Singapore June 10 High Temp: Will 31C Hit?

Singapore sits on a knife’s edge. The 31°C outcome for June 10 carries a 47.5% implied probability, making this one of the tightest temperature calls in recent prediction market history. The market is pricing genuine meteorological uncertainty here, not a settled forecast. A single degree separates the most liquid outcomes, and the 24-hour momentum tells a sharp story.

The market question asks for the highest temperature recorded in Singapore on June 10, 2026. The 31°C outcome is priced at $0.48 YES and $0.53 NO, resolving at 12:00 UTC on June 10. Total volume stands at $15,001, with $9,162 of that changing hands in the last 24 hours alone.

How the Singapore Temperature Contract Works

This contract resolves YES if Singapore’s official peak temperature on June 10 reaches exactly 31°C. Resolution is tied to the official measurement source. The competing outcomes span a wide band: 28°C, 29°C, 30°C, 32°C, 33°C, 34°C, 35°C or higher, 26°C, and 25°C or below each carry their own pricing.

• YES at $0.48 implies a 47.5% chance the daily high lands precisely at 31°C.
• NO at $0.53 implies a 52.5% chance the high falls on any other outcome.

The NO side wins if Singapore’s peak diverges from 31°C in either direction. June in Singapore is deep inside the wet season, but the wet season does not mean cool. Afternoon convective activity can push highs above 33°C on clear mornings, or cap them near 29°C on heavily overcast days. The temperature band from 30°C to 32°C captures the vast majority of historical June readings, which is exactly why this market is so compressed.

Momentum and Market Signals Show Sharp Late Movement

The combined momentum signal is striking. A flat 1-hour change against a 17% surge over 24 hours with a trend score of 49.94 suggests a burst of conviction followed by a pause. The most likely driver is short-range weather model output for Singapore on June 10, which updated in the last 24 hours and pointed toward a 31°C peak under partly cloudy conditions with moderate humidity.

Volume tells the liquidity story clearly. Total volume at $15,001 is below the $1M threshold, which means price here can move sharply on a single significant trade or a new model run. Liquidity at $40,535 is healthy relative to volume, so the order book is not thin, but the market is small. Treat any price movement above 5% as a meaningful signal.

• The 17% 24-hour price surge on the 31°C outcome reflects fresh confidence, not long-standing consensus.
• The 1-hour flatline at 0% change suggests the initial catalyst has been priced in and the market is now waiting.
• Liquidity at $40,535 supports orderly trading but volume below $1M means this market is sensitive to new forecast data.
• Trader sentiment sits at 47.5% YES versus 52.5% NO, essentially a coin flip with a slight lean against 31°C.
• The trend score of 49.94 confirms neutral-to-slightly-bullish momentum on the 31°C outcome.

Lines Analysis: Singapore’s June Temperature Band

Singapore’s Meteorological Service measures peak daily temperatures at Changi and multiple island stations. June climatology puts the mean maximum near 31°C to 32°C, with standard deviation small enough that 30°C and 33°C are both realistic single-day outcomes. The 31°C outcome is the modal forecast range, which explains why it attracted the 17% price jump. Here’s what the measurements are telling us: the short-range models are pointing at a classic maritime equatorial day, not an anomalous heat event or a washout.

The path to NO winning is straightforward. A morning squall line that persists into the afternoon keeps the peak below 31°C, pricing the 29°C or 30°C outcomes into the money. Alternatively, a dry morning with strong solar insolation pushes the peak to 32°C or higher. Singapore’s topography is flat and the island is small, so station-level variance is limited. But June afternoon convection is notoriously hard to pin down 24 hours out. The data doesn’t care about the politics of which outcome you want. Convective initiation timing is the single variable this market cannot resolve with certainty.

Signals to monitor before June 10 resolution:

• Singapore Meteorological Service short-range forecast updates for June 10 afternoon temperatures are the primary price mover.
• ECMWF and GFS model agreement on convective cloud cover for June 10 morning hours will tighten or widen the temperature band.
• Any official heat advisory from Singapore’s National Environment Agency would signal a push toward 33°C or higher outcomes.
• Observed overnight low on June 9 into June 10 serves as a baseline: a warm overnight minimum supports a higher daytime peak.
• Satellite imagery showing clear skies over the Strait of Malacca on June 10 morning would favor the 31°C to 33°C range.

Total volume at $15,001 is thin for a binary outcome this close to resolution. The market is pricing uncertainty, not science. With $9,162 traded in the last 24 hours and resolution in under two days, this contract is in its most volatile window. The data tilts the 31°C outcome toward the center of the probable range, but the 52.5% lean on NO reflects real meteorological uncertainty about whether Singapore’s daily high lands exactly on this outcome versus one degree in either direction.

LINES VERDICT

Coin-Flip Outcome With Real Meteorological Basis

The 31°C outcome sits at the center of Singapore’s June temperature climatology, which is why the market split almost evenly. Neither side holds a commanding edge.

What the market says: At 47.5% implied probability, the market calls this a near-toss-up. With resolution less than 48 hours away and volume below $1M, expect sharp price swings if any updated short-range forecast lands before June 10.

Key unknown: The Singapore Meteorological Service’s next short-range temperature forecast update for June 10 afternoon hours is the single data point that would reprice this contract decisively in either direction.
