Houston July 5 High Temp: Will 94-95°F Hold?

Houston sits at the edge of a classic Gulf Coast summer setup on July 4. The 94-95°F band carries a 38.5% implied probability heading into tomorrow’s peak heat window. That is a plurality lead in a ten-way market, but a fragile one. The spread is genuinely competitive, and traders leaning bearish on this band have pushed the NO price to $0.62.

The market question asks which two-degree range will capture Houston’s highest temperature on July 5. Resolution is set for July 5 at noon Central. At current prices, YES costs $0.39 and NO costs $0.62. Total volume stands at $7,494, all of it arriving in the last 24 hours. This market opened today and drew immediate action.

How the 94-95°F Contract Works

YES resolves profitable if Houston’s official high temperature on July 5 falls strictly between 94°F and 95°F inclusive. NO resolves profitable if the official high lands anywhere outside that band, including lower ranges like 92-93°F or higher ranges like 96-97°F and above. A single competing outcome capturing the actual high is enough for NO to win.

• YES ($0.39, 38.5% implied): Houston’s July 5 high lands in the 94-95°F window.
• NO ($0.62, 61.5% implied): Houston’s July 5 high falls outside that range in either direction.

The NO side wins across nine other outcomes. Houston’s July 4 pattern matters here. The city recorded highs in the mid-to-upper 90s on multiple July 4 dates over the past decade, with heat index values regularly pushing past 100°F when Gulf moisture is present. A pattern of high dew points and persistent southerly flow tends to push actual air temperatures above 95°F, which would shift value to the 96-97°F or 98-99°F bands instead.

Momentum and Market Signals

The 1-hour momentum is flat at 0.0%, and the trend score sits near neutral at 50.60. The modest intraday price lift of roughly 6% from the market open reflects early positioning, not a strong directional conviction. Here’s what the measurements are telling us: traders are treating the mid-90s as the most likely single outcome without yet committing heavily to it.

Total volume is $7,494, with all of it arriving in the 24-hour window since the market launched. Liquidity is notably deeper at $50,162, which means the order book can absorb movement without major slippage. Still, at under $10,000 in total volume, this is a thin market. A single large trade or a midday weather model update could reprice the contract sharply before resolution.

• The 1-hour price change is flat, and the 24-hour trend is mildly bullish from the open, both pointing to cautious early positioning rather than conviction.
• Liquidity at $50,162 is healthy relative to volume, meaning the spread reflects genuine uncertainty rather than a thin-book distortion.
• The 94-95°F band holds the plurality implied probability at 38.5%, but the 61.5% NO price reflects real competition from adjacent temperature bands.
• Related science markets show strong activity, suggesting an engaged trader base on weather and climate contracts today.
• Volume below $1,000,000 means this price can move sharply if a weather update or model run shifts the consensus high-temperature forecast.

Lines Analysis: Houston Heat on July 5

The National Weather Service Houston office is the relevant agency for official temperature readings. NWS Houston uses its primary observing station at George Bush Intercontinental Airport (KIAH) as the standard high-temperature record for the city. July 5 falls inside Houston’s hottest climatological stretch, when daytime highs average in the mid-90s and upper-level high pressure frequently suppresses cloud development. A surface high centered over the region would produce a dry, sunny afternoon that pushes the high toward or above 96°F.

The 94-95°F range loses when Gulf moisture surges before peak heating, which can paradoxically cap air temperatures by increasing cloud cover and afternoon convection. It also loses when the upper-level ridge strengthens enough to produce a drier, hotter profile in the 97-100°F range. The data doesn’t care about the politics: both failure modes are meteorologically plausible on any given July day in Houston.

• NWS Houston’s afternoon forecast for July 5 is the single most important input. Any model output showing a high above 96°F or below 93°F directly reprices adjacent bands.
• Dew point readings at KIAH on the morning of July 5 signal moisture load. Dew points above 75°F typically suppress the air temperature peak but raise heat index values.
• Upper-level ridge position over Texas determines whether afternoon temperatures peak in the lower, middle, or upper portion of the 90s range.
• Afternoon cloud cover or storm development before 4 p.m. Central would cap the high and push probability toward the 92-93°F band.
• Any National Weather Service excessive heat advisory issued for Harris County before resolution would signal a higher-temperature outcome is favored.

The market is pricing uncertainty, not science. With $7,494 in total volume across a ten-way market, the 94-95°F band’s 38.5% share is consistent with it being the climatological mode for a Houston July day, but the distribution is wide. Adjacent bands at 96-97°F and 92-93°F each carry meaningful probability. The data marginally favors the higher end of the spectrum given the July 4 holiday heat pattern and typical ridge placement this time of year.

LINES VERDICT

NARROW PLURALITY, WIDE UNCERTAINTY

The 94-95°F band is the single most likely outcome, but it is not the probable outcome. In a ten-way temperature market, plurality does not equal confidence, and the weather pattern on July 5 has multiple plausible paths.

What the market says: At 38.5% implied probability, the market prices 94-95°F as the mode of a genuinely uncertain distribution. Thin volume means this price is particularly sensitive to any updated NWS forecast before the July 5 noon resolution.

Key unknown: The National Weather Service Houston afternoon forecast for July 5 is the decisive input. A projected high of 96°F or above shifts value to adjacent bands; a forecast of 93°F or below does the same in the opposite direction.
