Climate & Weather in McLean
McLean shares Northern Virginia's genuine four-season, humid subtropical-to-continental-transition Mid-Atlantic climate -- hot, humid summers and cool-to-cold winters with periodic snow -- the same regional climate framing already established for this project's other NoVA sibling records.

Learn moreA genuine four-season Mid-Atlantic climate
McLean experiences real seasonal variation: hot, humid summers and cool-to-cold winters, consistent with the broader NoVA/Mid-Atlantic pattern documented for this project's Arlington, Ashburn, Fairfax, Tysons, Reston, and Vienna sibling records. Specific NOAA climate-normal average-temperature and snowfall figures were not independently re-verified this session -- disclosed as a research gap rather than invented.
A genuinely wooded, Potomac-adjacent setting for parts of McLean
McLean's western and northern areas run adjacent to the Potomac River and include genuinely wooded parkland (Scott's Run Nature Preserve, the George Washington Memorial Parkway corridor) -- a real, distinctive natural setting contributing to the area's character, alongside the more standard suburban development pattern elsewhere in McLean.
Winter: real snow and ice, without a mountain-town profile
McLean sees real winter snow and ice events, though not the deep, reliable accumulation of Virginia's Blue Ridge/Shenandoah mountain communities documented in this project's Virginia state record.
Remnant tropical-system moisture, not direct hurricane impact
As an inland NoVA market, McLean's most relevant tropical-weather exposure is rainfall from remnant tropical systems (contributing to the flash-flood risk detailed on insurance-hazard-costs) rather than direct hurricane wind or storm surge, which remains a coastal Hampton Roads/Tidewater risk.
