Fire weather
Fire weather across Siskiyou County
Fire-weather scores are measured across Siskiyou County and sit in a narrow band: 52.4 near Happy Camp, 55.5 near McCloud, and 54.4 at the middle.
Because that weather range is tight compared with other factors, place-to-place differences in overall wildfire risk are more associated with terrain, fuels, hazard-zone patterns, and fire history than with large swings in fire-weather score.

Independently of Satelife's layers, the USFS Wildfire Risk to Communities grid puts the county's mean annual burn probability at 1.44% (90th percentile cell: 3.47%), with a mean conditional flame length of 7.28 ft. 97% of the 30,715 grid cells inside the county carry burnable fuel at all.

CAL FIRE has no mapped Fire Hazard Severity Zone at 92 of the 162 sampled points — the zones cover Local Responsibility Areas, and most of this county is state or federal land. At 92 of them the USFS grid above supplied the hazard reading instead.
162 sample points on a ~2.3 km grid, plus one at the centre of each community, weighted with the Satelife county profile v1 · median layer coverage 100%. Scores are 0–100 and comparable within the county, not across states.
For a property
What a county range means for one address
For county-wide context, FEMA’s National Risk Index rates Siskiyou County’s wildfire risk as Relatively High, and its wildfire expected annual loss as Relatively High.
In the USFS Wildfire Risk to Communities model, mean annual burn probability is 1.44%, and the 90th-percentile cell is 3.47%. It also indicates 97.3% of the county is in burnable area.
The same USFS model reports a mean conditional flame length of 7.28 feet, which contributes to how intense fire behavior may be where burning occurs.
Across 162 sampled points in Siskiyou County, the score runs from
27 to 82.1 — two neighbouring parcels can sit in different tiers.
A county number is the middle of that spread; it says nothing about which end yours is at.
