When factoring in humidity (the Heat Index), the National Weather Service in Albany typically issues Heat Advisories when the heat index is expected to reach 95°F to 99°F for at least two consecutive hours. On average, the capital region experiences about 3 to 5 days per year where humidity pushes the feels-like temperature into this truly oppressive category.

In Albany, dew points above 70°F (21°C) are considered oppressive, while anything above 72°F to 74°F represents tropical, extreme humidity for the Capital Region. The most notable periods of prolonged, high dew points in Albany include:

August 11–13, 2021 (The Stickiest Recent Stretch) – While 2021 had very few 90-degree days, it hosted one of the most humid tropical airmasses in recent history.

• Peak Dew Point: 73.0°F on August 11 and August 13.
• Impact: Humidity reached 97% to 100%, preventing any overnight cooling and creating dangerously high heat indices despite lower air temperatures.

July 5–10, 2024 (Embedded in the 35-Day Heat Streak) – During the 35-day stretch of 80°F+ weather last summer, a massive plume of moisture settled over upstate New York.

• Peak Dew Point: 72.0°F sustained over multiple days (specifically peaking on July 5 and July 10).
• Impact: This period triggered widespread National Weather Service Heat Advisories due to heat index values surging well past 95°F.

August 11–13, 2016 (The Muggy August Spike) – This three-day window saw a severe spike in tropical moisture right in the middle of August.

• Peak Dew Point: 73.0°F on August 13.
• Impact: Maximum relative humidity spiked to 97%, causing dense, heavy air that lingered even through the late-night hours.

August 1, 2006 (The All-Time Recent Record) – The highest single-day dew point recorded at the main climate station in the last two decades occurred during a severe early-August heatwave.

• Peak Dew Point: 73.9°F on August 1, 2006.
• Impact: This combined with an air temperature of 94°F to create the most oppressive heat index of the mid-2000s.
