Warsaw July 7 High: Will It Hit Nineteen Degrees?

Warsaw’s forecast for July 7 has the market split, and that split tells you something useful. The contract for a peak temperature of exactly 19°C sits at 36% implied probability. That’s not a confident lean either way. It’s a market pricing genuine meteorological uncertainty across a ten-outcome spread.

The market question is simple: what will Warsaw’s highest temperature be on July 7, 2026? The YES contract for 19°C trades at $0.36. The NO side holds at $0.64. The market resolves at noon Warsaw time on July 7. Total volume is $1,962, making this a thin market where a single large position can move the price meaningfully.

How the Warsaw Temperature Contract Works

This contract resolves YES if Warsaw’s official high temperature on July 7 lands exactly at 19°C. Any reading above or below that mark, from 12°C or lower to 22°C or higher, resolves this contract NO. The resolution source is the market’s designated weather data provider.

• YES ($0.36, 36% implied probability): Warsaw’s July 7 high registers exactly 19°C.
• NO ($0.64, 64% implied probability): Warsaw’s July 7 high lands at any other outcome, including 18°C, 20°C, 21°C, or beyond.

The NO side wins whenever the thermometer lands anywhere outside 19°C. That’s a wide target. With ten discrete outcomes on offer, the probability mass is spread across temperatures from 12°C or below all the way to 22°C or higher. A cooler air mass pushing the high to 18°C, or a warmer push to 20°C or 21°C, each independently resolves this contract NO.

Momentum and Market Signals

The contract gained 0.5% in the last hour, with the trend score sitting at 39.80. That’s a mild upward nudge, most likely reflecting updated short-range forecast models converging on 19°C as a plausible central outcome for July 7. The 24-hour change is not available, but the contract moved up roughly 6.5 percentage points from its opening price earlier on July 5, signaling some fresh conviction from early traders.

Volume stands at $1,962 over 24 hours, which is the entirety of this market’s trading history. Liquidity reads at $39,961, meaning the order book is relatively deep compared to what has actually traded. Still, total volume below $2,000 means this market can shift sharply on a single motivated bet. The thin order book is a feature here, not a footnote.

• The 1-hour price change of +0.5% points to mild upward pressure, likely tied to model updates published on July 5.
• The 24-hour context is limited since the market appears to have opened on July 5, making the full trading window less than two days.
• Liquidity of $39,961 against $1,962 in volume signals a market with room for large moves if forecast certainty shifts.
• Trader sentiment leans bearish at 64% NO, consistent with the structural difficulty of hitting exactly one temperature bucket.
• The trend score of 39.80 sits in mild-positive territory but well below levels that would signal strong directional conviction.

Lines Analysis: Warsaw’s July Forecast and What It Means Here

The 36% probability for 19°C reflects where the forecast models cluster, not a coin flip. For central Europe in early July, daily highs in Warsaw typically range between 18°C and 24°C, depending heavily on synoptic flow. If a mild Atlantic system is pressing in for July 7, temperatures in the 17-to-21 range become the likely spread. A 19°C outcome fits the cooler end of a typical early-July day in Warsaw, consistent with partial cloud cover or a northwest flow keeping temperatures suppressed.

The NO case is genuinely strong here, but not because 19°C is unlikely. It’s strong because eight other outcome buckets are each absorbing probability mass. A warmer ridge pushing the high to 21°C or 22°C would resolve NO just as definitively as a cold front holding the high at 17°C. The spread is the risk. Any single forecast error of plus or minus one degree shifts payout entirely.

• European Centre for Medium-Range Weather Forecasts model output for July 7 in Warsaw, if it shifts toward 20°C or above, would reprice the 19°C contract downward fast.
• A strengthening high-pressure system over central Europe between now and July 7 would push probability toward the warmer outcome buckets (21°C, 22°C or higher).
• A cooler Atlantic trough arriving July 6 or 7 would shift mass toward 17°C or 18°C, reducing the 19°C contract’s value.
• Any significant model agreement on a specific temperature by July 6 evening would be the clearest repricing signal in this market.
• The 48-hour forecast window closing on July 6 is the key data event. Short-range models at that range have the highest skill for single-day high temperature forecasts.

The $1,962 in total volume is too thin to draw strong conclusions about collective trader belief. The 36% price likely reflects early positioning by a small number of traders using July forecast data. The market is pricing genuine meteorological uncertainty across a discrete spread. The data right now mildly favors 19°C as a plausible central outcome, but probability is fragmented across the other nine buckets.

LINES VERDICT

Marginal Edge, Fragmented Field

The 19°C contract holds the highest single-bucket probability in a ten-outcome spread, but leading a fragmented field at 36% is not the same as being favored. The market is pricing uncertainty correctly here.

What the market says: At 36% implied probability, the market rates 19°C as the most likely single outcome but gives it less than two-in-five odds. With two days until resolution and a thin $1,962 in volume, this price can move sharply on any updated forecast model run.

Key unknown: The July 6 short-range forecast update from European numerical weather models is the single most important data point. If model consensus shifts one degree warmer or cooler, the 19°C contract reprices immediately.

Scientific Context: July Temperatures in Warsaw

Warsaw’s average July high temperature sits around 24°C to 25°C in recent climatological records, with significant day-to-day variability tied to Atlantic air masses and Central European blocking patterns. A reading of 19°C on July 7 would represent a notably cooler-than-average day, consistent with a persistent northwest flow or a passing frontal boundary. That’s not rare for Warsaw in early July, but it’s not the median outcome either. The gap between the climatological average and the 19°C target is what makes the NO side structurally credible, even before considering the multiple competing outcome buckets.
