When you think of Houston, Texas & Honolulu, Hawaii, do balmy temperatures come to mind. ? Both cities have a mean temperature of 750.

However, the mean temperature does not tell the whole story.

The temperature in Houston differs seasonally 0 from a low of about 40 in January to a high of close to 1000 in July and August.

By contrast, Honolulu’s temperature varies less throughout the year, usually ranging between 600 and 900.
