Will Jeddah Hit 37°C on May 10?

Jeddah sits on the Red Sea coast at the edge of one of the most thermally volatile regions on the planet. Tomorrow, May 10, 2026, traders are betting on whether the city’s peak temperature clears 37 degrees Celsius. At 53 percent implied probability, this market has not reached consensus. The price has moved sharply in the last 24 hours, and the directional lean is building fast.

The contract resolves at 2026-05-10 12:00:00. The outcome is binary: either Jeddah’s recorded high meets or exceeds 37°C, or it does not. With $17,682 in total volume and a 24-hour swing of +24.0 percent, traders are actively repricing this into tomorrow’s close.

How the Jeddah Temperature Contract Works

This contract asks one question: does Jeddah’s highest recorded temperature on May 10, 2026 reach 37°C or above? If the official measurement hits that threshold, YES pays out. If the peak stays at 36°C or below, the market resolves to one of the alternative outcomes: 36°C, 35°C, 34°C, 33°C, 32°C, 31°C, 30°C, 29°C, 28°C, or 27°C and below. Resolution follows the official measurement source designated by the market.

• YES (37°C or higher): Price 0.53, implied probability 53 percent. The favored outcome by a slim margin.
• NO (36°C or below): Price 0.47, implied probability 47 percent. Still a live outcome with meaningful trader support.

The NO side pays out when Jeddah’s peak temperature stays below the 37°C threshold. May is a transition month for Jeddah. The city moves from spring into early summer heat during this window. A day with cloud cover, elevated humidity off the Red Sea, or an unusual atmospheric pattern can suppress the high by one to two degrees. At 47 percent, the market is treating a sub-37°C outcome as nearly a coin flip, which is the correct read for this time of year.

Sharp Momentum, Thin Volume, and What It Means

The momentum composite here is one signal, not three separate data points. A +11.0 percent move in one hour, a +24.0 percent swing over 24 hours, and a trend score of 69.97 all point in the same direction: traders repriced this contract aggressively into the May 9 session. The most likely driver is updated regional weather model output for May 10, which would have become available in the 24-hour window before resolution.

Here is what the measurements are telling us about the money behind this market. Total volume sits at $17,682 with $10,497 traded in the last 24 hours. Liquidity depth is $46,441. That volume figure is well below $1 million, which matters. Thin liquidity means a single large order can shift the price by several points in either direction. The current 53 percent reading reflects the last clearing price, not a deep-pool consensus. A fresh weather data drop or a model update tonight could reprice this significantly before resolution.

• 1-hour change (+11.0%): The single-hour jump signals a catalyst, likely a short-range forecast update placing Jeddah’s May 10 high in the 37-38°C band.
• 24-hour change (+24.0%): The sustained move over a full day confirms this is not noise. Traders have been consistently buying the YES side since May 8.
• Trend score (69.97): Above 50 indicates directional momentum favoring YES. This is a meaningful lean, not a neutral reading.
• Volume ($17,682 total): Below $1 million means price is sensitive to new information. The next weather model run before 2026-05-10 12:00:00 carries outsized influence here.
• Liquidity ($46,441): Order book depth is moderate for a single-day weather contract. Entry and exit are feasible, but spreads can widen fast on late-breaking data.

Lines Analysis: Reading the Jeddah Data

Jeddah’s May climatology supports the YES side as the base case. Historical temperature records for the city show that mid-May highs regularly reach the upper 30s. The Saudi Presidency of Meteorology and Environment tracks Red Sea coastal temperatures closely during this period, and regional forecast models for the Arabian Peninsula have shown above-average surface temperatures in spring 2026. The +24.0 percent price move over 24 hours aligns with updated forecast output, not random noise.

What makes the NO outcome real is Jeddah’s coastal position. Red Sea sea-surface temperatures and onshore flow patterns can cap daytime highs even when inland Arabia is running hot. A persistent westerly or sea-breeze intrusion on May 10 could hold the peak at 35°C or 36°C. At 47 percent, the market is correctly pricing that barrier as non-trivial. One degree of difference between YES and NO is well within the uncertainty band of any 24-hour regional forecast.

• Saudi Presidency of Meteorology and Environment forecast output for May 10 is the single most important data source before resolution.
• European Centre for Medium-Range Weather Forecasts and GFS model runs published tonight will update the probability band for Jeddah’s peak temperature.
• Red Sea sea-surface temperature anomaly data, if above the seasonal average, supports the YES side by reducing the marine cooling effect.
• Any dust event or Shamal wind pattern over western Saudi Arabia on May 10 could push temperatures above the threshold faster than models predict.
• A measurable increase in cloud cover or onshore humidity on the morning of May 10 would weigh against the YES outcome and support the 35°C-36°C range.

The $17,682 in total market volume reflects genuine trader activity, not a deep institutional consensus. The data currently favors YES at 53 percent, driven by Jeddah’s seasonal climatology and the recent forecast signal embedded in the price momentum. The NO side at 47 percent is not a long shot. It is a reasonable bet on the margin of error in any short-range temperature forecast for a coastal city.

LINES VERDICT

Narrow YES Lean, Weather-Dependent

Jeddah’s May climatology and the sharp 24-hour price movement both favor the 37°C threshold being reached. The data doesn’t care about the politics, and right now the data is pointing at a warm May 10.

What the market says: 53 percent probability that Jeddah hits 37°C or higher on May 10. The market is pricing uncertainty, not science. With resolution at 2026-05-10 12:00:00 and volume below $1 million, any final weather model run before midnight could shift this price materially.

Key unknown: The last regional forecast model output before the May 10 resolution window is the single variable that will reprice this contract. If the Saudi Presidency of Meteorology and Environment or the ECMWF short-range run tonight shows a coastal sea-breeze pattern, the NO side gains ground fast.

Scientific Context: Jeddah in May

Jeddah’s position at 21 degrees north latitude on the Red Sea coast places it in a thermal environment that transitions sharply from spring to summer in May. The city’s average May high sits near 36°C, with frequent days exceeding that average as the season progresses. The 37°C threshold in this contract sits just above the monthly average, making it a genuine statistical question rather than an extreme event call. Regional climate data for 2025 and early 2026 showed elevated Arabian Peninsula temperatures consistent with a warm spring pattern. That context supports the YES probability holding above 50 percent, but does not make it a certainty. The coastal modifier is real, and the market’s 47 percent NO probability reflects that accurately.

Frequently Asked Questions

• What does 53 percent mean here? It means the market assigns a 53 percent chance that Jeddah’s recorded high on May 10, 2026 reaches or exceeds 37°C. The remaining 47 percent covers all cooler outcomes.
• How does the NO outcome pay out? The NO side, representing any outcome at 36°C or below, pays out if Jeddah’s peak temperature on May 10 stays under the 37°C threshold. The market resolves to whichever specific temperature band is recorded.
• What data event would move this price most? A short-range weather model update from the European Centre for Medium-Range Weather Forecasts or the Saudi Presidency of Meteorology and Environment, published before the May 10 resolution window, carries the most influence on this contract.
• When does this contract resolve? The market resolves at 2026-05-10 12:00:00. Given the single-day window, resolution is imminent and price movement will compress as the deadline approaches.
• Is the volume reliable for reading the market? Total volume of $17,682 is below $1 million, which means this is a thin market. Prices can shift sharply on a single order or new data release. The 53 percent reading is directionally useful but should not be read as a deep-pool consensus.
