Water Temperature History
Historical averages are calculated from USGS Landsat satellite-derived surface-temperature observations. They are not current lake-temperature readings.
About this data
Each month’s historical average gives every observed year equal weight. It is not a formal climate normal.
A month appears only when at least three different years were observed. Missing months stay blank.
Satellite observations currently end in March 2026.
The 2022 and 2023 archives have not been processed, so those years are not confirmed gaps.
This is historical satellite context for Lake Eustis. It is not the current water temperature.
When recent water-temperature readings exist, each orange point is that week’s average. Weeks without a reading stay blank.

Source: USGS Landsat 8 — Satellite-derived surface temperature. Satellite observations currently end in March 2026. A blank month does not have three observed years and was not estimated.
Typical Water Temperature
Each month is the equal-weight average of USGS Landsat surface temperatures from years with at least three observations. The archive ends March 2026. A blank month was not estimated.

Temperature and fishing
Water temperature changes how active fish are and where they hold. This page is the temperature record for Lake Eustis. The fishing outlook uses weather, solunar timing, and lake conditions, and it is a separate forecast.

The latest reading’s source is on the current temperature card. Monthly averages are USGS Landsat 8 — Satellite-derived surface temperature. Each observed year has equal weight, and a month is published only after three years. The archive ends March 2026.
