Seattle climate & vial handling
Mild transit climate. August highs average 77°F and February lows 36°F, with a 2016–2025 range of 14°F to 100°F.
Heat days are rare in Seattle (about 0.2 a year at 95°F+), but the 10-year high reached 100°F, so a heat-wave week is still worth timing around.
Freezes are occasional (22.3 nights a year at 32°F or below), so cold matters only for a box left out overnight in February.
Bacteriostatic water such as Hospira's 0.9% benzyl alcohol vials lets you draw a mixed vial more than once; store the sealed water at room temperature and refrigerate after mixing.
Climate: ERA5 reanalysis via Open-Meteo archive API, daily 2 m temperature, 2016-01-01 to 2025-12-31. Hottest month August, coldest February.

Seattle research context
Seattle's research base includes Fred Hutch and the University of Washington, part of a Washington life-sciences footprint that spans Fred Hutch, the University of Washington and the South Lake Union biotech cluster. For a lab here, the practical question is less who is nearby and more how a box behaves over 4 days on a UPS truck in Seattle's weather.
Mild transit climate: August highs average 77°F and February lows 36°F, with a 2016–2025 range of 14°F to 100°F. Cold-chain packaging is not needed for dry lyophilized vials, but timing delivery to avoid a porch or mailbox at the extremes is.
