What is the average temperature in cornwall

The average hourly wind speed in Cornwall experiences significant seasonal variation over the course of the year. The windier part of the year lasts for 4. The windiest month of the year in Cornwall is February , with an average hourly wind speed of 7.

The calmer time of year lasts for 7. The calmest month of the year in Cornwall is August , with an average hourly wind speed of 4.

The predominant average hourly wind direction in Cornwall is from the west throughout the year. To characterize how pleasant the weather is in Cornwall throughout the year, we compute two travel scores. Based on this score, the best time of year to visit Cornwall for general outdoor tourist activities is from late June to early September , with a peak score in the first week of August.

Based on this score, the best time of year to visit Cornwall for hot-weather activities is from early July to mid August , with a peak score in the last week of July.

For each hour between AM and PM of each day in the analysis period to , independent scores are computed for perceived temperature, cloud cover, and total precipitation. Those scores are combined into a single hourly composite score, which is then aggregated into days, averaged over all the years in the analysis period, and smoothed. Our cloud cover score is 10 for fully clear skies, falling linearly to 9 for mostly clear skies, and to 1 for fully overcast skies.

Our precipitation score , which is based on the three-hour precipitation centered on the hour in question, is 10 for no precipitation, falling linearly to 9 for trace precipitation, and to 0 for 0. The growing season in Cornwall typically lasts for 5. Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature.

Based on growing degree days alone, the first spring blooms in Cornwall should appear around May 1 , only rarely appearing before April 18 or after May 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 extreme seasonal variation over the course of the year. The brighter period of the year lasts for 3. The brightest month of the year in Cornwall is June , with an average of 6. The darker period of the year lasts for 3. The darkest month of the year in Cornwall is December , with an average of 1.

For the purposes of this report, the geographical coordinates of Cornwall are The topography within 2 miles of Cornwall contains only modest variations in elevation, with a maximum elevation change of feet and an average elevation above sea level of feet. Within 10 miles also contains only modest variations in elevation feet.

Within 50 miles contains only modest variations in elevation 3, feet. This report illustrates the typical weather in Cornwall, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, to December 31, There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Cornwall.

For each station, the records are corrected for the elevation difference between that station and Cornwall 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 Cornwall is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Cornwall and a given station.

To get a sense of how much these sources agree with each other, you can view a comparison of Cornwall and the stations that contribute to our estimates of its temperature history and climate. Please note that each source's contribution is adjusted for elevation and the relative change present in the MERRA-2 data. All data relating to the Sun's position e. 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 kilometer grid.

Summer is an ideal season to visit Cornwall because of the warm temperatures, and it never gets as stiflingly hot as the rest of England can — Cornwall is a safe haven during national heat waves.

But accommodation and other prices in Cornwall will be high because it is peak tourist season in England. To avoid these inflated prices and still benefit from the warm Cornish weather, early autumn and late spring are the best times to visit Cornwall , especially for those looking to explore the countryside.

Pack a variety of clothing for a holiday in Cornwall because it can experience four seasons in a single day. Take a selection of T-shirts and light jerseys, shorts, skirts and dresses during the summer, as well as beachwear, a hat and sunscreen. Pack some breathable walking shoes or trainers and always have a raincoat no matter what time of year. Warm clothing is essential for autumn, spring and especially winter travellers. Pack thicker jerseys and a coat, long-sleeved shirts and jeans or trousers, long dresses and skirts, and a thermal or two for an unusually cold day.

Raincoats are essential and umbrellas are useful, but only when the wind is not strong. Walking shoes will be fine for winter, but pack sturdier footwear for hiking adventures and a camera to capture the natural beauty of the region. Among wet days, we distinguish between those that experience rain alone , snow alone , or a mixture of the two.

The month with the most days of rain alone in Cornwall is June , with an average of To show variation within the months and not just the monthly totals, we show the rainfall accumulated over a sliding day period centered around each day of the year. Cornwall experiences significant seasonal variation in monthly rainfall. Rain falls throughout the year in Cornwall. The month with the most rain in Cornwall is September , with an average rainfall of 3. The month with the least rain in Cornwall is February , with an average rainfall of 1.

As with rainfall, we consider the snowfall accumulated over a sliding day period centered around each day of the year. Cornwall experiences significant seasonal variation in monthly snowfall.

The snowy period of the year lasts for 4. The month with the most snow in Cornwall is February , with an average snowfall of 9. The snowless period of the year lasts for 7.

The figure below presents a compact representation of key lunar data for The horizontal axis is the day, the vertical axis is the hour of the day, and the colored areas indicate when the moon is above the horizon.

The vertical gray bars new Moons and blue bars full Moons indicate key Moon phases. 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 muggier period of the year lasts for 3. The month with the most muggy days in Cornwall is July , with The least muggy day of the year is February 15 , when muggy conditions are essentially unheard of. 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.
