Seattle June 16 High Temp: Will 72-73°F Hit?

Seattle’s weather on June 16 has become a short-term prediction market with real money behind it. The 72-73°F band is the current market leader, priced at 43 cents and carrying a 42.5% implied probability. That means traders are saying nearly three-in-five chances that Seattle’s high lands somewhere other than that two-degree window.

The market question is straightforward: what will the highest recorded temperature in Seattle be on June 16, 2026? The primary outcome (72-73°F) sits at $0.43 YES / $0.58 NO, with the market resolving at noon on June 16, 2026. Total volume stands at $18,638, all of it traded in the last 24 hours.

How the Seattle Temperature Contract Works

This contract resolves YES if Seattle’s official high temperature on June 16 falls within the 72-73°F range. Resolution uses the official recorded high for that date. The market closes at noon on June 16, meaning the actual daily high may not yet be set at resolution time.

• YES ($0.43, 42.5% probability): Seattle’s June 16 high lands between 72°F and 73°F inclusive.
• NO ($0.58, 57.5% probability): Seattle’s June 16 high falls outside that range, in any other outcome band.

The NO side pays out across a wide spread of alternatives. The 74-75°F band, the 70-71°F band, and outcomes above 76°F all represent competing brackets. For this specific YES contract to miss, Seattle’s temperature just needs to land one degree off in either direction. Weather prediction markets at this resolution level are structurally sensitive to forecast precision.

Momentum and Market Signals

The trend score of 51.93 is nearly neutral, and the 1-hour price change is flat at 0.0%. The meaningful signal here is the 24-hour jump: the YES price on the 72-73°F band moved up roughly 8.5 percentage points on June 15. That move reflects updated weather forecast data being priced in as the resolution date closed in.

Total volume is $18,638, with all of it arriving in the last 24 hours. Liquidity sits at $60,943, which is healthy relative to volume. Volume below $1 million means this market can reprice sharply on a single updated forecast model or a shift in the National Weather Service outlook for Seattle on June 16. One strong data point moves this.

• The 1-hour price change is flat (0.0%), signaling that the June 15 repricing has stabilized for now.
• The 24-hour price movement (up approximately 8.5 points) was the dominant signal, driven by updated short-range forecasts.
• The trend score of 51.93 indicates no strong directional conviction from the market.
• Liquidity at $60,943 is strong for this market size, but thin total volume means new forecast data will move prices fast.
• Trader sentiment leans bearish at 57.5% NO, suggesting the market sees meaningful probability of a miss in either direction.

Lines Analysis: Seattle Temperature Forecast

The case for the 72-73°F band rests on where current short-range models are pointing. June 16 falls in a shoulder period for Seattle, when marine influence from Puget Sound typically keeps afternoon highs in the low-to-mid 70s. A 72-73°F outcome is squarely in the climatological median for mid-June in Seattle. The price jump on June 15 suggests at least one major forecast model or NWS update confirmed this range as the most likely outcome.

The miss scenario is equally plausible. Seattle’s marine layer can suppress highs into the upper 60s or low 70s on short notice. Alternatively, an inland flow event can push temperatures into the mid-to-upper 70s or beyond. The 74-75°F band is the closest competitor, and the 70-71°F band is a live alternative. Any shift in wind direction or cloud timing could push the high outside the 72-73°F window.

• The National Weather Service Seattle forecast for June 16 is the single most important data point. Any update toward 74°F or higher will reprice this contract sharply downward.
• Marine layer behavior overnight into June 16 will determine whether morning cloud cover suppresses the high below 72°F.
• Upper-level ridge strength over the Pacific Northwest will determine whether the day runs warmer than median forecasts.
• The noon resolution cutoff matters: if the daily high hasn’t been set by noon, resolution may reflect a morning reading rather than the true daily maximum.

The data here doesn’t care about the politics of temperature forecasting. Total volume of $18,638 is thin, and the market is pricing uncertainty across eleven outcome bands. The current pricing reflects a single-model signal that briefly strengthened this band’s probability. Here’s what the measurements are telling us: this is a genuinely competitive multi-outcome market, and no single bracket has commanding probability. The 42.5% implied probability is reasonable for a two-degree window in a city with variable June weather.

LINES VERDICT

NARROW FAVORITE, HIGH UNCERTAINTY

The 72-73°F band holds the highest single probability, but 57.5% of market weight says the temperature lands elsewhere. The market is pricing uncertainty, not science, and the noon resolution cutoff adds structural ambiguity.

What the market says: At 42.5% implied probability, the market rates this band as the most likely outcome but far from dominant. With resolution in less than 24 hours, any NWS update or model shift will move this price fast.

Key unknown: The June 16 morning National Weather Service forecast update for Seattle, particularly any revision to the afternoon high from current projections, is the single data point that would reprice this contract most sharply before noon resolution.

Scientific Context

Seattle’s historical June high temperature averages sit in the low-to-mid 70s, making the 72-73°F band climatologically well-centered. The city’s marine influence from the Pacific and Puget Sound creates meaningful forecast uncertainty within short-range windows. June 2026 follows a period of elevated Pacific sea surface temperatures, which can modestly suppress or extend marine cooling influence on Seattle’s afternoon highs. The range of live outcome bands from 69°F or below to 88°F or higher reflects genuine meteorological uncertainty, not trader noise.

How does the 42.5% probability work?

It means traders currently believe there is roughly a 42-in-100 chance Seattle’s June 16 high falls specifically in the 72-73°F window. The remaining probability is spread across ten other outcome bands.

What happens to my NO contract?

A NO contract on 72-73°F pays out if Seattle’s official high on June 16 falls outside that two-degree range, in any direction. That includes cooler outcomes like 70-71°F and warmer outcomes like 74-75°F or higher.

What data would move this price most?

A National Weather Service forecast update for Seattle on June 16 showing a revised afternoon high above 74°F or below 71°F would immediately reprice this contract. Short-range models are the primary driver.

When does this market resolve?

The market resolves at noon on June 16, 2026. Note that the daily high temperature in Seattle may not yet be recorded by noon, which creates a structural ambiguity in resolution.

Is the volume reliable enough to trust the price?

Total volume is $18,638, all from the past 24 hours. Liquidity is $60,943. Prices here can shift significantly on a single forecast update, so treat the 42.5% figure as a current snapshot, not a stable estimate.
