“Feels-Like” Temperatures

The way we experience weather isn’t all about temperature. Higher temperatures affect us much more at higher humidity, and colder temperatures feel piercing with high winds. Our perceived temperatures factor in humidity and wind chill to better represent how hot or cold the day feels to a person.

Precipitation (Rain or Snow)

If dry weather is what you’re after, the months with the lowest chance of significant precipitation in Rosetta are August, January, and then October. Note that we define “significant precipitation” as .1 inches or more in this section. The lowest chance of rain or snow occurs around mid to late August. For example, on the week of August 20th there are no days of precipitation on average. By contrast, it’s most likely to rain or snow in early December with an average of 2 days of significant precipitation the week of December 3rd.

When can you find snow in Rosetta? Weather stations report no annual snow. Please note that a value of 0 for snow in the graph below may either mean there was no snow, or that snow is unreported.

Humidity and Wind

Rosetta has some extremely humid months, and high humidity throughout the year. The least humid month is January (71.1% relative humidity), and the most humid month is August (90.1%).

Wind in Rosetta is usually very strong. The windiest month is September, followed by May and October. September’s average wind speed of around 20.8 knots (23.9 MPH or 38.5 KPH) is considered “a fresh breeze.” Maximum sustained winds (the highest speed for the day lasting more than a few moments) are at their highest in late September where average top sustained speeds reach 32 knots, which is considered high wind or moderate gale winds.

Overall Rosetta Travel Experience by Season

Fall (March through May)

Humidity and temperatures combine to make this season feel moderately cold. Highs range from 55.8°F (13.2°C) and 41.1°F (5.1°C) with colder temperatures in the later months. Rain is somewhat common with 6 to 7 days of significant precipitation per month. Fall is fairly slow for tourism, which makes it a good time for those looking for deals.

Winter (June through August)

The middle-year months have freezing weather with high temperatures that are still jacket weather. These months see the least precipitation with 5 to 7 days of precipitation per month. June – August is the slowest season for tourism in Rosetta, so lodging and other accommodations may cost less than usual.

Spring (September through November)

Spring daily highs range from 52.9°F (11.6°C) and 41.1°F (5.1°C), which will feel chilly given the humidity and wind. It rains or snows a significant amount: 6 to 7 days per month. Tourism is the busiest during these months due to the weather, so hotels may be higher priced.

Summer (December through February)

Weather is too cold this time of year in Rosetta to be enjoyable for warm weather travelers. The average high during this season is between 58.5°F (14.7°C) and 50.3°F (10.2°C). On average, it rains or snows a fair amount: 6 to 8 times per month. These times of year are the second busiest with tourists.
