Singapore July 8 High Temp: Will 31°C Hit?

Singapore sits two degrees north of the equator, and its weather doesn’t do much negotiating. The market for the city-state’s highest temperature on July 8 is pricing 31°C at 40.5% implied probability. That’s not a strong conviction bet. It’s a market acknowledging that Singapore’s daily highs cluster tightly in a narrow band, and picking the exact peak is genuinely hard.

The market question asks which temperature will be the highest recorded in Singapore on July 8, 2026. The 31°C outcome is priced at $0.41 YES and $0.60 NO. The market resolves at 12:00 UTC+8 on July 8. Total volume stands at $2,754 with liquidity at $40,401, which means the order book is deep relative to the trading activity so far.

How the 31°C Contract Works

This contract pays out if Singapore’s peak temperature on July 8 lands exactly at 31°C. Competing outcomes include 30°C, 32°C, 29°C, 33°C, 34°C, and several others on either tail. The resolution source is the market itself, based on reported temperature data for that date.

• 31°C YES is priced at $0.41, implying a 40.5% chance of that exact peak.
• 31°C NO is priced at $0.60, covering all scenarios where the day’s high lands at any other value.

The NO contract pays out when Singapore’s July 8 high comes in at 30°C or below, or 32°C or above. Singapore’s historical July highs typically range from 30°C to 34°C, with 31°C and 32°C being the most common single-day peaks. Any sustained cloud cover, afternoon thunderstorm, or anomalous maritime air mass could push the high down to 30°C. A dry, clear morning with strong solar radiation could push it to 32°C or 33°C. The NO side has a wide target.

Momentum and Market Signals

The one-hour price change is flat at 0.0%, and with only 24 hours of trading data available, the trend score of 33.96 reads as mildly bearish. The market hasn’t moved meaningfully since opening. That stability reflects the simple reality: no new weather data has dropped yet to shift conviction in either direction.

Total volume is $2,754, all of it within the last 24 hours. This is a thin market. Liquidity at $40,401 is unusually deep relative to volume, which means a single informed trader with access to updated Singapore Meteorological Service forecasts could move this price sharply before resolution. When liquidity dwarfs volume by a factor of nearly 15, the price is fragile.

• The 1h change is flat and the trend score sits below 40, signaling no directional push from recent trading activity.
• Volume below $3,000 means this market is sensitive to any single well-informed position.
• The liquidity depth of $40,401 suggests the order book can absorb a meaningful trade, but the current price is not yet market-tested at scale.
• The 31°C outcome sits in the statistical center of Singapore’s typical July range, which is why it draws the most market attention among the competing outcomes.
• Competing outcomes at 30°C and 32°C likely hold the next-highest implied probabilities, splitting the field on either side of this contract.

Lines Analysis: Singapore’s Narrow Temperature Band

Singapore’s Meteorological Service tracks daily maxima at Changi Airport and several island stations. July is a transitional month between the Southwest Monsoon’s core and its tail. Afternoon convective thunderstorms are common, and they cap daytime highs. The climatological mean daily maximum for Singapore in July sits close to 31°C to 32°C. That makes 31°C a structurally reasonable target, but not a dominant one.

The NO side wins any time the high misses 31°C by even half a degree. Singapore rounds temperature readings to one decimal or whole degrees Celsius depending on the reporting format. A day that peaks at 31.5°C could resolve as 32°C. A day with early cloud cover could settle at 30°C. The range of competing outcomes is wide, and NO has a lot of ways to collect.

• Singapore Meteorological Service forecasts for July 7-8 will be the clearest signal to watch. Any forecast citing a strong afternoon thunderstorm probability pushes toward 30°C or 31°C and supports YES at current prices.
• A clear-sky forecast with low relative humidity for the morning hours would favor 32°C or 33°C and pressure YES lower.
• La Nina conditions, if present, tend to increase cloud cover and precipitation over the Maritime Continent, capping Singapore highs in the 30°C to 31°C range.
• ENSO-neutral or weak El Nino conditions suppress convection less and allow higher daytime maxima, favoring 32°C and above.
• A wet July 7 evening followed by clearing skies on July 8 morning is the classic Singapore setup for a 32°C peak, which would resolve this contract NO.

The data here is simple: 31°C is the modal outcome for a typical Singapore July day, but not a dominant one. With $2,754 in total volume, this market is pricing the most statistically central answer to a multi-outcome question. The 40.5% probability reflects both the peak’s frequency and the competition from adjacent outcomes. The data doesn’t care about the politics, and in Singapore’s case, the data is weather models and a narrow thermometer range.

LINES VERDICT

LEAN NO, THIN MARKET

Singapore’s July 8 high landing exactly at 31°C is the most likely single outcome, but competing temperatures on either side collectively dominate. The market is pricing uncertainty, not science, and that uncertainty is spread across eleven possible outcomes.

What the market says: A 40.5% implied probability means traders see 31°C as the best single guess but not a confident majority call. With resolution in less than 48 hours and volume under $3,000, this price can move fast on a single updated forecast.

Key unknown: The Singapore Meteorological Service forecast for July 8, specifically afternoon thunderstorm probability and morning cloud cover, is the single most important data point that would reprice this contract before resolution.

Scientific Context: Singapore’s July Temperature Climatology

Singapore’s daily maximum temperatures in July typically range from 29°C to 34°C, with the distribution centered around 31°C to 32°C. The island’s equatorial position means solar angle is consistently high, but maritime moisture and afternoon convection create day-to-day variability. A single thunderstorm before the daily peak reading can drop the high by one to two degrees Celsius. Here’s what the measurements are telling us: the 31°C target is right in the middle of the July climatology, which is exactly why it draws the most bets in a field of eleven outcomes. What moves this before July 8 is a synoptic-scale weather pattern update, specifically whether a monsoon surge or mesoscale convective system is tracking toward Singapore on July 7 or 8.
