Never thought of Google Books, and somehow never stumbled onto NOAA.<br />Two questions:<br />Some findings indicate nasty rain on April 23, others suggest weather was mild throughout.

I also tried a few area newspaper archives, but couldn't find anything that went farther back than the late 1970s.<br /><br />Finally, I googled "San Francisco Weather April 1906" and arrived at the NOAA site (and thought to myself, "duh!!!") mentioned above: http://www.wrh.noaa.gov/mtr/sfd_sjc_climate/sfd/SFD_CLIMATE3.php<br /><br />Relevant passage:<br /><br />There is a discrepancy in the records (Null, 1978; Pericht 1988) as to whether observations were taken between April 18 and May 1, 1906.

I knew that Wolfram Alpha returns some historical weather data so went there to search for [San Francisco weather April 18, 1906] http://www.wolframalpha.com/input/?i=San+Francisco+weather+April+18%2C+1906 but it doesn’t go back that far. <br /> <br />I then went to Google Books and searched for [San Francisco weather "April 18, 1906"] then tried to narrow to magazines (I thought newspapers were there too but was wrong.) Headed over to Google News and tried [San Francisco newspaper 1906 "april 19"] to find a weather report. Nothing there that struck me as useful. <br /><br />Back to Google to search for [weather history 1906] to try to find a site for historical weather data. Looked at http://www.archives.gov/research/guide-fed-records/groups/027.html#27.6.3<br />Again, I didn’t find anything that gave me what I was looking for. I jumped over to the Library of Congress and searched for [weather san francisco 1906]. I picked one halfway down the page. Microsoft Word - 1December2006TALCover1252007.doc I can’t remember why I chose it but in the document I searched for [earthquake]. I found references to the “newly chartered Red Cross”. <br /><br />At the Red Cross site I searched for [earthquake 1906] and got http://www.redcross.org/portal/site/en/rco_search?q=1906+earthquake&submit=GO<br />I picked a lesson plan for grades k-2 just see what they talked about (I work in an elementary school.) The lesson plan references The Virtual Museum of San Francisco http://www.sfmuseum.org/<br /><br />Searching there for [weather 1906] http://www.sfmuseum.org/searchresults.html?cx=017537146380771376400%3Apkfl8lk2x8k&cof=FORID%3A11&ie=UTF-8&q=weather+1906&sa=Search produces articles, newspaper clippings and eyewitness accounts. <br /><br />From this one http://www.sfmuseum.org/1906/ew20.html I would say it was unusually warm (heat wave) and from this one dated April 24, 1906 http://www.sfmuseum.net/press/clips13.html I would say they also experienced rain within the week following the earthquake.krossbowhttps://www.blogger.com/profile/07877826327758153784noreply@blogger.comtag:blogger.com,1999:blog-4953008377950396317.post-69864162683066906602011-12-21T09:15:29.138-08:002011-12-21T09:15:29.138-08:00PS.
