What's active right now

Summer heat and drought suppress tick questing across most of the West. Unlike the Northeast, midsummer is a LOW point out West: dry air and cured grass push ticks down to rehydrate. The exception is California chaparral, where Pacific Coast tick larvae and nymphs hold a late-summer bite risk.

Local tick habitat

Half Moon Bay is 62% natural land cover (31% forest, plus open and brushy areas) across its 6.24 sq mi, home to about 11,105 people. That makes it the 13th-most wooded of the 30 towns in San Mateo County. The Rocky Mountain wood tick favors shrub-steppe, rocky slopes, and grassland-forest edges, while the western blacklegged tick lives in oak woodland and coastal brush: the more of that habitat a town has, the more places ticks can quest.

San Mateo County reports little or no Lyme disease, which is typical across the West. That does not mean low tick risk: the Rocky Mountain wood tick is what drives risk here, biting in spring and carrying Rocky Mountain spotted fever, Colorado tick fever, and tularemia. Its spring peak, combined with Half Moon Bay's local habitat, sets how high the daily score can climb.
