NASA MUR monthly averages, 2016 to 2025. History through Oct 8, 2026.

Read the time first

The buoy number is one point in the lake. Use its time, not the time you opened this page. If the live feed is late, we hide the old number. You can still use the buoy source to read its report.

The month chart uses NASA MUR satellite data. That is not the same sensor as the buoy. The table shows the years used for the mean. Use it as a rough guide to the time of year, not a forecast for your swim spot.

Before a swim

The swim words are our rule of thumb. They are not a test of what is safe for you. NWS warns that cold water can cause shock and loss of strength. Read the NWS cold water guide and the lake forecast before you go.

Questions people ask

What is Lake Tahoe's water temperature today?
Read the buoy number and its time at the top of this page. If the reading is late, the page says Status unknown. The number is one lake reading, not a beach report.
What is Lake Tahoe water temperature by month?
The month table lists the average for each month from our NASA MUR history. It is a surface water record. The years used for the average are shown with the table.
How cold is Lake Tahoe?
The live buoy number shows how cold the water is at that sensor now. The past data gives a wider view. A monthly mean cannot tell you how cold your swim spot is today.
Can you swim in Lake Tahoe today?
A water temperature alone cannot tell you if a swim is safe. Our table uses plain guide words. They are not safety advice. Read the NWS cold water guide and the lake forecast before you go.
Is Lake Tahoe warmer than normal today?
The normal section shows the gap from this month's past average when the buoy data is fresh. The past average is from a satellite record, so it is a rough comparison.
