**Forecast models and NWS guidance indicate Houston highs on June 20 will likely fall in the upper 80s to low 90s°F, reflecting persistent subtropical high pressure, Gulf moisture, and typical early-summer heating.** Trader consensus clusters around 86–91°F because ensemble spreads show uncertainty in afternoon cloud cover and scattered convection, which can reduce peak temperatures by 2–4°F through reduced insolation. Sea-breeze circulation and variable low-level winds further modulate boundary-layer mixing, while any weak frontal remnant or increased tropical moisture could enhance shower chances and cap the maximum. Historical June normals near 92°F provide context, yet recent pattern shifts with elevated humidity and heat indices near 107–114°F underscore how small forecast adjustments in precipitation timing or thickness can shift outcomes between the tightly bunched 88–89°F and 90–91°F bins. Updated model runs and afternoon observations will refine these probabilities ahead of resolution.

This market will resolve to the temperature range that contains the highest temperature recorded at the William P. Hobby Airport Station in degrees Fahrenheit on 20 Jun '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the William P. Hobby Airport Station, available here: https://www.wunderground.com/history/daily/us/tx/houston/KHOU.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
The resolution source for this market measures temperatures to whole degrees Fahrenheit (eg, 21°F). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.**Forecast models and NWS guidance indicate Houston highs on June 20 will likely fall in the upper 80s to low 90s°F, reflecting persistent subtropical high pressure, Gulf moisture, and typical early-summer heating.** Trader consensus clusters around 86–91°F because ensemble spreads show uncertainty in afternoon cloud cover and scattered convection, which can reduce peak temperatures by 2–4°F through reduced insolation. Sea-breeze circulation and variable low-level winds further modulate boundary-layer mixing, while any weak frontal remnant or increased tropical moisture could enhance shower chances and cap the maximum. Historical June normals near 92°F provide context, yet recent pattern shifts with elevated humidity and heat indices near 107–114°F underscore how small forecast adjustments in precipitation timing or thickness can shift outcomes between the tightly bunched 88–89°F and 90–91°F bins. Updated model runs and afternoon observations will refine these probabilities ahead of resolution.
