Estimated water temperature by month
This is East Los Angeles's typical-year water curve: the same EWMA model as the live widget, run on the 1991–2020 normals instead of this week's weather.
| Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 58° | 59° | 60° | 62° | 65° | 68° | 72° | 74° | 75° | 71° | 66° | 60° |
The curve peaks near 75°F — comfortable-water months here usually involve a heater or a solar cover.
Every station tells its own story: compare this curve with Dublin's pool season and Eastvale's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the California season index.
