How these sentences are worded
Each sentence is written from the figures by fixed rules, and says no more than they do. Mild to warm: a mean daily high from 18°C up to 32°C. Hot: 32°C or more. Cool: 10°C up to 18°C. Cold: under 10°C. Dry: under 50 mm of rain in the month; wet: 150 mm or more. Humid: a high of 25°C or more with relative humidity of 70% or more. A month is described as good for going when it is mild to warm and not wet.
The model's grid cell here is mostly sea, so the daily high and low sit closer together than they do on land: afternoons ashore are usually warmer, and nights cooler.
