A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Canterbury varies throughout the year.
The wetter season lasts 4.3 months, from September 23 to January 31, with a greater than 26% chance of a given day being a wet day. The chance of a wet day peaks at 33% on October 14.
The drier season lasts 7.8 months, from January 31 to September 23. The smallest chance of a wet day is 19% on April 26.
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 33% on October 14.
Daily Chance of Precipitation
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. Canterbury experiences some seasonal variation in monthly rainfall.
Rain falls throughout the year in Canterbury. The most rain falls during the 31 days centered around October 22, with an average total accumulation of 2.3 inches.
The least rain falls around March 13, with and average total accumulation of 1.2 inches.
Average Monthly Rainfall
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.
The perceived humidity level in Canterbury, as measured by the percentage of time in which the humidity comfort level is muggy, oppressive, or miserable, does not vary significantly over the course of the year, remaining a virtually constant 0% throughout.

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 windier part of the year lasts for 5.4 months, from October 6 to March 19, with average wind speeds of more than 7.7 miles per hour. The windiest day of the year is January 1, with an average hourly wind speed of 9.4 miles per hour.
The calmer time of year lasts for 6.6 months, from March 19 to October 6. The calmest day of the year is July 28, with an average hourly wind speed of 6.0 miles per hour.

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.

This report illustrates the typical weather in Canterbury, 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 are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Canterbury.
For each station, the records are corrected for the elevation difference between that station and Canterbury according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
The estimated value at Canterbury is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Canterbury and a given station.
The stations contributing to this reconstruction are: Kent International Airport (71%, 19 kilometers, northeast), London Southend Airport (22%, 42 kilometers, northwest), and Le Touquet – Côte d'Opale Airport (7%, 93 kilometers, southeast).
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.
