Lake George Water Temp: What to Expect Before You Dip
Want the latest on Lake George’s water temperature? This guide provides a quick summary of current conditions, monthly averages, and the factors influencing this dynamic lake.
Current Water Temperature: A Quick Look
Real-time Lake George water temperature data from the Lake George Association (LGA) is currently unavailable. The LGA (https://www.lakegeorgeassociation.org/) is the official source for this information, and we’ll update this section as soon as their data feed is restored.
Unofficial estimates suggest the temperature is likely between 61-63°F. However, this is an approximation and should be treated with caution. Always defer to the official LGA readings for accurate information.
Why is the Official Data Unavailable?
Like any technology, real-time data systems can experience occasional outages. The LGA is actively working to restore their sensor and data feed. We encourage you to check back frequently for updates.
Understanding Lake George’s Temperature: Location Matters
Measuring lake temperature isn’t as simple as taking a single reading. Temperature varies across the lake due to factors like water depth, sunlight exposure, and wind currents. Shallow areas near the shore tend to be warmer than deeper sections.
The official LGA sensor, when operational, is located at the Darrin Freshwater Institute (DFWI) dock near Bolton Landing, submerged approximately 1.6 feet below the surface. This placement provides a representative temperature for typical swimming and boating activities. The Jefferson Project (https://www.jeffersonproject.org/) also contributes valuable data, gathering detailed information on various water quality parameters, including temperature at different depths, using sophisticated sensor-equipped buoys.

What Drives Lake George’s Temperature Changes?
Lake George’s temperature is a dynamic interplay of several factors:
Sunlight: The primary driver, directly heating the water’s surface. Cloud cover reduces solar radiation and moderates warming.
Air Temperature: The lake absorbs heat from the surrounding air, so warm air temperatures generally lead to warmer water.
Wind: Increases evaporation, which has a cooling effect. Strong winds can also mix surface and deeper waters, influencing overall temperature distribution.
Groundwater: Influx of groundwater from springs and streams can either cool or warm the lake depending on its temperature relative to the lake water. The southern end of Lake George, receiving more groundwater, experiences more moderate temperature shifts.
Lake Morphology and Topography: The surrounding mountains influence wind patterns and sun exposure, creating microclimates and temperature variations across the lake.
Thermal Stratification (Summer): The lake forms distinct layers based on temperature. Warmer, less dense surface water floats above cooler, denser deep water.
Long-Term Trends: Research suggests a gradual warming trend in Lake George, particularly in the northern basin, possibly linked to climate change. Further study is ongoing to confirm these observations and predict future impacts.
Local Weather Forecasts: These often provide general water temperature estimates.
Marinas and Lakeside Businesses: They often have firsthand knowledge of current water conditions.
The Jefferson Project: (https://www.jeffersonproject.org/) Offers valuable data and visualizations of Lake George’s ecosystem, including temperature information.
