Dew Point in Phoenix — Frequently Asked Questions
What's the highest dew point ever in Phoenix?
The highest value in Phoenix's 1995–2024 reanalysis record is 81°F, reached on July 18, 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. The median August dew point reaches about 58°F, so the all-time mark sits roughly 23°F above a normal summer high.
Is Phoenix more humid or dry?
Dry for most of the year. Phoenix never reaches the sticky range — its highest monthly median is 58°F.
Is Tempe as humid as Phoenix?
The two cities share the same air mass, so their sticky days line up closely — when one turns muggy, the other usually does within a day. The table above shows the current readings side by side.
What is a comfortable dew point in Phoenix?
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 Phoenix, 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 Phoenix dew point update?
The reading on this page refreshes every 30 minutes from Open-Meteo, and the timestamp shown is Phoenix 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.
