How does the temperature feel?
Humidity is an essential factor in how you experience temperature. When a warm period is accompanied by high humidity, it results in a higher perceived temperature. This is especially true when temperatures exceed 25°C, as it can cause greater discomfort.
In Lake Mead, during the coolest month, January, you will experience 44% humidity, which is considered moderate. This is accompanied by an average maximum temperature of 16°C. In the warmest month, July, the humidity is 21% combined with an average maximum temperature of 42°C, which creates a low-feel temperature.

How are these Temperatures Measured?
Generally, temperature data depicting climate is usually given over a 30-year average in order to reduce short-term fluctuations and reveal better long-term trends in climate conditions.
This temperature data is taken from land-based thermometers, ocean buoys, ships, and satellites. These measurements are transmitted to weather stations and climate centers around the globe where they are processed, averaged, and analyzed in order to monitor the trends and create climate models.
Temperatures in the Mountains
Although not all regions have mountains, elevated areas exhibit distinct temperature variations.
- Sun Exposure: Sunlit slopes tend to be warmer, while shaded areas remain cooler.
- Altitude Effects: Temperatures drop by approximately 6°C for every 1,000 meters of elevation, creating distinct microclimates.
