Seattle High Temp July 2: Will 64-65°F Hit?

Trader conviction on Seattle’s July 2 high temperature collapsed overnight. The 64-65°F outcome opened at 52 cents and now sits at 31 cents, a drop of roughly 20 points in 24 hours. The market is pricing uncertainty, not science, and right now that uncertainty tilts heavily toward a cooler day than originally expected.

The market question asks whether Seattle’s highest temperature on July 2 will fall in the 64-65°F band. The YES price is $0.31, implying a 30.5% probability. The NO price is $0.70. The contract resolves July 2, 2026. Total volume stands at $28,901, all of it trading in the last 24 hours.

How This Seattle Temperature Contract Works

YES pays out if Seattle’s official high on July 2 lands between 64 and 65°F, inclusive. NO pays if the high falls in any other band: cooler or warmer. Resolution follows verified meteorological reporting for Seattle.

• YES ($0.31, 30.5% probability): The daily high on July 2 registers exactly in the 64-65°F range.
• NO ($0.70, 69.5% probability): The daily high falls anywhere outside that two-degree window, whether 62-63°F, 66-67°F, or beyond.

The NO position wins across a wide spread of outcomes. Seattle could run cooler than 64°F or warmer than 65°F, and NO collects either way. With ten competing temperature bands on this contract, the 64-65°F window carries inherent probability limits. The broader NO side benefits from every outcome that misses this narrow target.

Momentum and Market Signals

The composite signal here is sharply bearish. The 1-hour change sits at -0.5% and the 24-hour change is -21.5%, with a trend score of 49.08, all pointing in one direction. The most likely driver is updated forecast data released around June 30, which shifted expectations toward a cooler July 2 than the market originally priced.

Total volume of $28,901 and liquidity of $44,860 are both thin. This market’s entire trading history compressed into one day. At this volume level, a single large position can reprice the contract sharply. The current 30.5% probability is meaningful as a directional signal, but it does not carry the conviction of a deep-market consensus.

Key Factors

• The 24-hour price drop of 21.5% is the dominant signal. Fresh forecast data almost certainly drove this move.
• The 1-hour change of -0.5% suggests the initial repricing has stabilized, but the trend score of 49.08 shows the market is not recovering.
• Ten competing outcome bands divide probability across a wide temperature range. No single band can dominate without strong meteorological conviction.
• Total volume under $30,000 means liquidity is thin. New weather model data released before resolution could shift this price dramatically.
• The 64-65°F band sits in the middle of the distribution. Cooler forecast revisions would push probability toward the 60-63°F range. Warmer revisions would push toward 66°F or above.

Lines Analysis: Seattle’s July Second Temperature Picture

Here’s what the measurements are telling us. The sharp price decline from 52 cents to 31 cents over 24 hours almost certainly reflects updated National Weather Service model runs showing Seattle tracking cooler on July 2 than earlier forecasts suggested. Seattle’s July climate baseline puts typical highs in the low-to-mid 70s in warm summers, but cooler marine push events regularly drag highs into the low 60s. If the current forecast leans toward a marine layer influence, the probability mass shifts below the 64-65°F window.

The data doesn’t care about the politics, and right now the data is leaning cooler. For the 64-65°F band to resolve YES, Seattle needs to hit a fairly specific target: warm enough to clear 64°F but not so warm that it overshoots 65°F. That two-degree window is narrow. The competing bands at 62-63°F and 66-67°F are the most direct threats, and both have absorbed probability as the 64-65°F price dropped.

Signals to Monitor

• National Weather Service Seattle forecast updates between now and July 2 resolution are the single most important input. Any shift in the high temperature forecast directly reprices this contract.
• GFS and European model agreement on the July 2 high will either confirm or challenge the current bearish lean on this band.
• Marine layer depth forecasts for the Puget Sound region determine whether Seattle holds in the low 60s or climbs toward the mid 60s and above.
• Overnight low temperature on July 1 into July 2 sets the morning baseline. A cold overnight increases the chance the high stays below 64°F.
• Any convective or wind pattern change that breaks the marine influence could push the high above 65°F and shift probability to warmer bands.

Total volume of $28,901 is thin enough that this market is following forecast data more than trader consensus. The current pricing favors outcomes outside the 64-65°F window. The question is whether the high lands cooler or warmer, not whether it misses this band entirely.

LINES VERDICT

NARROW BAND, BEARISH LEAN

The 64-65°F band carries a one-in-three implied probability after a sharp 24-hour selloff. Updated forecast data shifted trader expectations toward outcomes outside this window, and the thin volume means that lean is fragile but real.

What the market says: At 30.5% implied probability, traders see roughly a one-in-three chance Seattle’s July 2 high lands in the 64-65°F range. With resolution less than 24 hours away and thin liquidity, any National Weather Service forecast update could reprice this contract sharply before close.

Key unknown: The final National Weather Service high temperature forecast for Seattle on July 2 is the only thing that matters now. A forecast revision of even two or three degrees in either direction would move probability decisively to a neighboring band.
