The 'real' fall

Posted: Updated:
PHOENIX (3TV/CBS 5) -

It’s fall, y’all!  Well, almost…..

After a long, hot summer in Arizona, we get VERY excited about even the mention of fall. Steaming hot pumpkin spice lattes seem silly when it’s 108 degrees out still in September. But we start to daydream anyways about boots, scarves and changing leaves.

Although we’re sweating it out while waiting on Mother Nature to give in, technically it IS fall. In one sense of the word, at least. Meteorological fall began September 1. September, October and November are considered fall.

Then there’s astronomical fall. That begins with the arrival of the Autumnal Equinox on September 21 and ends with the Winter Solstice on December 21.  Astronomical seasons are based on the position of the Earth in relation to the sun. The upcoming autumnal equinox will mark the time when the sun passes directly above the equator.

Meteorological seasons are based on the annual temperature cycle. Meteorologists and climatologists tend to favor the meteorological seasons, which typically better match up with when we actually FEEL a difference in temperatures and seasons. And by “we,” I mean everyone but Arizona. I’m kidding….kind of. 

Here in the Valley, we know it usually takes until around Halloween before we feel an actual cool-down. When we look at the climate, or long-term weather of our region, we see that our last 100 degree day is typically around October 3rd. That’s only a few weeks away! Our last 90 degree day of the year comes just a few weeks later around October 28th. Our last 85 degree day happens less than two weeks later around November 9th. Temperatures tumble so quickly in October and November in the Valley. No wonder we get so excited about fall around here! We may have to wait a little longer for autumn to get here, but it’s so very worth it when it finally does. Hang on, Phoenicians….it’s just around the corner!

    We're currently tied for the fourth warmest start to the month of November in Phoenix. Just a little over a week away from Thanksgiving, will Mother Nature finally give in and provide fall-like weather for the holiday?
