Ankara May 31 High Temp: Will It Hit Twenty-One Celsius?

Ankara’s weather markets rarely generate this kind of momentum. The contract for a 21°C daily high on May 31 has jumped 13% in the last 24 hours, driven by what appears to be a convergence of regional forecast models tightening around that specific threshold. The market is pricing this outcome at 43.5% probability. That’s a meaningful signal — not a lock, but not noise either.

The market question asks: what will be the highest temperature recorded in Ankara on May 31? The 21°C outcome trades at 0.44 (YES) against 0.57 (NO), with resolution set for May 31 at noon UTC. Total volume stands at $8,721, with $6,749 of that arriving in the last 24 hours.

How the Twenty-One Celsius Contract Works

This is a single-outcome selection from a multi-bucket temperature market. Traders pick the exact degree bucket they believe Ankara’s maximum temperature will land in on May 31. Resolution happens at noon on May 31, based on recorded meteorological data for the day’s peak temperature.

• YES (0.44): Ankara’s highest temperature on May 31 is exactly 21°C.
• NO (0.57): Ankara’s highest temperature on May 31 lands in any other bucket — including 20°C, 22°C, 19°C, 23°C, 18°C, 25°C or higher, 17°C, 24°C, 16°C, or 15°C and below.

The NO side wins across a wide range of outcomes. Any forecast shift — warmer or colder — routes value away from the 21°C bucket. Ankara sits at roughly 938 meters elevation on the Central Anatolian Plateau. Late May temperatures at this elevation can swing 4 to 6 degrees across a single forecast window, especially when pressure systems move through the region. That spread is what makes multi-bucket markets like this genuinely competitive.

Momentum and Market Signals

The combined momentum signal — flat over the last hour, up 13% over 24 hours, trend score at 49.17 — reads as a fast move that is now consolidating. The most likely driver is a forecast update published Thursday that nudged Ankara’s May 31 high closer to the 21°C mark. Traders followed quickly. The hourly plateau suggests the initial positioning is done.

Total volume at $8,721 is thin. The $6,749 that arrived in the last 24 hours represents most of the market’s lifetime activity. Liquidity is deep at $57,280, which is unusual relative to volume — this means the order book can absorb new trades without major price moves, but the thin volume also means a single large position could shift the implied probability materially before resolution.

• The 24h momentum surge of 13% aligns with a forecast cycle update, not organic trader conviction building over days.
• The 1h flatness after a sharp daily move suggests initial re-pricing is complete pending new forecast data.
• Total volume below $10,000 means this contract’s price is sensitive to single-trade shocks. Liquidity depth at $57,280 provides some buffer, but thin volume is the dominant dynamic here.
• The trend score of 49.17 sits near neutral — no strong directional conviction from the momentum composite alone.
• Ankara’s late-May climatology typically places daily highs between 20°C and 25°C, making the 21°C bucket plausible but not dominant in a uniform distribution across the range.

Lines Analysis: What the Forecast Data Is Saying

The case for the 21°C bucket rests on current forecast model clustering. When multiple forecast ensembles agree on a narrow temperature range, markets like this tend to concentrate probability in one or two adjacent buckets. The 13% single-day move suggests at least one data update moved the consensus closer to 21°C than it was 48 hours ago. Here’s what the measurements are telling us: Ankara’s synoptic setup for late May 31 appears to favor mild, below-seasonal-peak temperatures, which is consistent with a 21°C ceiling rather than a push toward the mid-20s.

What makes the NO side real is the width of the alternative outcome range. Even if 21°C is the most likely single outcome, it does not need to be wrong by much. A 22°C or 20°C reading — separated by just two degrees — each pay out for NO holders. Ankara’s topographic variability and afternoon convective patterns mean that small forecast errors have outsized electoral power in a market structured this way. The NO bucket is not betting against one temperature. It is betting against one specific number while holding nine other winning conditions.

• Next forecast cycle update for Ankara’s May 31 high: any major model run showing a shift above 22°C or below 20°C would reprice the 21°C contract sharply downward.
• Regional pressure system movement: a trough deepening over central Anatolia overnight May 30 to May 31 would cool the forecast and shift probability toward the 19°C and 20°C buckets.
• Morning temperature trajectory on May 31: if Ankara’s observed 9 AM temperature is tracking well below the 21°C target, the contract will likely price down before noon resolution.
• Thin volume sensitivity: a single $500 to $1,000 trade in this market could shift implied probability by several percentage points before resolution.

The data doesn’t care about the politics — or in this case, the trader positioning. Total volume at $8,721 reflects a market that has attracted interest but not deep conviction. The 21°C outcome is the market’s current best guess for Ankara’s May 31 peak, but the structure of the contract gives NO holders a significant probability advantage simply through the number of winning buckets they hold. The data favors treating this as a competitive single-outcome bet in a wide field.

LINES VERDICT

COMPETITIVE — FORECAST-DRIVEN

The 21°C outcome is the most likely single bucket given current forecast clustering, but it competes against nine alternatives in a market where a two-degree miss in either direction is entirely routine for Ankara in late May.

What the market says: 43.5% implied probability — traders see this as the most probable single outcome but far from certain, and the thin volume means this price can shift meaningfully on any new forecast data before noon resolution on May 31.

Key unknown: The final forecast model run for Ankara on the morning of May 31 is the single data point that will reprice this contract. Any model consensus shift above 22°C or below 20°C collapses the 21°C bucket’s probability before the market closes.

Scientific Context: Ankara’s Late-May Temperature Baseline

Ankara’s late-May climatology places mean daily highs in the 22°C to 25°C range, with significant variability driven by the city’s plateau elevation and Central Anatolian pressure patterns. The 21°C outcome sits slightly below the long-run seasonal average for this date, consistent with a cooler-than-average late-May setup. That positioning is plausible but not the baseline expectation. Events that would move the price before resolution include any operational forecast issued on the morning of May 31 showing Ankara’s high drifting above 22°C, which would shift volume toward adjacent buckets and reprice this contract below 30%.

How accurate is a 43.5% probability on a temperature bucket?

It means traders collectively assign roughly four-in-ten odds to the 21°C exact outcome. In a ten-bucket market, 10% would be a flat prior. A 43.5% share means 21°C is the market’s modal forecast by a significant margin.

What does NO pay out on?

NO wins on any of the nine other temperature outcomes: 20°C, 22°C, 19°C, 23°C, 18°C, 25°C or higher, 17°C, 24°C, 16°C, or 15°C and below. NO holders need the temperature to land anywhere except exactly 21°C.

What would move the 21°C contract price before resolution?

A forecast model update shifting Ankara’s May 31 high above 22°C or below 20°C would reprice this contract downward sharply. Any observed morning temperature on May 31 tracking outside the 19°C to 22°C range by 9 AM would do the same.

When does this market resolve?

Resolution is set for May 31 at noon UTC. The market closes and settles based on the recorded maximum temperature in Ankara for that calendar day up to the resolution window.

Is the volume here reliable enough to trust the price?

Total volume is $8,721, with most arriving in the last 24 hours. Liquidity is deep at $57,280, but thin volume means the price is sensitive to small individual trades. Treat the implied probability as directional, not precise.
