Accumulating 80°F Days

Posted: 07 Oct 2026 05:30 AM, Views: 480
After the rains ended on the first, the weather has thankfully turned drier this October and now warmer with high temperatures on Tuesday well into the 70s and even lower 80s for some. Des Moines hit 81°F, so the featured chart checks in on year-to-date accumulated days with a high temperature of at least 80°F. The green line shows the 2026 accumulation and back during early June, this year was not far off the record pace set by 2012. The few warm days during September has brought the accumulation closer to a simple long term average than the record total. The tan lines show each previous year on record and the intermittent jumps during October show how fleeting these days are this month and how rare they are by November. A couple more such days appear likely over the coming seven days, so try to enjoy them while they last!
