Lines Verdict
YES at 100% implied probability

MARGINAL FAVORITE: The 31°C bucket holds the slimmest edge based on current eastern Mediterranean forecast patterns, but the one-degree resolution structure and near-coin-flip odds make adjacent buckets nearly as likely. Market probability: 50.5%.

Tel Aviv sits at the edge of a summer heat pattern that makes a single-degree call genuinely difficult. The market for the city’s highest temperature on July 4 has landed at 50.5% for 31°C, with eleven discrete outcome buckets splitting the rest of the probability. That near-coin-flip reading is not confusion. It is an honest reflection of how tight Mediterranean summer forecasts get when you slice them to one-degree resolution.

The market question asks: what will the highest temperature in Tel Aviv reach on July 4, 2026? The 31°C outcome is priced at $0.51 YES, $0.50 NO, with an implied probability of 50.5%. The contract resolves on July 4, 2026 at 12:00 UTC. Total volume stands at $7,941.

How the Thirty-One Degree Contract Works

A YES outcome pays if Tel Aviv’s verified daily maximum temperature on July 4 lands exactly at 31°C. The resolution source is market resolution, meaning the operator will use an official or widely accepted temperature record for the city. Competing outcomes include 32°C, 30°C, 33°C, 29°C, 28°C, 34°C, 35°C, 36°C, 27°C or below, and 37°C or higher.

  • YES at $0.51: Tel Aviv hits a daily high of exactly 31°C on July 4.
  • NO at $0.50: Tel Aviv’s daily high falls on any other outcome bucket, from 27°C or below up to 37°C or higher.

The NO side covers ten other temperature outcomes. A miss by a single degree in either direction pushes the full payout to a competing contract. That structural feature is what makes 50.5% a reasonable anchor. Historical Tel Aviv July highs cluster between 29°C and 34°C, but the Mediterranean sea breeze and synoptic pressure patterns can shift that range by two to three degrees within a week.

Momentum and Market Signals

The momentum composite here is low-signal. The 1-hour price change is flat at 0.0%, the trend score sits at 22.45, and 24-hour change data is unavailable. What drove the market open was a 9% price move on July 2, which lifted the 31°C outcome from $0.50 to its current level. That move likely tracked early numerical weather prediction model output pointing toward a mid-thirty-degree synoptic pattern over the eastern Mediterranean for the July 4 period.

Total volume is $7,941 and 24-hour volume is $7,951, which is essentially the full market depth traded in a single day. Liquidity stands at $66,524, which is healthy relative to volume. The market is thin in dollar terms, though. Volume below $10,000 means a single moderate-sized trade can reprice any outcome bucket meaningfully. Take price swings in this contract as directional signals, not settled conviction.

  • The 31°C bucket gained approximately 9% on July 2, suggesting early forecast data favored that range.
  • The 1-hour change is flat, which means no new forecast signal has hit the market in the most recent trading window.
  • Liquidity at $66,524 is six times the traded volume, giving the order book enough depth to absorb moderate-sized trades without extreme slippage.
  • Trader sentiment reads 50.5% YES to 49.5% NO, a near-perfect split that reflects genuine forecast uncertainty at one-degree resolution.
  • The trend score of 22.45 is modest, consistent with a market that moved on an early forecast catalyst and has since stabilized while waiting for model updates.

Lines Analysis: What the Eastern Mediterranean Pattern Says

July in Tel Aviv is defined by the Sharav, a dry hot easterly wind from the Arabian interior, and by the Mediterranean sea breeze that moderates coastal temperatures in the afternoon. NOAA and European Centre for Medium-Range Weather Forecasts ensembles for the eastern Mediterranean in early July 2026 have been tracking a moderate ridge of high pressure over the region. That pattern typically produces daily highs in the 30°C to 33°C corridor for coastal Tel Aviv. The 31°C outcome sits near the lower end of that likely range, which explains why the July 2 move brought it to roughly even odds.

What makes the NO outcome real is the spread across competing buckets. Even if the ridge holds, a stronger-than-expected sea breeze could cap the high at 29°C or 30°C. A deeper Sharav intrusion could push the reading to 33°C or 34°C. The Israel Meteorological Service publishes daily updated forecasts, and any model shift toward a stronger Sharav by July 3 would move capital out of 31°C and into higher-outcome buckets. The reverse, a strengthening coastal trough, would shift probability toward 29°C or 30°C.

  • Israel Meteorological Service forecast updates on July 3 are the single most important data input before resolution.
  • European model ensemble output for July 4 eastern Mediterranean surface temperature: a shift of plus or minus two degrees in the model mean would materially reprice the 31°C bucket.
  • NOAA GFS model alignment with European models: agreement between the two would compress uncertainty and sharpen the leading outcome’s probability.
  • Sea surface temperature anomalies in the eastern Mediterranean: warmer-than-average SSTs weaken the sea breeze and bias highs upward.
  • Synoptic pressure gradient on July 3: a deepening Cyprus Low would cool coastal Tel Aviv; a strengthening Azores-Arabian ridge would warm it.

The $7,941 in total volume signals a niche market with limited liquidity depth per outcome. The data through July 2 favors the 31°C reading as the single most probable outcome, but with a probability barely above a coin flip, the adjacent 30°C and 32°C buckets are nearly as likely. No single outcome is a dominant bet here. The market is pricing the full distribution of a short-range weather forecast, not a settled scientific consensus.

LINES VERDICT

Marginal Favorite, Wide Distribution

The 31°C outcome holds a slim edge based on current forecast patterns over the eastern Mediterranean, but the one-degree resolution structure means neighboring buckets absorb nearly as much probability.

What the market says: At 50.5% implied probability, the market is essentially calling this a toss-up between 31°C and the adjacent temperature buckets. With two days to resolution and thin total volume, any updated model run on July 3 can move this price sharply.

Key unknown: The Israel Meteorological Service forecast update on July 3 and the final European and GFS model ensemble alignment for July 4 are the decisive inputs. A Sharav strengthening signal would shift money toward 32°C and 33°C; a sea breeze signal would shift it toward 29°C and 30°C.

This analysis reflects market conditions as of July 2, 2026. Prediction market probabilities are volatile and shift as new data and regulatory decisions emerge, especially as the July 4, 2026 resolution date approaches.

Frequently Asked Questions

It means the market assigns a roughly coin-flip chance that Tel Aviv's highest temperature on July 4 lands exactly at 31°C. Ten other outcome buckets share the remaining 49.5% of probability.

NO pays out if Tel Aviv's July 4 daily high lands on any bucket other than 31°C, including 30°C, 32°C, 33°C, or any other listed outcome. A one-degree miss in either direction is enough.

Israel Meteorological Service forecast updates and European and GFS model ensemble output on July 3 are the key inputs. A stronger Sharav signal would push probability toward higher buckets; a coastal trough signal toward lower ones.

The contract resolves on July 4, 2026 at 12:00 UTC, using an official or widely accepted temperature record for Tel Aviv's daily high.

Total volume is under $10,000, which is thin. Liquidity at $66,524 exceeds traded volume, but a single moderate trade can shift any outcome bucket's price. Treat price moves as directional signals, not firm consensus.

What Could Shift These Probabilities?

Ridge Holds, Sea Breeze Moderates

If the moderate eastern Mediterranean high-pressure ridge holds through July 4 and the afternoon sea breeze keeps coastal Tel Aviv from overshooting, the daily high lands cleanly at 31°C. European and GFS model agreement on this outcome would push the 31°C bucket well above 60%, drawing capital from the 30°C and 32°C buckets.

Sharav Pushes the High to 33°C or Above

A strengthening Sharav, the dry easterly wind from the Arabian interior, could override the sea breeze and push Tel Aviv's July 4 high into the 33°C to 35°C range. Any model run on July 3 showing a deeper Sharav intrusion would shift probability rapidly out of 31°C and into higher outcome buckets, collapsing the current 50.5% reading.

Coastal Trough Drops the High to 29°C or 30°C

A stronger-than-forecast coastal trough or a deeper Cyprus Low developing on July 3 could cap Tel Aviv's high at 29°C or 30°C. That scenario would redirect capital away from 31°C into lower outcome buckets. The 30°C bucket is currently the most obvious beneficiary if models shift cooler.

Dust Event or Khamsin Disrupts the Pattern

An unforecast Khamsin or regional dust storm arriving on July 4 could suppress daytime heating in a nonlinear way, or accelerate it, depending on its timing relative to peak afternoon hours. These events are notoriously difficult for numerical models to capture at 48-hour lead times and could move the actual high two to three degrees from the current model consensus.

Key macro factor: Eastern Mediterranean sea surface temperatures running above the long-term average in summer 2026 weaken the coastal sea breeze, biasing Tel Aviv daily highs toward the upper end of any forecast range.
