in a 2011 study of SARS-COV-1 (not the current virus, but related) that measured its persistence over time in 28C(82F), 33C(91F), 38C(100F),
the conclusion was

SARS CoV is a stable virus that may potentially be transmitted by indirect contact or fomites, especially in air-conditioned environments....
The dried virus on smooth surfaces retained its viability for over 5 days at temperatures of 22–25°C and relative humidity of 40–50%, that is, typical air-conditioned environments.
However, virus viability was rapidly lost (>3 log10) at higher temperatures and higher relative humidity (e.g., 38°C, and relative humidity of >95%).

To my eyes, the 100F temperature degraded the virus much more rapidly, while the 82F and 91F were very much the same.
Higher humidity degraded the virus more.

So, yes, our cool, dry summers may not hamper this virus.  Air conditioning will be even more conducive to its survival.

SARS-COV-1 is different that SARS-COV-2.  Another report comparing the survival of the two on different surfaces found

Our findings show that the stability of HCoV-19 and SARS-CoV-1 under the experimental 51 circumstances tested is similar.
