The Average Wind Speeds in the Principality of the Northern Forests
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 the Principality experiences significant seasonal variation over the course of the year. The windier part of the year lasts for 6.5 months, from September 19 to April 5, with average wind speeds of more than 7.8 miles per hour. The windiest month of the year in the Principality is January, with an average hourly wind speed of 10.2 miles per hour. The calmer time of year lasts for 5.5 months, from April 5 to September 19. The calmest month of the year in the Principality of the Northern Forests is June, with an average hourly wind speed of 5.6 miles per hour.
The Growing Season in the Principality of the Northern Forests
Definitions of the growing season vary throughout the world, but for the purposes of website, we define it as the longest continuous period of non-freezing temperatures (≥ 32°F) in the year (the calendar year in the Northern Hemisphere, or from July 1 until June 30 in the Southern Hemisphere). The growing season in the Principality of the Northern Forests typically lasts for 4.1 months (127 days), from around May 15 to around September 18, rarely starting before April 26 or after June 4, and rarely ending before August 29 or after October 7. The use of warmed arctic greenhouses can greatly extend the growing season for more delicate vegetables.

The information on this site is provided as is, without any assurances as to its accuracy or suitability for any purpose. Weather data is prone to errors, outages, and other defects. We assume no responsibility for any decisions made on the basis of the content presented on this site. We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. While having the tremendous advantages of temporal and spatial completeness, these reconstructions:
(1) are based on computer models that may have model-based errors,
(2) are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and
3) have particular difficulty with the weather in some coastal areas, especially small islands.
We further caution that weather conditions at any given location and time are unpredictable and variable especially in the Arctic Climate, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader.
