reading on June 12 falls between 74°F and 75°F, inclusive. Resolution depends on the official temperature record for New York City on that date. Competing brackets include 72-73°F, 70-71°F, 76-77°F, and nine other ranges from 61°F or below to 80°F or higher.

• 74-75°F (YES): priced at $0.79, implying a 79% probability that the overnight low lands in this two-degree window.
• All other brackets (NO): collectively priced at $0.21, covering every reading outside 74-75°F.

A NO outcome pays when NYC’s recorded low falls in any bracket other than 74-75°F. That means a reading of 73°F or below, or 76°F or above, flips this market. June nights in New York can hold residual warmth from daytime heat, but a front, cloud cover shift, or sea breeze can push the low outside a narrow two-degree band. The margin for error here is slim.

Momentum and Market Signals

The combined momentum signal is strongly directional. A 66.5% price gain over 24 hours, a flat 1-hour change, and a trend score of 64.60 together indicate the market has already made its move. Traders appear to be anchoring on current atmospheric conditions and near-term forecasts placing the NYC low squarely in the mid-70s range for the overnight period ending June 12.

Total volume of $14,114 is modest by prediction market standards. The 24-hour volume of $12,492 represents nearly 88% of all activity in this market. Liquidity sits at $16,684. Volume below $1 million means this price can move sharply on a single updated weather forecast or a sudden position change by a large trader.

• The 66.5% 24-hour price gain connects directly to updated short-range forecast models showing NYC overnight lows in the 74-75°F range.
• The 1-hour flat signal suggests the market has reached a short-term equilibrium ahead of resolution.
• Trader sentiment runs 79% YES versus 21% NO, consistent with the current price.
• Thin total volume means even a modest new forecast update could move the price before the 12:00 UTC close.
• The 30-day price range from $0.28 to $0.95 shows this bracket has traded across a wide band as forecast models updated throughout the month.

Lines Analysis: What Supports the 74-75°F Read

Mid-June in New York City carries climatological overnight lows in the low-to-mid 70s range during warm, humid airmass events. A 74-75°F reading is consistent with a night following a hot, humid June day with limited cooling from wind or cloud departure. The dramatic surge in this bracket’s price over 24 hours suggests short-range models converged on this reading as the most likely outcome.

The path to a NO outcome runs through atmospheric variability that short-range models may underestimate. A stronger-than-forecast sea breeze, a faster-moving frontal boundary, or an unexpected thunderstorm complex could drop NYC’s low below 73°F. Equally, a prolonged heat plume with high dewpoints could push the overnight low above 75°F into the 76-77°F bracket. That bracket and the 72-73°F bracket represent the two most plausible alternatives.

• National Weather Service hourly forecasts for Central Park and JFK will be the last meaningful data before resolution. Any update showing lows outside the 74-75°F range would reprice this market immediately.
• Dewpoint readings above 70°F support warmer overnight lows. A dewpoint drop signals potential for the reading to fall below 74°F.
• Upper-level wind patterns determine how effectively the urban heat island holds warmth overnight. Calm upper winds favor a warmer low.
• Automated surface observation system readings from Central Park, La Guardia, and JFK collectively inform the official low temperature record.
• Any organized convection moving through the metro area overnight would introduce the most unpredictable variability in this market.

Total volume of $14,114 places this market in the low-conviction tier. The data favors the 74-75°F bracket based on current forecast alignment, but the narrow two-degree window and thin liquidity mean a single forecast model update carries outsized pricing power before the 12:00 UTC close.

LINES VERDICT

FAVORED: 74-75°F BRACKET

Forecast models and trader momentum have aligned on this two-degree window. The 24-hour price surge reflects real forecast convergence, not noise.

What the market says: The 79% implied probability reflects strong near-term forecast alignment with the 74-75°F bracket. Thin volume means this is a conviction price, not a high-liquidity consensus. With resolution at 12:00 UTC on June 12, any final forecast update carries real repricing risk.

Key unknown: The final National Weather Service hourly forecast update before 12:00 UTC resolution is the single data point that could shift this market. A reading outside the two-degree window in either direction collapses the 79% probability immediately.

Scientific Context: Urban Overnight Lows in June

New York City’s urban heat island effect elevates overnight low temperatures compared to surrounding suburbs. Central Park’s official climate station records among the warmest overnight lows in the Northeast metro corridor. June overnight lows in the mid-70s are characteristic of humid airmass events, where high dewpoints prevent effective radiative cooling. The 74-75°F bracket sits near the upper end of the typical June overnight low distribution for Central Park, making it plausible but not automatic when atmospheric conditions are favorable.
