Chengdu July 2 High Temp: Will 31°C Win?

Chengdu sits in the Sichuan Basin, one of China’s most notorious heat traps. The basin geography blocks airflow and amplifies surface heating, pushing summer highs well above regional averages. The 31°C outcome currently prices at 30.5% implied probability, meaning the market treats it as a one-in-three chance for tomorrow’s peak. That’s a competitive field, with outcomes spread across eleven possible temperature brackets from 25°C or below all the way to 35°C or higher.

The market question: what is the highest temperature in Chengdu on July 2? The 31°C outcome trades at 0.31 YES and 0.70 NO, resolving at 12:00 UTC on July 2, 2026. Total volume stands at $33,820, with $24,305 traded in the last 24 hours, suggesting a sharp surge of interest as the resolution date approaches.

How the 31°C Contract Works

YES pays if official temperature records confirm the July 2 daily maximum in Chengdu lands exactly at 31°C. NO pays if the daily high falls on any other bracket: 30°C, 32°C, 33°C, 29°C, 34°C, 35°C or higher, 28°C, 27°C, 26°C, or 25°C or below. Resolution follows the market’s designated data source.

• YES (31°C): 0.31 price, 30.5% implied probability. Pays if Chengdu’s official July 2 high is exactly 31°C.
• NO: 0.70 price, 69.5% implied probability. Pays if any other temperature bracket is recorded.

The NO side wins if Chengdu’s high overshoots into the 32°C-plus range or undershoots to 30°C or below. Early July in Chengdu typically sees highs clustered between 30°C and 35°C, which means the real NO risk is not a cool day but a hotter one. A strong heat ridge or afternoon convective surge could push the bracket above 31°C, making the NO payout the likely result even in a warm scenario.

Momentum and Market Signals

The momentum composite points modestly upward. The 24-hour price change of plus 8.5%, a flat 1-hour reading, and a trend score of 45.21 together suggest a burst of buying interest in the last day without a confirmed directional push in the last hour. That pattern fits pre-resolution accumulation: traders positioning ahead of tomorrow’s measurement window rather than reacting to a new forecast signal.

Total volume at $33,820 is thin. The 24-hour volume of $24,305 represents nearly 72% of all-time volume arriving in the last day alone, confirming this is a market that activated late. Liquidity at $32,377 is reasonable relative to total volume, but thin absolute size means a single large trade can move the price meaningfully. Here’s what the measurements are telling us: this market is pricing uncertainty, not science. With eleven outcomes splitting the probability space, no single bracket commands a dominant share.

• The 24h price change of plus 8.5% reflects late-stage accumulation ahead of the July 2 resolution window, not a shift in meteorological consensus.
• Total volume below $50,000 means this contract has thin liquidity. A single mid-size bet can reprice the 31°C bracket sharply.
• The trend score of 45.21 sits in neutral-to-slightly-bullish territory, consistent with a market that lacks strong directional conviction.
• The 1-hour price change of 0.0% signals the accumulation burst has paused, possibly as traders wait for the next Chengdu forecast update.
• At 30.5% implied probability, the market assigns 31°C roughly equal weight to any two adjacent brackets combined, reflecting genuine distributional uncertainty.

Lines Analysis: Chengdu Basin Heat Dynamics

The bullish case for 31°C rests on Chengdu’s climatological distribution. Early July historically places the daily maximum near the 31°C to 33°C range, with the Sichuan Basin’s trapped heat and high humidity often producing readings in that window. If regional pressure patterns are moderate and cloud cover limits afternoon heating, 31°C becomes a credible central outcome. The data doesn’t care about the politics of which bracket wins; it reflects a basin environment that reliably produces warm but not extreme readings in early July absent a heat wave event.

The primary risk to the 31°C bracket is heat overshoot. Chengdu’s basin geography accelerates warming when synoptic-scale high pressure dominates, routinely pushing highs into the 34°C to 36°C range during heat events. If a strong subtropical ridge is in place on July 2, the heat would most likely land in a higher bracket, paying NO. A cooler scenario, driven by cloud cover or rainfall from the Sichuan basin’s active monsoon interaction, could push the high to 30°C or below, also paying NO. Both directions are plausible, which is exactly why the market spreads probability across eleven brackets.

• China Meteorological Administration forecast updates for Chengdu on July 1 to 2 are the single most important signal. Any forecast shift toward 33°C or higher reprices NO sharply upward.
• Sichuan Basin convective activity: afternoon thunderstorms can cap surface heating, pulling the high toward 29°C to 30°C and away from 31°C.
• Subtropical ridge position over central China: a strengthening ridge favors 33°C or above, a weakening ridge favors sub-31°C outcomes.
• Chengdu Shuangliu International Airport METAR and synoptic surface observation data as the resolution window opens on July 2.
• Any extreme heat advisory issued by Chinese meteorological authorities for Sichuan Province would signal a higher bracket outcome.

Total volume of $33,820 tells us this is a niche, short-duration weather market that activated close to resolution. The distributional spread across eleven brackets means no single outcome has a strong probability edge. The 31°C bracket at 30.5% is the market’s best guess at a central tendency, but the NO side holds 69.5% precisely because the range of plausible outcomes is wide. The data favors caution on any single bracket.

Competitive Single Bracket in a Wide Distribution

The 31°C outcome is the market’s modal pick, but with eleven brackets splitting the probability space and Chengdu’s basin climate capable of both overshooting and undershooting, holding a strong single-bracket position carries real distributional risk.

What the market says: At 30.5% implied probability, the market treats 31°C as the most likely single outcome while assigning nearly 70% combined probability to every other bracket. With resolution in less than 24 hours, volatility will be driven entirely by incoming forecast data and the July 2 observation itself.

Key unknown: The China Meteorological Administration’s final July 2 forecast for Chengdu, and whether Sichuan basin convective activity suppresses afternoon heating or a subtropical ridge pushes the high into the 33°C-plus range, is what will reprice this contract before close.
