What This Dew Point Means in Houston
Whatever the reading above says, the interpretation is the same everywhere. Below 55°F you can go at full effort outdoors. Between 55°F and 65°F it is pleasant to slightly sticky. From 65°F to 70°F most people feel genuinely uncomfortable and outdoor workouts get harder. Above 70°F, sweat stops cooling you efficiently — move exercise to early morning and take heat safety seriously.
Dew Point in Houston — Frequently Asked Questions
What's the highest dew point ever in Houston?
The highest value in Houston's 1995–2024 reanalysis record is 82°F, reached on August 11, 2017. That is the same 30-year window the monthly table above uses — not an official observing-station record, which is a different and shorter dataset. A typical July peak reaches about 75°F, so the all-time mark sits roughly 7°F above a normal summer high.
Is Houston humid or dry?
Humid for most of the year — Houston is one of the most humid major cities in the United States. The median dew point sits in the sticky range from April through October, peaking at 74°F in both July and August, and only November through March falls back below 60°F. Even in its driest months the air is mild rather than crisp: December 47°F, January 44°F, February 49°F. That is roughly a seven-month humid season, about twice as long as Chicago's or New York's — and the reason the monthly table above never shows a truly dry month.
Is Galveston as humid as Houston?
The two cities share the same air mass, so their sticky days line up closely — when Houston turns muggy, Galveston usually does within hours. Galveston's position right on the Gulf makes it slightly more humid on average, and its swings are smaller, because the water keeps coastal dew points steadier than inland. The table above shows the current readings side by side.
What is a comfortable dew point in Houston?
The comfort scale is the same everywhere: a dew point between 50°F and 60°F (10–16°C) feels comfortable to most people in Houston, 60–65°F starts to feel sticky, and anything above 70°F feels oppressive. Local climate changes how often you see each range, not how it feels.
How often does the Houston dew point update?
The reading on this page refreshes every 30 minutes from Open-Meteo, and the timestamp shown is Houston local time. Dew point moves slowly compared with air temperature, so a recent reading is reliable for planning the next few hours.
Why is dew point better than the humidity percentage?
Relative humidity changes meaning with the temperature — 50% is dry on a cool morning and oppressive on a hot afternoon. Dew point is absolute, so 65°F always represents the same amount of moisture and the same sticky feeling.
