While informative, the statistics that NOAA provides is overwhelming. So, we took the liberty of extracting the most basic information that we feel would be useful to someone interested in growing basil outdoors.
The table below lists the date after which it should be safe to plant basil outdoors in each area of the state. This information is based on NOAA’s calculations for a 10% probability of temperatures falling below 36 degrees Fahrenheit. This means that, on average, there is only a 10% chance that you will see frost after this date. Also listed is the estimated length of the growing season. This is how many days you can expect to have before the risk of frost is greater than 10%.
Please use this information at your own risk. You must take into consideration many varying factors, for example, micro-climates or the presence of valleys and bodies of water, to determine your actual growing season.
