Coyote movement and calling responsiveness are heavily gated by weather conditions — not just wind speed but barometric pressure, temperature thresholds, moon phase, and humidity all independently affect whether coyotes are on their feet and willing to commit to a stand. A hunter who ignores these variables calls in unpredictable conditions and misattributes failures to technique rather than environment.
A hunter reads multiple weather variables before leaving the truck and makes an explicit go/no-go decision about calling conditions. They know the 66°F threshold: in western states (Utah, Montana, Wyoming, Nevada, Colorado), coyotes move all day when temperatures stay below 66°F; above that, they limit activity and bed in shade until afternoon. In desert-adapted populations (Arizona, New Mexico), the threshold shifts to roughly 72°F. Barometric pressure is tracked directionally: falling pressure (storm incoming, east wind) shuts coyotes down; rising pressure after a front passage turns them back on. Moon phase affects night hunting — full moon activity peaks before moonrise and after moonset; calling mid-full-moon night typically produces blank stands. During multi-day cold fronts, coyotes will eventually "run you over" after 3–5 days of being pinned down. High winds (15+ mph) cut effective calling range dramatically and reduce the number of coyotes called per day roughly in half per 10 mph increment above calm.
East wind means a storm is coming and barometric pressure is falling — the single most suppressive condition for coyote movement. Most hunters check wind for scent management only; experts check wind direction as a real-time barometric proxy when they don't have a barometer. West wind means clearing and rising pressure — go hunt.
