Ankara April 30 High Temp: Will It Hit Twenty-One?

Ankara sits at roughly 900 meters above sea level, and April weather in the Turkish capital is notoriously stubborn. The market for the city’s April 30 high temperature has landed on 21°C as the leading outcome at 47.5% probability, but the NO side holds a slim edge at 52.5%. That gap is razor-thin. With resolution arriving at 2026-04-30 12:00:00, traders have less than 24 hours to find out which side of the thermometer wins.

The market logged $12,233 in volume over the last 24 hours against a total of $13,067 traded across the contract’s life. Nearly all the action happened today. That surge, combined with a 1-hour price jump of +9.0% and a trend score of 59.68, tells a clear story: fresh weather data moved traders fast, and the 21°C outcome absorbed most of that capital.

How the Twenty-One Degree Contract Works

This market asks a single question: will Ankara’s highest recorded temperature on April 30, 2026 land exactly at 21°C? The contract resolves YES if official meteorological data confirms that specific reading. It resolves NO if the high falls at any other value, including 20°C, 22°C, or any other temperature on the outcome list.

• YES price: 0.48 (47.5% implied probability)
• NO price: 0.53 (52.5% implied probability)

The NO side pays out if Ankara’s April 30 high misses 21°C entirely. Ankara’s late-April averages typically cluster between 19°C and 23°C. A slight cooling from a frontal system or an unexpected warm surge both push the reading away from the single-degree target the YES contract requires. The Turkish State Meteorological Service tracks the official station data that would determine resolution.

What Today’s Trading Tells Us

The momentum composite here is hard to ignore. A +9.0% hourly price move, a trend score of 59.68, and essentially all of the contract’s lifetime volume arriving in a single 24-hour window point to one thing: a weather forecast update triggered a rapid repricing. Traders saw something in the model runs for April 30 and moved quickly toward the 21°C outcome.

The $29,629 in available liquidity is thin. At that depth, a single large trade can move the price meaningfully. The $12,233 in 24-hour volume, while active for this market, still sits well below $1 million. That means the current 47.5% probability reflects a small pool of capital, not a deep consensus. Prices here can shift sharply if additional forecast data arrives before the noon resolution deadline.

• The 1-hour price change of +9.0% combined with a trend score of 59.68 points to forecast-driven buying, not speculative drift.
• Total lifetime volume of $13,067 flags this as a thin market where price discovery is incomplete.
• Liquidity at $29,629 means any meaningful new position will visibly move the YES price up or down.
• The 24-hour volume of $12,233 represents roughly 94% of total market activity, confirming this is very late-breaking interest.
• NO holds a marginal 5-percentage-point edge, which is within the noise range for a single-degree weather outcome.

Lines Analysis: Ankara’s April Thirty Setup

Here’s what the measurements are telling us. Ankara’s climatological average high for late April sits close to 20-21°C, which means the 21°C outcome is squarely within the seasonal norm. The recent momentum surge suggests at least one widely-followed forecast model is pointing directly at that temperature. When a market reprices this fast on a weather contract, the driver is almost always a specific model output, not general optimism.

The market is pricing uncertainty, not science. A single-degree weather target is inherently fragile. The reading could land at 20°C or 22°C just as easily, and both outcomes kill the YES position. Ankara’s spring temperature profile is also sensitive to the timing of Anatolian high-pressure ridges and Mediterranean moisture intrusions. Either can shift the April 30 high by one or two degrees from forecast. The NO side stays viable simply because the target is so precise.

• Turkish State Meteorological Service official readings will determine resolution. Any discrepancy between forecast and observed data is the core risk.
• European Centre for Medium-Range Weather Forecasts (ECMWF) and GFS model agreement on the 21°C target would strengthen the YES case before resolution.
• A surface cold front moving through central Anatolia on April 29-30 would drag the high toward 19°C or 20°C, repricing NO sharply higher.
• Persistent high-pressure over the Anatolian Plateau on April 30 would push the high toward 22°C or 23°C, also killing YES.
• The 12:00:00 resolution time means only the morning forecast run matters. Afternoon model updates will arrive after the contract closes.

The $13,067 total volume is too thin to treat the current 47.5% price as a reliable probability estimate. What the price does reflect is that the most active traders today believe 21°C is the single most likely outcome among a wide field of alternatives. That is not the same as saying YES is favored to win outright. The NO side’s slim edge captures the base reality: exact single-degree hits are inherently low-probability events even when the forecast points there.

LINES VERDICT

Forecast Aligned, Precision Uncertain

The data favors 21°C as the modal outcome for Ankara on April 30, but a single-degree weather target in a thin market is not a settled call. The momentum is real, the forecast signal is fresh, and the NO edge is barely statistical.

What the market says: At 47.5%, the market treats 21°C as the most likely single outcome while acknowledging the inherent uncertainty of a one-degree temperature target. With resolution at 2026-04-30 12:00:00 less than 24 hours away and liquidity at $29,629, any late forecast shift could reprice this contract significantly in either direction.

Key unknown: The final ECMWF or GFS morning forecast run for Ankara on April 30 is the single data point that matters most. If model consensus tightens around 21°C overnight, YES pressure builds. If models diverge or shift by even one degree, the NO edge widens fast.

Scientific Context

Ankara’s April temperature record shows high variability driven by its continental semi-arid climate and elevated plateau position. Late April highs have ranged from below 15°C during cold intrusions to above 25°C during early heat events. The climatological expectation for April 30 sits near 20-21°C, which is why the market anchored on that value. But the same variability that makes 21°C plausible also keeps every adjacent outcome competitive. Before 2026-04-30 12:00:00, only the final official station reading from the Turkish State Meteorological Service will close the question.

Frequently Asked Questions

• What does 47.5% probability mean here? It means the market assigns roughly a 47-in-100 chance that Ankara’s April 30 high lands exactly at 21°C, not that 21°C is likely in an absolute sense.
• What does the NO contract pay out on? The NO contract at 0.53 pays out if the official high on April 30 is any temperature other than 21°C, including 20°C, 22°C, or any other listed outcome.
• What data would move this price before resolution? Updated ECMWF or GFS model forecasts showing a clear shift away from 21°C toward 20°C or 22°C would reprice this contract sharply in the hours before the 12:00:00 close.
• When does this contract resolve? Resolution is set for 2026-04-30 12:00:00, based on official Turkish State Meteorological Service temperature data for Ankara on that date.
• Is the $13,067 total volume reliable for pricing? No. At that volume level and with liquidity of $29,629, this market is thin. Prices can move significantly on small trades, and the implied probability is less reliable than in high-volume markets.
