That August, it rained more than 17 inches in Boston--still the record. According to news reports, this caused a rat problem in the city. At least the Sox were 47-31 at Fenway.



Average rainfall: 5.0 inches/month

Average high temperature: 78.6° F

Win-loss percentage: 0.487

No, the 16-plus inches of rain in both June and July wasn’t the worst thing about the summer. Slugger Ted Williams had the worst season of his career, batting .254.


Average rainfall: 6.1 inches/month

Average high temperature: 76.9° F

Win-loss percentage: 0.591

This wasn’t a particularly hot summer, but Boston got 25 inches of rain from June through September, making it the second wettest since 1920. The Sox were dominant at Fenway, finishing 52-23.


Average rainfall: 3.3 inches/month

Average high temperature: 80.7° F

Win-loss percentage: 0.549

There wasn’t too much rain in the summer of 2010, just steady heat from June (78.8 ° F) to July (85.8 ° F) to August (81.4 ° F). The Sox were decent, but missed the playoffs--and they haven’t been back since.
