Singapore Max Temp on May 5: Will It Hit Thirty-Two?

Singapore sits less than one degree north of the equator, and May is one of its hottest months. The Meteorological Service Singapore tracks daily maximum temperatures against a long-run mean of roughly 31 to 32 degrees Celsius for this time of year. The 32°C outcome carries a 46.5% implied probability right now, with the market tilted slightly toward NO at 53.5%. That gap is narrow enough to matter, and the momentum heading into resolution is pointing upward.

This contract resolves on May 5, 2026 at 12:00:00, based on the highest temperature recorded in Singapore that day. The 32°C outcome is the single most likely bucket in a multi-outcome market, but it is not a majority position. The market is pricing uncertainty, not science.

How the Thirty-Two Degree Contract Works

This is a multi-outcome market on Singapore’s daily maximum temperature for May 5. The Meteorological Service Singapore measures and reports official daily temperature data. The contract resolves to whichever temperature bucket matches the official highest reading.

• 32°C (YES): 0.47 price, 46.5% implied probability. Pays out if the official daily maximum lands exactly in the 32°C bucket.
• 33°C: Separate outcome tracking a one-degree higher reading.
• 31°C: Separate outcome for a one-degree lower reading.
• 34°C or higher: Covers any extreme heat outcome above 33°C.
• 30°C and below buckets: Cover cooler-than-expected outcomes including 30°C, 29°C, 28°C, 27°C, 26°C, 25°C, and 24°C or below.

The 32°C outcome misses when Singapore’s official maximum lands in any adjacent bucket. A reading of 31°C or 33°C is enough to move all capital away from this contract. Singapore’s daily maximum temperatures in early May typically range between 31°C and 34°C, which means three or four competing buckets carry realistic probability. That distribution is exactly why 32°C sits below 50% even as the market’s single most likely outcome.

Momentum and What the Market Is Signaling

Sponsored Partner

The momentum composite here is a clear directional signal. The 1-hour change of +5.0%, the 24-hour change of +10.0%, and the trend score of 53.75 are moving together. That combined push is consistent with traders adjusting toward warmer expected conditions for May 5, possibly tracking regional forecast updates or observed temperature patterns in Singapore over the past 48 hours.

Total volume stands at $20,442, with $17,475 traded in the last 24 hours. That 24-hour figure is nearly 85% of the entire market’s lifetime volume. Liquidity sits at $43,086. This is a thin market. Volume well below $1 million means a single moderate-sized bet can shift the price noticeably before resolution. The price moved roughly 5.5% on May 3 and another 5% on May 4. Those swings on low absolute volume reflect how sensitive this contract is to new information.

Key Factors

• The 1-hour and 24-hour price changes together with the trend score form a single bullish momentum signal, suggesting traders are increasingly confident in a 32°C outcome for May 5.
• Singapore’s Meteorological Service has not issued any unusual heat advisory or forecast deviation publicly visible as of May 4, 2026.
• May historically produces Singapore’s highest daily maxima alongside April, with readings above 34°C possible during prolonged dry spells.
• Thin liquidity of $43,086 means this price can reprice sharply on any forecast update published before 12:00:00 on May 5.
• The multi-bucket structure of this market limits any single outcome’s ceiling. Even strong consensus on a warm day spreads probability across 32°C, 33°C, and 34°C or higher simultaneously.

Lines Analysis: Singapore Temperature on May Fifth

The case for 32°C rests on climatology and the current momentum signal. Singapore’s May daily maxima cluster most densely between 31°C and 33°C based on historical records from the Meteorological Service Singapore. A reading of exactly 32°C is the modal outcome across years of May data. The upward price move over the last 24 hours suggests traders with access to short-range forecast data are moving in this direction, which is a soft signal worth watching in a thin market.

The 33°C or higher buckets represent the primary risk to this contract. Singapore can exceed 33°C in May, particularly during dry southwesterly wind phases that reduce cloud cover and allow intense solar heating. The 34°C or higher bucket captures genuine tail risk. If any regional forecast update for May 5 shows a hot, dry air mass, capital would shift from the 32°C bucket toward higher outcomes. The NO side at 53.5% reflects that dispersed probability across all non-32°C outcomes, not a consensus bet on a cool day.

Signals to Monitor Before Resolution

• Meteorological Service Singapore daily forecast for May 5 published on the evening of May 4 will be the most direct pricing catalyst for this contract.
• NEA Singapore weather updates, particularly any advisory on afternoon thunderstorm suppression, would support higher temperature outcomes and shift probability away from 32°C toward 33°C or above.
• Regional synoptic charts showing a strong high-pressure system over the South China Sea would indicate clear skies and higher daytime maxima.
• Any observed temperature reading from Changi Airport or Tengah weather stations on the morning of May 5 before the 12:00:00 resolution cutoff could allow traders to update ahead of official reporting.
• Precipitation events on the morning of May 5 would suppress the daily maximum and push probability toward 31°C or lower buckets.

At $20,442 in total volume, this market is pricing genuine forecast uncertainty in one of the world’s most consistently warm cities. The data favors 32°C as the single most likely outcome, but the multi-bucket structure means the contract pays only on an exact match. Here’s what the measurements are telling us: Singapore’s climate makes a sub-31°C day on May 5 unlikely, and the real contest is between 32°C, 33°C, and 34°C or higher.

LINES VERDICT

Narrow Edge to Thirty-Two Degrees, With Meaningful Upside Risk

The data doesn’t care about the politics, and here the data says 32°C is the climatologically central outcome for Singapore in early May. Momentum has moved this contract 10% higher in 24 hours, but thin liquidity means that move reflects limited capital, not broad conviction.

What the market says: 46.5% probability for 32°C as Singapore’s May 5 maximum, with slight NO lean at 53.5% reflecting spread across competing temperature buckets. The contract resolves at 12:00:00 on May 5, 2026, and price can shift sharply in the final hours on thin volume.

Key unknown: The Meteorological Service Singapore’s official forecast for May 5, published on the evening of May 4, is the single most important data point before resolution. A forecast above 33°C would reprice this contract significantly lower.

Frequently Asked Questions

• What does 46.5% probability mean here? The market assigns a 46.5% chance that Singapore’s official highest temperature on May 5 lands in the 32°C bucket. Nine other buckets divide the remaining probability.
• What pays out on the NO side? In a multi-outcome market, capital placed on NO for 32°C profits if the official daily maximum is anything other than 32°C, including 31°C, 33°C, or any other bucket.
• What data release would move this price the most? An official Meteorological Service Singapore forecast or observed morning temperature on May 5 would be the most direct catalyst for repricing before the 12:00:00 resolution cutoff.
• When does this contract resolve? Resolution is set for 2026-05-05 12:00:00, based on the official highest temperature recorded in Singapore on May 5 as reported by the designated resolution source.
• Is volume reliable here? Total volume is $20,442, well below $1 million. This is a thin market. Single trades can move the price noticeably, and the 46.5% probability should be read with that liquidity caveat in mind.
