Grand Rapids (WZZM) - Halloween can be spooky enough but the weather is rarely ever scary! Last year (2010) was rather pleasant with temperatures reaching 55°F in the afternoon with 90% of the possible sunshine (and no rain).
Out of 118 years of record keeping, rain has fallen on 53 Halloweens, or 45% of the time. Rain fell in 2009, and again in 2007, but the most rain was in 1994 when 1.27" drenched the area.
Snow is extremely rare; in fact, the last time any snowflakes were seen was in 1949; measurable snow has fallen only twice: 0.3" in 1932, and a record 1.5" in 1917.
Sunshine has averaged 34% since 1905 with 100% sunshine last occurring in 2008.
The warmest Halloween occurred in 1950 when the temperature warmed to 79°F while the coldest Halloween afternoon was 32°F in 1917 when all that snow fell.
