Guangzhou June 13 Peak Temp: Will 31°C Hit?

A single degree is doing all the work here. Guangzhou’s prediction market for June 13’s highest temperature has swung hard toward 31°C, with the implied probability jumping to 55% after a sharp momentum surge in the past 24 hours. The market opened this contract at 35% and has climbed steadily as traders price in current atmospheric conditions over the Pearl River Delta. One extra degree in either direction — 30°C or 32°C — flips the payout entirely.

The market question asks which single temperature bucket will record Guangzhou’s highest reading on June 13. YES resolves at 31°C. The contract closes at 12:00 UTC+8 on June 13, 2026. Total volume stands at $31,035, with $23,758 of that trading in the last 24 hours alone — more than 76% of all volume concentrated in a single day.

How the 31°C Contract Works

YES pays out if Guangzhou’s official highest temperature on June 13 lands exactly at 31°C, as determined by the resolution source for this market. NO covers every other outcome: 30°C, 32°C, 33°C, 34°C, 35°C, 36°C or higher, 29°C, 28°C, 27°C, or 26°C and below.

• YES (31°C highest temperature): priced at $0.55, implying 55% probability.
• NO (any other temperature): priced at $0.45, implying 45% probability.

The NO side wins if Guangzhou’s peak reading misses 31°C by even a single degree. With ten alternative outcomes on the table, the probability mass is spread thin across a wide range. A 32°C or 30°C reading — both plausible given current conditions — each represent independent paths to NO paying out. The market is essentially betting that weather models have converged tightly enough on 31°C to justify better-than-even odds on a precise one-degree target.

Momentum and Market Signals

The momentum composite here is striking. A 76.54 trend score combined with a 1-hour move of +11.5% and a 24-hour move of +23.5% tells one story: traders are piling in fast, likely responding to short-range forecast models updating on June 12 for the June 13 outlook. When weather markets move this sharply this close to resolution, it usually means forecast convergence — multiple models aligning on a narrow temperature band.

Total volume of $31,035 is thin. Liquidity sits at $53,127, which is healthy relative to volume, but the overall market size means a modest trade can move this price sharply. The $23,758 in 24-hour volume represents a genuine rush of conviction, but context matters: this is not a deep market. New forecast data or a model update issued overnight could reprice this contract dramatically before the 12:00 resolution.

• The 1-hour and 24-hour momentum both point sharply toward YES, consistent with short-range model agreement on a 31°C peak.
• Liquidity ($53,127) outpaces total volume ($31,035), suggesting market makers are holding positions rather than exiting.
• Volume below $1M means this market can move sharply on a single updated forecast or observation report.
• Trader sentiment sits at 55% YES and 45% NO, reflecting genuine uncertainty rather than settled conviction.
• The contract resolves in less than 15 hours from the timestamp — time decay is real, and overnight model runs matter.

Lines Analysis: Guangzhou Temperature on June 13

The case for YES rests on short-range forecast convergence. When a market moves +23.5% in 24 hours on a one-day weather contract, traders are typically front-running a dominant model signal. June in Guangzhou historically sees highs clustering between 30°C and 34°C, with 31°C–33°C representing the most common range during early to mid-June. Here’s what the measurements are telling us: if prevailing forecast models are aligning on 31°C as the likely peak, the 55% implied probability is a reasonable representation of that narrow target within a wide distribution.

The data doesn’t care about the politics — and in this case, the data is a temperature distribution problem. A 31°C reading requires afternoon conditions to stay below the threshold for 32°C. Cloud cover, sea breeze timing from the South China Sea, and residual moisture from recent weather systems all influence whether Guangzhou peaks at 30°C, 31°C, or pushes to 32°C. Any of those alternatives resolves this contract to NO. That’s a real risk with a concrete meteorological path.

• China Meteorological Administration forecast updates overnight for June 13 will be the primary price mover.
• If the Pearl River Delta sea breeze strengthens, it could cap temperatures at 30°C and flip the contract to NO.
• A weakening of overnight convective activity could push the daytime high to 32°C, also a NO outcome.
• The 12:00 resolution cutoff means the market resolves at noon local time — the highest temperature of the morning, not necessarily the full-day peak.
• Any official Guangzhou weather station reading published before the cutoff that contradicts forecasts would reprice this sharply.

The market is pricing uncertainty, not science — and this one is about as uncertain as a one-degree weather call gets. Total volume of $31,035 and the late momentum surge toward YES suggest traders have found a forecast they trust. But at 55%, this is not a settled market. The overnight model run is the single variable that matters most before resolution.

Narrow Forecast Convergence, Real Uncertainty

Guangzhou’s June 13 temperature market has priced 31°C as the modal outcome, but a 55% probability on a precise one-degree target in a ten-outcome market is a thin margin. The momentum surge reflects forecast alignment, not certainty.

What the market says: At 55% implied probability, the market leans toward 31°C but holds genuine doubt. With resolution in hours, any model update or early morning observation shifts this contract fast.

Key unknown: The overnight China Meteorological Administration model run for June 13 is the single most important data point. If it shifts the forecast peak by even one degree, this market reprices immediately.
