The showers of April?

April is a transition month. It is usually pleasant, but sometime this month, I will have to use the air-conditioning for the first time. The majority of Aprils do not reach 90, but I have a feeling we will this year!

Despite some decent rains in March, including the last day of the month, the year has continued very dry. Normal rainfall by April 1st is 10.57" (the 1971-2000 average was 11.71"). So far this year we have had 6.67". Last year we have had 7.11". In 2010, which turned out to be the driest year on record, we had 8.74" by April 1st. So the drought continues, and it is very scary.

March 2012 was the warmest March on record at St. Simons Island. The average temperature was 68.2 degrees and 7.9 degrees above normal. This March was warmer than the average April! We have had to use the air conditioning frequently since March 16. Encouragingly we were slightly wetter than average, with rainfall of 4.01", which is 0.13" above normal. I hope April also has decent rains.

Some highlights from March and the previous winter:

At St Simons Island, the warmest ever March was helped in part to the extended period of onshore flow and the warmer than normal Atlantic ocean water temperatures. In fact the minimum temperature for the month was only 46 degrees, which was also an all-time record. A daily record high of 85 degrees was set on March 29th, and a total of six daily record high minimum temperature records were broken as several nights only fell into the mid to upper 60s. A total of only 4 freeze events (days with minimum temperature less than or equal to 32 degrees) were recorded during the winter of 2011-12, this is below the average number of 11 freeze events for the winter season. This is the fewest amount since the winter of 1997-98.

March 2012

March is usually a mild and pleasant month. Seabreezes cool the afternoons and keep us considerably milder than inland, where temps reach the 70s with ease and 80s frequently. The past 2 Marches we have not had to use our air conditioning. We will see how that goes. March averages 3.88" of rain, up from 3.47" in February. Most of this increase comes from the longer month. The average temperature for March is 60.8 degrees, up 5.8 degrees from February.

February 2012 was very warm, with a temperature averaging 4.8 degrees above normal. All our winter months have averaged more than 4 degrees above normal, which may be a unique occurrence. February continued our dry streak as well, although some significant rains on February 19th, 22nd, and 27th helped. I hope that pattern continues in March!

During February 2012 3 new record daily highs were set and 1 daily record high was tied. List is below. One new record high low was also set, which tied the record for the warmest low in February. No record lows or precipitation records were set during February.

February 2012

January was warmer than normal and very dry! We had a sharp freeze on January 3-4, but much of the month was warm. The average temperature at KSSI was 55.6 degrees, which is 4.1 degrees above normal.

Rainfall was very low, 0.45", which is 2.77" below normal. A very discouraging start to the year. Perhaps this will be the 7th lean year in a row for rain. We had been hoping not after the exceptionally dry years of 2010 and 2011. But we get what we get.

We tied one record during January. On January 24, we tied our record for the warmest low temperature, 59 degrees. The record was previously set in 2002.

February is a transition month here, but still wintry by our standards. Days are cooler than you might thing in south GA, being moderated by the cool ocean. Freezes are half as frequent as in January, however. And by late in the month, even afternoon temperatures start to rise enough to notice.

The average rainfall increases slightly in February, to 3.47", vs 3.22" in January. I really hope we exceed the normal! Average temperature in February is 54.3 degrees, up 2.9 degrees from January.

8 day model forecast graphic:

January and a few 2011 highlights.

2011 continued to be very dry, with a rainfall of 29.25", the third lowest annual total since records began in 1948. It was better than the 24.27" of 2010, but not much better. This is the first time that we have had two consecutive years below 30". We also had a very hot summer, with a record total of 90+ days for the year. I hope this year will be wetter! Heck, 3 feet of rain this year would be nice.

August 2011 was our hottest August on record. We also set a record for the most days of 90 or higher (30), and had our second longest streak of consecutive 90+ days.


December 2011 was warm and dry. No freezes occurred during the month. That is a bit unusual, but not rare. A coming arctic cold wave assures we will have freezes during the first week of January. The lack of freezes has allowed a lot of gnats to survive, which is annoying.

December had an average temperature of 58.7, which is 4.6 degrees above normal. Rainfall was 1.32", exactly half of the average monthly total of 2.64". Warm and dry. Again. Almost all the rain fell on December 12th.

January is normally our coldest month, with an average temperature of 51.4 degrees according to the 1981-2010 normals. January also averages a little wetter than December, with a monthly total of 3.20". I hope we are above average this month. That may not mean much--both 2010 and 2011 saw rainfall near or above normal in January, before the rest of the year became crackingly dry.

The latest monthly normals for 1981-2010 vs 1971-2000 show January having 0.48" less rain and being 0.3 degrees colder.

On January 24 St. Simons Island tied their record warmest low temperature of 59 degrees. The record was originally set in 2002.

8 day model forecast graphic:

December, the onset of winter.

November was a little warmer than normal and, as has been typical for the past two years, a drier than normal month. The average temperature was 62.6, 0.8 degrees above normal. Rainfall was 1.15", 0.88" below normal. Rainfall was 57% of normal.

Despite that, a daily rainfall record was set on November 23, with 0.73". The old record was not much, 0.09" in 1977. That was the only record of any kind set in November.

December is usually a little wetter than November, rainfall increasing to 2.62" from 2.03", or 30%. Let's hope we have a wet December to close out the year!

December has falling temperatures through the month, but not in an intuitive way. During the first week of December average temperatures fall the fastest of the year, not in October or November as you might expect. December 4th has the greatest temperature fall of any day of the year, with a fall of 0.45 degrees. December 5th and 12th are in second place with a daily fall of 0.4 degrees. No other days have a fall of 0.4 degrees or more. There is also a pause in the temperature fall from December 15-18. On December 1, the average high is 66.5 and by December 31 the average high has fallen to 60.4, a fall of 6.1 degrees. On December 1 the average low is 49.7, which falls to 43.7 by December 31, a fall of 6.0 degrees.

On December 7, St. Simons Island tied its record high of 79. This record was originally set in 1971.

On December 7-8, at my home the temperature dropped 39.7°F from high to low. This ties the greatest temperature change in 24 hours or less since I started observations in November 2003.

November, the finest month!

November has the finest weather on St. Simons Island. We like winter, and we have it to look forward to. But sometimes it is too cold, although almost never very long. But November is a mild, dry month. The driest month of the year! And almost always mild. Sometimes warm or cool, but almost never hot or cold. Some Novembers stay below 80 and never reach 40.

Temperatures continue to fall steadily through November. November 1st starts the month with an average high of 73.0 and an average low of 56.9 By November 30 the average high has fallen to 66.6 and the average low to 49.8 Rainfall is light during November, and the majority of Novembers do not have a day receiving an inch of rainfall. Snow, sleet, or ice have never been recorded.

October was a cool and dry month. Our rainfall (again) was well below normal. We received 2.25", and were 2.21" below normal. Barely 50%. An improvement from the 1/3 of normal rainfall we received in September. But still. Rainfall so far this year has been 26.78" officially, and ended October 13.55" below normal.


On October 2nd, St. Simons Island tied its record low of 51. This record was also set in 1984.

On October 15th, St. Simons Island tied its record high of 86. This record was also set in 1972.

October 19 also saw our pressure fall to 29.44" / 997.0 mb. This was our second lowest pressure reading in the past 8 years when I started keeping records.

The Hunt for Wet October

September 2011 was warmer and drier than average. The temperature departure was not exceptional, with the average being 79.1 degrees, 1.0 degrees above normal. Despite the above average temperature for the month, two record lows were recorded on September 8 & 9, breaking the old record lows by 1 degree on both days.

Rainfall was exactly 1/3 of the average, 1.92" vs. an average of 5.76".

As was the case last year, October finds us in continuing drought. We have exceeded last year's rainfall total already, but we are more than 11" below normal for the year.

October is a pleasant month on St. Simons Island, with summer gradually losing its grip. Temperature averages are somewhat misleading, since this is the season of our "Lake Wobegon Days" when most of our days are above average. How can this be? The answer is that we are an island, and the ocean is warm. Cold snaps can bring us down 10 or 15 degrees below normal for a day or two, then the maritime influence reasserts itself, with long stretches of days 2, 3, 4 degrees above normal. About 70% of our days in October have above average temperatures!

Average daily rainfall decreases rapidly through October. October 1 averages 0.177" of rain. By October 31 this falls to less than half, with a 0.086" daily average. Average temperatures fall steadily through the month, with October 1 averaging 67.1 / 81.1, falling to 57.2 / 73.3 by October 31. These are the 1971-2000 averages, and new averages for the 1981-2010 period will be available shortly. I will begin using these new averages when they become available.

On October 2nd, St. Simons Island tied its record low of 51. This record was also set in 1984.

On October 15th, St. Simons Island tied its record high of 86. This record was also set in 1972.

The noreaster of October 8th to the 12th, long heralded by models, was disappointing. For days the weather computer models showed us getting 6" of rain or more. Officially we got less than an inch, and 1.21" at my house. That was nice, but didn't put much of a dent in the drought.

The storm of Oct 18-19 did not bring heavy rains or destructive winds but did bring our second lowest pressure of the past 8 years, with a minimum of 29.44" (997.0 mb.)
