Utah · US States · Trend-based projections to 2050
This page uses Salt Lake City's own 50 year weather record to project one trend line forward to 2030, 2040 and 2050, with a Best and Worst scenario range built from the trend's own statistical uncertainty. For where that trend has already gone, see the Climate Capitals Trends, or for current and historical day-to-day weather, see Meteo Capital Cities.

Frequently asked questions about Salt Lake City's projected trends
How warm will Salt Lake City be in 2050?
Extrapolated from Salt Lake City's own record since 1976, the average daytime high in 2050 works out at roughly 18.7°C, down 0.3°C from 2025. This is a straight-line projection of measured weather data, not a climate model or a scenario-based forecast.
How certain is the temperature projection for Salt Lake City?
The 2050 range runs from 17.8°C to 19.5°C. That spread comes from the 95% confidence interval on the trend line's own slope, so the noisier Salt Lake City's record, the wider the band. The trend accounts for 36% of the variation between years; the rest is ordinary year-to-year swing.
How many days above 30°C will Salt Lake City get in 2050?
The trend line lands on roughly 97 days above 30°C a year in 2050, against 86 in 2025. These are the days that set peak cooling demand, so this figure matters more for grid planning and building design than the annual average above.
Will Salt Lake City still get frost in 2050?
The trend line lands on roughly 117 frost days a year in 2050, against 99 in 2025. Fewer frost days sounds pleasant, but it also shortens the natural cold period plants and pest control rely on.
Is Salt Lake City getting wetter or drier by 2050?
The trend line lands on roughly 458mm of precipitation a year in 2050, against 644mm in 2025, so drier. An annual total says little about distribution though: the same rainfall can arrive in shorter, harder bursts, and that is what loads drains and water storage.
Will Salt Lake City get more sunshine by 2050?
The trend line lands on roughly 3755 sunshine hours a year in 2050, against 3774 in 2025, so less sun. Sunshine hours bear directly on rooftop solar yield, though heat works against it at the same time: a panel loses efficiency at high temperatures.
