Hotter still is the core. In the sun this is thought to be 10 - 20 million degrees. These temperatures are due to the pressure caused by gravity trying to compress the star. It has to be this temperature for fusion of hydrogen to take place.
In most years, Seattle averages a daily maximum temperature for September that's between 69 and 73 degrees Fahrenheit (20 to 23 degrees Celsius). The minimum temperature usually falls between 52 and 55 Â°F (11 to 13 Â°C).
High temperatures in July average about 75 F (24 C), while low temperatures in winter drop below freezing an average of only 15 days per year. Seattle averages 158 days of measurable rain and 226 days of some cloud cover per year. Both most often occur in the winter and during the night. Seattle is in the direct path of the highly unstable Puget Sound Convergence Zone which makes local weather forecasting as much an art as a science.
