Definitions of the growing season vary throughout the world, but for the purposes of this report, we define it as the longest continuous period of non-freezing temperatures (≥ 0°C) in the year (the calendar year in the Northern Hemisphere, or from 7月1日 until 6月30日 in the Southern Hemisphere).
The growing season in 莱西 typically lasts for 6.1个月 (188天), from around 4月21日 to around 10月25日, rarely starting before 3月30日 or after 5月12日, and rarely ending before 10月5日 or after 11月14日.
Time Spent in Various Temperature Bands and the Growing Season in 十一月
The percentage of time spent in various temperature bands: frigid < -9°C < freezing < 0°C < very cold < 7°C < cold < 13°C < cool < 18°C < comfortable < 24°C < warm < 29°C < hot < 35°C < sweltering. The black line is the percentage chance that a given day is within the growing season.
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. In this report, we use a base of 10°C and a cap of 30°C.
The average accumulated growing degree days in 莱西 are essentially constant during 十一月, remaining within 6°C of 1,050°C throughout.
The average growing degree days accumulated over the course of 十一月, with 25th to 75th and 10th to 90th percentile bands.

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 our travel scores are only as good as the data that underpin them, that weather conditions at any given location and time are unpredictable and variable, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader.
