Guangzhou May 27 High Temp: 36°C at 31.5%

Guangzhou sits in the Pearl River Delta, where late May temperatures regularly test the upper thirties. The market has priced the 36°C outcome at 31.5% for May 27, making it the single most likely individual bracket in a market where probability is spread across eleven possible outcomes. That dispersal is the whole story here. No single temperature bracket commands a majority, which means the market is pricing genuine meteorological uncertainty, not a settled forecast.

The market question asks: what will be the highest temperature recorded in Guangzhou on May 27, 2026? The YES price for the 36°C bracket sits at 0.32, with NO at 0.69, resolving at noon local time on May 27. Total volume stands at $8,060, with $7,903 of that arriving in the last 24 hours.

How the 36°C Contract Works

YES pays if Guangzhou’s official daily maximum temperature on May 27 lands exactly in the 36°C bracket as recorded by the resolution source. NO covers every other outcome: 35°C and below, or 37°C and above.

• YES (36°C): priced at 0.32, implying a 31.5% probability.
• NO (any other outcome): priced at 0.69, implying a 68.5% probability.

The NO outcome wins across a wide range of scenarios. A cooler-than-expected day pushes resolution toward 34°C or 35°C. A hotter-than-expected day resolves at 37°C, 38°C, or higher. Guangzhou’s late-May climatology puts peak daily highs between 33°C and 38°C, so the 36°C bracket is plausible but competes with at least four other realistic outcomes. The market math reflects that competition directly.

Momentum and Market Signals

The trend score of 56.15 sits just above neutral, suggesting modest directional lean toward YES without strong conviction. No 1-hour or 24-hour price change data is available, so the momentum composite is thin. What is notable is the volume concentration: $7,903 of the $8,060 total arrived in the last 24 hours, indicating this market activated very recently as the resolution date approached.

Liquidity stands at $42,791, which is healthy relative to total volume. Order book depth is not a problem here. But total volume at $8,060 is well below $1 million, which means a single meaningful trade can move the price sharply on any new data, including updated numerical weather forecasts.

• The trend score of 56.15 suggests slight YES lean, but without price change data to anchor it, treat this signal cautiously.
• Volume concentration in the last 24 hours points to late-entry positioning as the resolution date closes in.
• Liquidity at $42,791 means the order book can absorb moderate trades without severe slippage.
• Total volume below $1 million makes this market sensitive to new weather forecast updates or large single trades.
• Trader sentiment is strongly bearish: 68.5% of contract value sits on NO, reflecting the fractured probability landscape across eleven outcome brackets.

Lines Analysis: Guangzhou Temperature Outlook

Late May in Guangzhou historically produces daily highs between 33°C and 37°C, with the 35°C to 36°C range appearing frequently in climatological records for the Pearl River Delta. The 36°C bracket captures a real slice of the probability distribution. If current synoptic conditions over southern China feature a weakening subtropical high with moderate humidity, surface temperatures can easily reach the mid-to-upper thirties before afternoon cloud development caps the peak.

The NO side is strong for structural reasons. The probability is distributed across ten other brackets, not concentrated in one opposing outcome. A 35°C day, a 37°C day, or a 38°C day all resolve as NO. Guangzhou’s diurnal temperature range in late May is typically five to seven degrees Celsius, meaning the forecast margin of error spans multiple brackets. Even a well-calibrated numerical weather model carries uncertainty of plus or minus one to two degrees at this range, which is enough to shift resolution across two or three brackets.

• An updated numerical weather prediction model showing a 36°C peak forecast would push YES price higher before resolution.
• A forecast shift toward 37°C or 38°C, driven by stronger subtropical ridge positioning, would pressure YES downward.
• Rainfall or cloud cover forecast for the afternoon of May 27 would reduce peak temperatures and favor the 34°C or 35°C brackets.
• Any official China Meteorological Administration forecast update for Guangzhou on May 26 or the morning of May 27 would be the most direct signal available.

At $8,060 total volume, this is a lightly traded market. The data favors treating the 36°C bracket as a reasonable but not dominant probability node. The market is pricing uncertainty across a realistic spread of outcomes, not a consensus forecast pinned to 36°C.

LINES VERDICT

CONTESTED BRACKET IN A MULTI-OUTCOME SPREAD

The 36°C outcome is plausible for Guangzhou in late May, but the market structure correctly reflects that plausibility is shared across four or five equally realistic temperature brackets. The data doesn’t care about the politics, and here the data simply cannot isolate one outcome with confidence at this range.

What the market says: At 31.5% implied probability, the market treats 36°C as the single most likely individual outcome while simultaneously assigning 68.5% probability to everything else. With resolution arriving on May 27, any forecast model update in the next 24 hours can reprice this market sharply given the thin total volume.

Key unknown: The China Meteorological Administration’s official point forecast for Guangzhou on May 27 is the single most important data input. A forecast pinned at 35°C or 37°C would immediately shift capital away from the 36°C bracket.

Scientific Context: Late May Temperatures in Guangzhou

Guangzhou’s climate in late May is subtropical monsoon, with mean daily maxima typically ranging from 32°C to 36°C and occasional spikes above 38°C during heat events tied to the East Asian subtropical high. The monsoon onset for the Pearl River Delta region typically occurs between mid-May and early June, meaning pre-monsoon heat events are common in this window. Pre-monsoon days with strong solar radiation and low cloud cover can push surface maxima well above the seasonal mean. The market’s spread across brackets from 33°C to 38°C accurately reflects this climatological variance. Events that would move the price before the May 27 noon resolution include any meteorological authority issuing an official high temperature forecast, a significant shift in the regional pressure pattern visible in model output, or rainfall reports from the Guangzhou area on the morning of May 27.

What probability means here: A 31.5% probability means the market expects 36°C to occur roughly three times in ten similar scenarios. It is the leading bracket but not the favorite to win outright.

How does the NO contract work? NO pays if the recorded daily maximum is any temperature other than 36°C. That includes 35°C, 37°C, 38°C, and every other bracket, giving NO holders ten different winning scenarios.

What data event moves this price? An official China Meteorological Administration forecast update for Guangzhou on May 26 or the morning of May 27 is the most direct catalyst. Numerical weather model output visible on commercial forecast platforms would also move trader positioning.

When does this market resolve? Resolution occurs at noon on May 27, 2026, based on the official recorded daily maximum temperature for Guangzhou as defined by the resolution source.

Is volume reliable here? Total volume at $8,060 is thin. Liquidity at $42,791 is healthy relative to volume, but a single large trade could move the YES price by several percentage points. Treat this price as directionally informative, not precisely calibrated.
