Precipitation

A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Corfu varies significantly throughout the year.

The wetter season lasts 7.0 months, from September 23 to April 24, with a greater than 25% chance of a given day being a wet day. The chance of a wet day peaks at 44% on December 4.

The drier season lasts 5.0 months, from April 24 to September 23. The smallest chance of a wet day is 6% on July 10.

Among wet days, we distinguish between those that experience rain alone, snow alone, or a mixture of the two. Based on this categorization, the most common form of precipitation throughout the year is rain alone, with a peak probability of 44% on December 4.

Daily Chance of Precipitation

The percentage of days in which various types of precipitation are observed, excluding trace quantities: rain alone, snow alone, and mixed (both rain and snow fell in the same day).

Rainfall

To show variation within the months and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day in the year. Corfu experiences very significant seasonal variation in monthly rainfall.

The rainy period of the year lasts for 11 months, from July 31 to June 22, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around November 28, with an average total accumulation of 5.6 inches.

The rainless period of the year lasts for 1.3 months, from June 22 to July 31. The least rain falls around July 11, with and average total accumulation of 0.3 inches.

Average Monthly Rainfall

The average rainfall (solid line) accumulated over the course of a sliding 31-day period centered on the day in question, with 25th to 75th and 10th to 90th percentile bands. The thin dotted line is the corresponding average liquid-equivalent snowfall.

Humidity

We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.

Corfu experiences very significant seasonal variation in the perceived humidity.

The muggier period of the year lasts for 4.3 months, from June 3 to October 11, during which time the comfort level is muggy, oppressive, or miserable at least 15% of the time. The muggiest day of the year is August 14, with muggy conditions 57% of the time.

The least muggy day of the year is February 22, when muggy conditions are essentially unheard of.

Wind

This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.

The average hourly wind speed in Corfu experiences mildly seasonal variation over the course of the year.

The windier part of the year lasts for 5.5 months, from October 25 to April 11, with average wind speeds of more than 4.6 miles per hour. The windiest day of the year is December 3, with an average hourly wind speed of 5.5 miles per hour.

The calmer time of year lasts for 6.5 months, from April 11 to October 25. The calmest day of the year is June 1, with an average hourly wind speed of 3.8 miles per hour.

Average Wind Speed

The average of mean hourly wind speeds (dark gray line), with 25th to 75th and 10th to 90th percentile bands.

The predominant average hourly wind direction in Corfu varies throughout the year.

The wind is most often from the south for 1.5 months, from March 4 to April 20; for 2.7 weeks, from September 26 to October 15; and for 1.3 weeks, from November 13 to November 22, with a peak percentage of 33% on November 17. The wind is most often from the west for 4.8 months, from April 20 to September 15, with a peak percentage of 42% on July 16. The wind is most often from the east for 4.1 weeks, from October 15 to November 13 and for 3.4 months, from November 22 to March 4, with a peak percentage of 37% on January 6.

Water Temperature

Corfu is located near a large body of water (e.g., ocean, sea, or large lake). This section reports on the wide-area average surface temperature of that water.

The average water temperature experiences some seasonal variation over the course of the year.

The time of year with warmer water lasts for 3.2 months, from June 30 to October 4, with an average temperature above 73°F. The day of the year with the warmest water is August 19, with an average temperature of 77°F.

The time of year with cooler water lasts for 4.3 months, from December 20 to April 28, with an average temperature below 62°F. The day of the year with the coolest water is February 25, with an average temperature of 58°F.

Solar Energy

This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents. Shortwave radiation includes visible light and ultraviolet radiation.

The average daily incident shortwave solar energy experiences very significant seasonal variation over the course of the year.

Data Sources

This report illustrates the typical weather in Corfu, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.

Temperature and Dew Point

There is only a single weather station, Corfu International Airport, "Ioannis Kapodistrias", in our network suitable to be used as a proxy for the historical temperature and dew point records of Corfu.

At a distance of 2 kilometers from Corfu, closer than our threshold of 150 kilometers, this station is deemed sufficiently nearby to be relied upon as our primary source for temperature and dew point records.

The station records are corrected for the elevation difference between the station and Corfu according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.

Please note that the station records themselves may additionally have been back-filled using other nearby stations or the MERRA-2 reanalysis.

Other Data

All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Tables of the Sun, Moon and Planets , by Jean Meeus.

All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid.

Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations.

Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory.
