+### Seasonal fuels
+
+LANDFIRE Seasonal Fuels adjusts FBFM40 for a time of year — early spring
+(`"ES"`), spring (`"SP"`), summer (`"SU"`), or fall (`"FA"`). Pass `season`
+together with a seasonal `version` (`"2025"`) to fetch it on demand from the
+LANDFIRE Product Service instead of the staged annual release:
+
+```python
+grid = ff.grids.create_fuel_model_grid_from_landfire_fbfm40(
+    domain, version="2025", season="SP", output_resolution_m=30
+)
+```
+
+`grid.represented_year` is the projected season year — version `"2025"` plus
+`"SP"` is spring 2026:
+
+```python
+>>> grid.represented_year
+2026
+```
+
+!!! warning "Seasonal coverage is limited"
+
+    Seasonal Fuels covers a changing region rather than all of CONUS. A
+    request for a domain outside the current coverage raises
+    `UnprocessableEntityException`. See
+    [LANDFIRE Seasonal Fuels](https://landfire.gov/fuel/seasonal_fuels) for
+    current availability.

 ### Look up fuel parameters from FBFM40 codes
 
 The `fbfm` band holds codes, not the quantities a fire model consumes. To
