Wind Gusts

Wind gusts, measured as maximum short-duration wind speed peaks at 10 meters height, represent the sudden bursts and lulls that differentiate merely windy conditions from challenging or dangerous photography situations. Unlike sustained wind speed which averages over minutes, gusts last only seconds but deliver forces that shake tripods, blow over equipment, unbalance photographers, and occasionally damage gear.

For photography planning, the relationship between sustained winds and gusts reveals stability: gusty conditions where gusts exceed sustained winds by 50-100% indicate turbulent, unstable atmosphere common ahead of storms and during strong heating, while low gust ratios under 30% suggest smooth, steady winds typical of stable high pressure. Gusts below 5 m/s (18 km/h) rarely cause issues beyond minor tripod vibration during longer exposures. Gusts of 6-10 m/s (20-36 km/h) require attentive tripod setup with ballast or low camera positions, sturdy tripod legs spread wide, and awareness that weaker gusts may still introduce slight vibration in exposures over 1 second. Gusts of 11-15 m/s (40-55 km/h) demand heavy-duty tripods weighted significantly, low shooting positions minimizing wind catchment, and constant vigilance as sudden gusts can shift loose equipment or unbalance photographers during setup.

Gusts above 15 m/s (55+ km/h) push into dangerous territory where equipment blowover becomes likely, physical safety concerns emerge, and most photographers rightly abort shoots rather than risk injury or gear damage. However, these extreme conditions also produce uniquely dramatic photography: massive waves, horizontal rain, violently moving clouds, and storm scenes impossible to capture in calmer weather. PhotoWeather differentiates sustained winds from gusts to help photographers distinguish manageable breezy conditions from turbulent, unstable situations requiring extra precautions. Understanding gust timing through observation helps photographers shoot during brief lulls between gusts, releasing shutters when winds momentarily calm. Gust forecasts also reveal approach of frontal systems: increasing gust speeds ahead of time indicate unstable, turbulent conditions, while steady or decreasing gusts suggest stable weather. For storm photography, target sustained winds of 8-12 m/s with gusts to 18 m/s for manageable drama. For stable long exposures, seek gusts below 4 m/s. For safety margins, add 50% buffer to gust forecasts when planning equipment load limits.
