Houston High Temp June 11: Can 90-91°F Hold at 51%?

Houston bakes in June. The question for June 11 is whether the mercury peaks in the 90-91°F band or gets pushed higher by the Gulf humidity and heat that define early summer in Harris County. The 90-91°F outcome sits at 51% implied probability. That’s a coin flip with a slight lean, and the market is essentially saying the forecast is too close to call with confidence.

The market question asks: what is the highest temperature in Houston on June 11? The 90-91°F band is priced at $0.51 YES and $0.49 NO, resolving on June 11, 2026 at noon. Total volume stands at $10,452, all of it traded in the last 24 hours. This is a brand-new market with no prior price history to lean on.

How the 90-91°F Contract Works

A YES on this contract pays out if Houston’s verified high temperature on June 11 falls between 90°F and 91°F, inclusive. The resolution body is the market operator, which uses official weather station data for Houston. If the high lands at 89°F or 92°F, this contract resolves NO regardless of how close the forecast was.

• YES ($0.51, ~51%): Houston’s June 11 high temperature falls between 90°F and 91°F.
• NO ($0.49, ~49%): Houston’s June 11 high temperature lands outside the 90-91°F range, in any direction.

The NO outcome is broad. Every competing band, from 79°F or below all the way up to 98°F or higher, contributes to the NO probability. Houston’s June average high sits around 92-93°F. A day that runs even slightly hotter than average knocks this contract to NO immediately. So does a cloudy or stormy afternoon that caps the high at 88-89°F. The 90-91°F band is essentially betting on a mild, slightly below-average June day.

Momentum and Market Signals

The momentum composite here is flat. The 1-hour price change is 0.0%, the trend score sits at 49.60, and 24-hour change data is unavailable since this market only opened today. That flat signal reflects a market digesting early forecast data without a strong directional conviction. The most likely driver of any price shift in the next 12-18 hours is updated National Weather Service forecast model runs for the Houston metro area.

Total volume is $10,452, with all of it coming in the 24-hour window since market open. Liquidity is $40,031, which is healthy relative to volume for a short-duration weather market. That liquidity cushion means a single large bet won’t swing prices wildly. But with total volume under $1 million, any significant weather update or forecast revision can move this contract sharply before resolution.

• The 1-hour price change of 0.0% and a trend score below 50 indicate no directional momentum as of June 10.
• The 24-hour volume matching total volume confirms this market launched today, with no baseline price history to compare.
• The 90-91°F band is competing against ten other outcome options, fragmenting probability across a wide temperature spectrum.
• Houston’s June climatological average high near 92-93°F puts the 90-91°F band slightly below the typical range for this time of year.
• Liquidity at $40,031 versus volume at $10,452 suggests market makers have positioned ahead of forecast updates.

Lines Analysis: Houston Temperature on June 11

The National Weather Service forecast for Houston on June 11 is the single input that matters most here. If model consensus shows a high near 90-91°F, that 51% price is defensible. Houston sees its highs suppressed when cloud cover lingers from overnight convection or when a weak front keeps afternoon temperatures from climbing into the low-to-mid 90s. June 11 falling on a slightly cooler-than-average day is plausible but not the base case for Houston in peak summer.

The broader NO case is strong by construction. Ten competing bands collectively hold 49% of the probability. Houston’s climatological tendency to run at 92°F or above in June means the 92-93°F band alone likely absorbs a meaningful share of that remaining probability. A day that runs hot, which is more common than not in June, pushes the high out of the 90-91°F window entirely. An afternoon thunderstorm could cap the high lower, sending it to 88-89°F instead.

• The National Weather Service Houston-Galveston forecast office publishes hourly model updates. Any shift toward 92°F or above reprices this contract lower.
• Afternoon convective activity on June 11 could suppress the high to 88-89°F, also resolving this contract NO.
• Overnight low temperatures on June 10-11 set the baseline. A warm overnight means a higher daytime ceiling.
• The Gulf moisture feed into the Houston area is the key meteorological variable. More moisture typically means higher humidity but not always higher temperature.
• Any NWS forecast advisory or heat statement issued before resolution would signal a probable NO outcome for the 90-91°F band.

The $10,452 in total volume reflects genuine market uncertainty about where June 11 lands. The data slightly favors the 90-91°F band at 51%, but Houston’s summer climatology runs warmer. The 92-93°F band and the broader heat scenario represent the more historically typical outcome for this date.

LINES VERDICT

NARROW LEAN YES, HIGH UNCERTAINTY

The 90-91°F band holds a slight edge at 51%, but Houston’s June climatology tilts warmer. The next NWS forecast update is the only thing that matters before this resolves.

What the market says: At 51% implied probability, the market is pricing genuine uncertainty, not a directional conviction. With resolution in under 24 hours, any forecast model shift will move this contract fast.

Key unknown: The National Weather Service Houston-Galveston evening model run on June 10 will either confirm or challenge the 90-91°F band. A forecast consensus at 91°F supports YES. Anything at 92°F or above likely drives the price below 40%.

Scientific Context: Houston June Temperature Patterns

Houston’s June climatological average high temperature runs near 92-93°F, based on long-term National Weather Service records for Houston Hobby and Bush Intercontinental airports. Days landing in the 90-91°F range represent a slightly below-average June outcome. That doesn’t make it rare. Cool frontal passages, cloud cover from overnight storms, and strong onshore flow can all hold Houston’s high below 92°F. But the base rate for a June day ending in the 90-91°F band is lower than the base rate for a day ending at 92°F or above. The market at 51% is arguably generous to the 90-91°F outcome given that climatological context. What would move this contract before resolution is simple: a National Weather Service forecast update showing confidence in a 90-91°F high, or evidence of afternoon storm activity that would cap temperatures before the daily maximum is reached.

What is the 51% probability actually saying?

A 51% implied probability means the market sees this outcome as a slight favorite but nowhere near certain. One updated forecast can flip it.

What does a NO resolution mean here?

NO pays out if Houston’s June 11 high temperature lands anywhere outside 90-91°F. That includes both hotter and cooler outcomes across ten competing bands.

What data would move this market most?

A National Weather Service forecast update placing the Houston high at 92°F or above would likely push this contract below 40% quickly. A storm advisory could push it the other direction.

When does this market resolve?

Resolution is June 11, 2026 at noon. Given that Houston’s daily high typically occurs in the early-to-mid afternoon, the resolution may use the high recorded up to that time or the full-day maximum, depending on the operator’s methodology.

Is the volume reliable for this market?

Total volume is $10,452 with liquidity at $40,031. Volume is well below $1 million, meaning a single mid-size bet can move prices meaningfully before resolution.
