Breaking it Down Month by Month

We've been living in Narragansett for our entire lives, so here's a locals perspective on what you can expect.


On average, January is one of the coldest months. So if you’re looking for warm Narragansett Town Beach lounging weather, you may want to skip the next few months. The temperature may go as low as 19 degrees, with an average high around 40 degrees. Although the temperatures are cold and uninviting, the surf during the month of January starts to pick up as the occurrence of big, snow-producing nor'easters start to form - bringing some big/powerful surf to the region. Winter wetsuits complimented by thick boots and gloves are a must!

Fun fact: the lowest temperature ever recorded in Narragansett happened on January 11 th, 1942 at -23 degrees. Safe to say there was no one out surfing that day!

Fun fact #2: It is not uncommon to see sea smoke in Narragansett during this time of the year. The water temperatures are still fairly warmer than the air - so on days of extreme cold you can often see the sea steaming. Especially cool if there's a swell in the water!


February is perhaps the coldest (consistent) month of the year with average low of 22 degrees and average high of 43 degrees. Precipitation is almost at the lowest for the year during February at just 3.8 inches. Nor'easter storms and winter swells continues to produce good surf for the area.

Peaky, un-ridden waves like this are not an uncommon sight in February in Narragansett.


Temperatures continue to go up for March, averaging a low of 28 degrees and high of 49 degrees. March is not a popular month for tourists with precipitation at its highest for the year at 5.5 inches. March is typically when we get the last few, large swell producing winter storms.


We continue to get warmer for April with an average low of 37 degrees and average high of 60 degrees. Precipitation drops down to 5 inches, still pretty high. Waves are not as consistent as they are in January and February, but on the plus side - you can regain feeling in your toes when your out surfing!


Now we’re talking. The Narragansett weather finally gets warmer with an average low of 45 degrees and average high of 70 degrees. The precipitation is at a negligible 4 inches. There are plenty of fun waves and no crowds as peak season has yet to start picking up.


Hello, summer! June ushers in the summer months and it feels great! Sun’s out with an average low of 55 degrees and average high of 78 degrees. Precipitation goes a bit higher, but still insignificant at 4.3 inches. There are some lingering swells in early June before the summer flat spells kick in.


Say hello to the warmest month of the year! The weather in Narragansett for July reports at an average low of 61 degrees and average high of 83 degrees. Precipitation is at its lowest for the year at just 3.7 inches. Although major swells are few and far between this time of year, it still feels great to finally shed the wetsuit and hop on the longboard or paddle board!

Don’t forget your sunscreen!


August is pretty similar to July with an average low of 59 degrees and average high of 82 degrees. Precipitation does go up from July to August with the latter bringing in 4.4 inches of rain. Similar surf conditions continue into early August - but hurricane season starts to pick up and there's a good chance you may see a solid hurricane swell around the end of the month! Grab you high performance short board and get on it!


September is the last of the summer months, so if you are reading this and it happens to be September - drop everything and get to the beach! The average low is 52 degrees and the average high is 75 degrees, with average precipitation at 4.2 inches. Hurricane swells are coming through every other week or so (as long as were not in an el nino year!), and the water is still warm. Many of the locals consider September one of the best times to surf in Narragansett (close tie with October).


Temperature drops drastically to an average low of 41 degrees and average high of 65 degrees. It’s still warm Narragansett beach weather and the water still feels nice, so you can still surf comfortably without a thick wetsuit if the other conditions are favorable. Keep your eyes peeled for the last remaining hurricane swell of the season.

The precipitation is virtually the same as the previous 2 months at 4.2 inches.


You may want to start using your 4/3 wetsuit with November introducing average low of 33 degrees and average high of 55 degrees. The precipitation is higher at 5 inches. Swell consistency starts to pick up in November, with rideable waves for half of the month.


The temperature drops further to an average low of 25 degrees and an average high of 44 degrees. Needless to say, they’re not the ideal Narragansett weather numbers for sunbathers, but surfing in this weather is not too bad. Grab yourself a new 4/3 or winter suit and believe it or not you will be cozy out there enjoying some solid winter time surf!
