<p>After taking some time to explore how the weather in North Carolina stacked up over the past years, I was interested in doing the same analysis for other cities. Growing up with family from Binghamton, NY I was always told it was very cloudy there. And Seattle has a nasty reputation for being very depressing and cloudy. All said, the cities I want to examine are:</p>
<ul>
<li>Binghamton, NY</li>
<li>Cary, NC</li>
<li>Seattle, WA</li>
<li>New York City, NY</li>
</ul>
<p>I'd be interested to try this analysis worldwide at some point - comparing London and Seattle might be an interesting analysis. For now though, we'll stick with trying out the US data.</p>
<p>There will be plenty of charts. I want to know: <strong>How has average cloud cover and precipitation chance changed over the years for each city mentioned?</strong> This will hopefully tell us whether Seattle has actually earned its reputation for being a depressing city.</p>

<p>Well, as it so happens it looks like there are some data issues. July's data is a bit sporadic, and 2013 seems to be missing from most months as well. I think really only two things can really be confirmed here:</p>
<ul>
<li>Seattle, specifically for the months of October and November, is in fact significantly more cloudy on average than are other cities</li>
<li>All cities surveyed have seen average cloud cover decline over the months studied. There are data issues, but the trend seems clear.</li>
</ul>
<p>Let's now move from cloud cover data to looking at average rainfall chance.</p>

<p>The same data issue caveats apply here: 2013 seems to be missing some data, and July has some issues as well. However, this seems to confirm the trends we saw with cloud cover:</p>
<ul>
<li>Seattle, specifically for the months of August, October, and November has had a consistently higher chance of rain than other cities surveyed.</li>
<li>Average precipitation chance, just like average cloud cover, has been trending down over time.</li>
</ul>
<h2 class="anchor anchorWithStickyNavbar_LWe7" id=conclusion>Conclusion<a href=#conclusion class=hash-link aria-label="Direct link to Conclusion" title="Direct link to Conclusion"></a></h2>
<p>I have to admit I was a bit surprised after doing this analysis. Seattle showed a higher average cloud cover and average precipitation chance than did the other cities surveyed. Maybe Seattle is actually an objectively more depressing city to live in.</p>
<p>Well that's all for weather data at the moment. It's been a great experiment, but I think this is about as far as I'll be able to get with weather data without some domain knowledge.
