September Starts Meteorological Autumn: Weather Climate Stats For Maryland at Baltimore

Season

September 1 is the start of a new season for meteorologists. We group seasons together in three full month periods. This is the start of Fall for science records and extends through the end of November. The start of astronomical Fall is the Autumnal Equinox on September 22 at 9:03 PM.

Below you will find a look at the numbers for temperature from the National Weather Service, plus daylight, wind, and water temperatures for what we would normally expect throughout the month of September in and around Baltimore.

Climate Data

Sunshine

The sun angle is getting lower, and daily sunlight is shrinking by more than 2 minutes 30 seconds each day in Baltimore:

  • September 1:  Sunrise @ 6:35 AM ; Sunset @ 7:37 PM – Length of Day = 13 hours 02 minutes and 07 seconds.
  • September 30 Sunrise @ 7:01 AM; Sunset at 6:50 PM – Length of Day = 11 hours 48 minutes and 56 seconds.

That is about a loss of 1 hour 13 minutes and 11 seconds daylight by the end of the month.

Average Temperature Change 

 

Here’s the official climate data for Baltimore from the National Weather Service based on records since 1881.

Baltimore will average 11 degrees cooler by the end of the month.

The code at the top of each column:

  • DY = Day
  • NMX = Normal Max (high) Temperature
  • NMN = Normal Min (low) Temperature
  • RMX = Record Max/high Temperatures
  • LMX = Record cool high Temperatures
  • RMN = RMX = Record Main/low Temperatures
  • HIMN = Record warm low Temperatures
  • MXPCP = Max precipitation (daily rainfall)

 

 

  • Hottest: 101ºF on Sept 7 in 1881
  • Coldest: 35ºF on Sept 25 in 1963
  • Wettest: 13.32″ in 2011
  • Driest: 0.09″ in 1884

Note: Normal is NOT Normal! The weather often swings from warm to cool on either end.

Often a big drop in temps is matched by a warm-up a week or two later.  But the string of 90 degree days will be much harder to come by.

Wind Speed

I have heard many complain about how windy the weather has been, especially in the Spring. But not lately. So let’s take a look at the average wind speed per month. Here we can see the lowest average wind is in summer, but as the seasonal shift to cooler weather builds, the wind will likely increase during this month and through Autumn.

 

 

Chesapeake Bay Water Temperatures

Peak water temperatures are at the end of summer, a few months after the longest days and highest sun angle. This is similar to how the daily high temperatures are usually a few hours after high noon.

*Disclaimer due to frequent questions:

I am aware there are some spelling and grammar typos. I have made a few public statements over the years, but if you are new here you may have missed it:

I have dyslexia, and found out at my second year at Cornell.  It didn’t stop me from getting my meteorology degree, and being first to get the AMS CBM in the Baltimore/Washington region. 

I do miss mistakes in my own proofreading. The autocorrect spell check on my computer sometimes does an injustice to make it worse. 

All of the maps and information are accurate. The ‘wordy’ stuff can get sticky. 

There is no editor that can check my work when I need it and have it ready to send out in a newsworthy timeline. 

I accept this and perhaps proves what you read is really from me…

It’s part of my charm.
