The macro climate is influenced by the geographic location (latitude) and proximity to large, climate-moderating bodies of water. The weather may differ from year to year, but the climatic situation over a long period of time is relatively stable in terms of temperature and rainfall patterns.<\/span><\/span><\/p>\n<p style=\"margin-bottom: 0cm;\" align=\"left\"><span style=\"font-family: Arial, sans-serif;\"><span style=\"font-size: small;\">Various factors, combining various climatic components like minimum temperature, maximum temperature, rainfall, humidity, sunshine duration etc., may be used to describe the viticultural potential of a macro-region. Some use monthly data or daily data only, while others are a combination of different scales (daily with monthly data). They are usually summed for different periods of time (growth season or whole year), but can also use a single month. They are established for a specific country or region, and then may be adapted to other regions or used for a systematic global classification of the climate.<\/span><\/span><\/p>\n<p style=\"margin-bottom: 0cm;\" align=\"left\"><span style=\"font-family: Arial, sans-serif;\"><span style=\"font-size: small;\">The length of the growing season of grapes differ from variety to variety and studies shows that at least 170 days of active, frost-free, growing is needed for grape vines to ripen a crop (remember, this figure will not be same for all varieties). But not only the length of the growing season is important; the heat accumulated during the growing season will determine if your grape vine will successfully ripen the grapes or not.<\/span><\/span><\/p>\n<p style=\"margin-bottom: 0cm;\" align=\"left\"><span style=\"font-family: Arial, sans-serif;\"><span style=\"font-size: small;\">You will have to find out how many days of full sunlight with a temperate above 10\u00b0C or 50\u00b0F is measured where you live. This is called the GDD or &#8220;growing degree days&#8221;. Studies made on the physiology of the grape vine, determined that the grape vine is not very active below these temperatures.<\/span><\/span><\/p>\n<p style=\"margin-bottom: 0cm;\" align=\"left\"><span style=\"font-family: Arial, sans-serif;\"><span style=\"font-size: small;\">The GDD is measured by using the following formula:<\/span><\/span><\/p>\n<p style=\"margin-bottom: 0cm; text-align: center;\"><span style=\"font-family: Arial, sans-serif;\"><span style=\"font-size: small;\">(HT + LT) \/ 2 &#8211; 50\u00b0F or -10\u00b0C=GDD * <\/span><\/span><\/p>\n<p style=\"margin-bottom: 0cm; text-align: center;\"><span style=\"font-family: Arial, sans-serif;\"><span style=\"font-size: xx-small;\">HT = highest temp; LT= lowest temp<\/span><\/span><\/p>\n<p style=\"margin-bottom: 0cm; text-align: left;\"><span style=\"font-family: Arial, sans-serif;\"><span style=\"font-size: small;\">By adding up all the GDD points, you can measure your regions suitability for growing grapes and should be more than 2000 GDD (Fahrenheit) or 1200 GDD (Celsius) points. The closer your macro climate is to these numbers, the more suitable it will be for growing grapes.<\/span><\/span><\/p>\n<p style=\"margin-bottom: 0cm; text-align: left;\"><span style=\"font-size: small; font-family: Arial;\">As said earlier, the macro and messo climate cannot be changed, but the micro climate is the one you have control of.\u00a0 Use this advantage to grow your own grape vines more succesfully, even if your messo and macro climate isn&#8217;t 100% ideal.<\/span><\/p>\n<h2 style=\"margin-bottom: 0cm;
