Wuhan July 7 High Temp: Will 31°C Hit?

Wuhan sits in the Yangtze River basin, a city that earns its “furnace” reputation every summer. By early July, daytime highs regularly push into the low-to-mid thirties. The market for July 7 has landed on 31°C as the single most likely outcome, priced at 29%. That is a plurality, not a mandate. Ten outcome buckets splitting the probability space means no single temperature commands a majority, and the data so far is pointing toward a fairly wide distribution of possible readings.

The market question asks for the highest temperature in Wuhan on July 7, 2026, resolving at noon UTC on that date. The 31°C outcome trades at 0.29 YES and 0.71 NO. Total volume sits at just $3,150, all of it within the last 24 hours. That is a thin market. Liquidity reaches $46,774 in the order book, but with volume this low, a single informed weather-watcher can move the price meaningfully before resolution.

How the Contract Works: Wuhan July 7 Temperature Threshold

YES pays out if Wuhan’s official highest temperature on July 7, 2026, is exactly 31°C as reported by the resolution source. NO pays if the recorded high lands anywhere else: 30°C, 32°C, 33°C or higher, 29°C, or lower. The market resolves at 2026-07-07 12:00:00 UTC. Temperature readings for Wuhan typically come from the national meteorological monitoring network, with the official high for the day determined by the peak reading in the daytime observation window.

• YES (31°C): 0.29, implied probability 29%
• NO (any other temperature): 0.71, implied probability 71%

The NO outcome covers nine other buckets. Wuhan’s mid-July climatology puts typical daily highs between 32°C and 36°C, with readings below 30°C uncommon during peak summer. That climatological weight actually pressures the 31°C bucket from both sides. A warmer-than-average pattern pushes probability toward 32°C or 33°C and higher. A brief cloud cover or rain event pulls it toward 30°C or 29°C. Both scenarios pay NO. The 31°C window is only about a two-degree slice of what could be a ten-degree range of plausible outcomes.

Momentum and Market Signals: Thin Volume, Stable Price

The momentum composite for this contract is flat. The one-hour price change registers at zero, 24-hour data is unavailable, and the trend score of 35.51 reflects a subdued, range-bound market. No single catalyst has repriced this contract. The current 29% implied probability has been largely stable, moving modestly from an opening near 25% as the market found its early footing.

Total volume is $3,150, all arriving within the last 24 hours. Liquidity in the order book reaches $46,774, which means the book is deeper than activity suggests. This is a low-volume market by any standard. When volume stays below $1,000 per day, a single trade of a few hundred dollars can shift prices by several percentage points. Any updated weather forecast from China Meteorological Administration or a numerical weather model run showing a temperature signal closer to 31°C would be the most likely trigger for repricing in the next 48 hours.

• Price stability holds: The 1h change is flat at 0.0%, and the trend score at 35.51 points to no strong directional conviction from traders currently active in this market.
• Volume is critically thin: At $3,150 total, this market is highly sensitive to new weather data or any single large position entering the order book.
• Liquidity overhang: The $46,774 in the order book dwarfs actual trading volume, meaning the spread exists but execution risk from a sharp move remains real for late-entry traders.
• No whale trades recorded: The absence of large institutional or high-volume positions means no strong directional signal from experienced traders.
• Resolution window is tight: With two days to resolution, forecast models are entering their most accurate range. Any model update naming 31°C as the central estimate would pressure YES higher quickly.

Lines Analysis: Wuhan Temperature Distribution and the 31°C Bet

Wuhan’s July climatology is the core argument for this market. The city’s historical July 7 temperature distribution, based on decades of station data, clusters most frequently between 32°C and 35°C. The 31°C outcome sits at the cooler edge of the typical range. For YES to pay, conditions need to be slightly below-average for early July but not significantly cooler, which would push the reading to 30°C or below. That is a specific, narrow corridor, and 29% reflects that narrowness correctly.

What makes NO durable here is simple math. Nine other outcome buckets exist. Even if the forecast centers near 31°C, meteorological variability on a single day means readings in the 32°C to 34°C range are statistically more frequent for this date and location. A strengthening subtropical high over central China, which is the dominant driver of Wuhan’s summer heat, would push the high well above 31°C and pay NO. A transient trough or rainfall event is the only realistic path to a sub-31°C reading. Both extremes in either direction pay NO.

• China Meteorological Administration forecast updates: Any official 48-hour forecast centering on 31°C would push YES higher. A forecast above 33°C would suppress it.
• Numerical weather model consensus: If GFS, ECMWF, and CMA models converge on a temperature range that includes 31°C as the central value within the next 24 hours, expect the YES price to rise.
• Synoptic pattern signals: The position and strength of the Western Pacific subtropical high over central China is the primary driver. A weakening or displacement of the high toward the coast would cool Wuhan toward the 30-31°C range.
• Precipitation probability: Any rainfall forecast for Wuhan on July 7 dramatically shifts probability toward cooler outcomes, which pay NO at any temperature below 31°C.
• Early morning temperature trend: Once July 7 begins in Wuhan (roughly 16 hours before resolution), observed morning temperatures will sharply constrain where the daily high lands. Live station data at that point becomes the dominant pricing signal.

The $3,150 in total volume says this market is being watched by a small group of weather-oriented traders, not a broad audience. The data currently favors the NO side broadly, simply because the 31°C slice is one of ten, and Wuhan’s climatology skews warmer than 31°C in early July. The next credible weather model run is the single most important event for this contract before resolution.

LINES VERDICT

NARROW WINDOW, REASONABLE PRICE

The 29% probability on 31°C reflects the math of a ten-bucket market accurately. Wuhan’s July climatology and the dominance of the subtropical high tilt the distribution warmer, making this a precise target in a wide field.

What the market says: At 29% implied probability, the market is not dismissing 31°C but treating it as one plausible outcome among several. With resolution just two days out and volume at $3,150, this price will move sharply the moment an authoritative weather forecast lands. The July 7 end date leaves almost no buffer for correction.

Key unknown: The next operational run of CMA or ECMWF numerical weather models covering July 7 is the single data point that will reprice this contract. If the model consensus shifts the central temperature estimate into the 31-32°C range, YES climbs fast in a thin order book.
