Hardwood Decking in Salt Lake City, UT

Building a Deck in Salt Lake City, UT: Local Conditions

Salt Lake City, UT runs from roughly 23°F in winter to 93°F in summer, with about 16" of rain a year and low humidity. At 4,226 feet, thinner air means stronger UV and faster drying than the temperature range implies. Roughly 95 freeze-thaw cycles pass through the deck each year. Salt Lake pairs desert-dry air with a full freeze-thaw winter and hot summers — boards move in both directions each year.

What those numbers mean for your boards

• Summer highs around 93°F with sustained sun load — enough to fade an unoiled surface to gray within two seasons.
• Winter lows near 23°F put every fastener through repeated contraction cycles.
• About 95 freeze-thaw cycles per year. Water that sits in an un-sealed end cut will split it open by the third winter.
• Elevation of 4,226 ft adds UV load and dries boards faster than the numbers alone suggest.
• Wildland-urban interface zone. All six species we carry are Class A fire-rated, which is what local review typically asks for.
