Summary: Latitude vs.Wind Speed

Absolutely No Correlation

Since there is no correlation, let's discuss something more interesting: temperature, max temperature, and min temperature. Max temperature is NOT the maximum temperature for the day. The same applies to min temperature. Those two temperatures are answering the question, "At this particular moment, what is the maximum (or minumum) temperature for that location?"

You might be thinking, shouldn't they all be the same? The answer, of course, is no. Many coastal cities with hilly basins are subject a condition called microclimates. San Francisco is a prime example of this occurring. Mark Twain never said it, but there is a quote that states, "The coldest winter I ever spent was a summer in San Francisco." On a typical Wednesday in June at 3PM, depending on where you were at in the city, the temperature you would feel could wildly vary.

• You could be at Oracle Park in China Basin enjoying a Giants game during the day. It's sunny, 80 degrees.
• You could be in Glen Park shielded by straight line coastal winds from Mount Davidson, but experience a temperature in the 60s.
• Or you could be visiting the Sutro Bath ruins on the Pacific Coast. Temperature there? 52 degrees.

On this day at this time, you might see the following conditions reported if you pulled San Francisco's data:

• Temperature - 64 degrees
• Maximum Temperature - 80 degrees
• Minimum Temperature - 52 degrees
