Climate & Weather in Meridian

Meridian has a genuine high-desert, four-season climate -- hot, dry summers (July average high 91°F) and cold winters with real, if modest, snowfall (roughly 14.45 inches across 27 snowy days annually) -- at a real, disclosed elevation of approximately 2,600 feet, meaningfully lower and milder than Idaho Falls' higher-elevation, more severe winter climate built as a distinct Eastern Idaho market elsewhere in this project.

A Genuine High-Desert Four-Season Climate

Meridian's climate produces real, distinct seasons rather than the narrow, mild year-round range built for Seattle elsewhere in this dataset: hot, dry summers (July average high 91°F, low 59°F) and cold winters (December average high 39°F, low 24°F), with an annual temperature range of roughly 23°F to 92°F -- a genuinely different profile that rewards residents who want real seasonal change without the severity of a higher-elevation Mountain West winter.

Low Humidity Is a Real, Defining Feature

As a genuine high-desert climate, Meridian carries real, low humidity year-round -- a meaningful comfort factor during summer's hot afternoons (heat feels drier and, for many people, more tolerable than in a humid climate at the same temperature) and a real consideration for anyone moving from a humid-subtropical or marine climate built elsewhere in this project.

Winter Snowfall Is Real But Modest Relative to Idaho Falls

Meridian receives real, if modest, winter snowfall -- approximately 14.45 inches across roughly 27 snowy days per year -- meaningfully less than Idaho Falls' 41 inches of annual snowfall built as a genuinely distinct, higher-elevation Eastern Idaho market elsewhere in this same pass. This is a real, disclosed, and deliberate differentiation this record makes rather than applying one uniform 'Idaho winter' framing across genuinely distinct regions.

Annual Rainfall Runs Genuinely Low

Meridian averages just 11 inches of annual rainfall -- a genuinely arid, high-desert figure distinct from both Seattle's 37.49-inch marine climate and more humid regions covered elsewhere in this project, reflecting the Treasure Valley's real, historic dependence on irrigation for its agricultural heritage and continued landscaping needs.

Regional Wildfire Smoke Is a Real, Secondary, Late-Summer Consideration

As detailed on the flood-hurricane-risk topic page, regional wildfire smoke from surrounding Idaho, Oregon, and Nevada fires can drift into the Treasure Valley during some late-summer periods -- a real, if intermittent, air-quality factor worth knowing, though a specific current frequency figure was not confirmed this pass.
