Mild climate areas
Is there anywhere on earth (on land, mid-ocean would be uninhabitable) where the temperature only rarely, if ever, goes below 0°C or above 30°C? Roger (Dodger67) (talk) 07:33, 11 July 2021 (UTC)
 * San-Francisco? Though sometimes it is above 30. Ruslik_ Zero 08:28, 11 July 2021 (UTC)
 * Auckland, and much of the North Island of New Zealand.- gadfium 08:59, 11 July 2021 (UTC)
 * Guernsey? Santa Cruz das Flores? You can try any small island at temperate to subtropical latitudes. PiusImpavidus (talk) 09:39, 11 July 2021 (UTC)
 * Isles of Scilly has a record high of 27.8°C and a record low of -7.2.
 * Jamestown, Saint Helena has a record high of 33.9°C and a record low of 14.4.
 * Tristan da Cunha has a record high of 24.4°C and a record low of 4.6°C, but it rains for 252 days of the year.

 * The climate of all of Cornwall is very similar to that of the Scilly Isles. --Lambiam 20:23, 11 July 2021 (UTC)
 * Quito. Average high is about 21 degrees Celsius every month of the year, and average low is about 10 degrees every month of the year.  The record low for any month is 2.2 degrees, and only 4 months have ever recorded above 30.  72.77.42.118 (talk) 12:57, 11 July 2021 (UTC)
 * I think that sort of temperature range is fairly typical for Southern England. For the UK as a whole, the monthly averages fit that range: Climate_of_the_United_Kingdom, although there will be days and areas that exceed that. Iapetus (talk) 10:20, 13 July 2021 (UTC)

Ponta Delgada, Azores (Portugal), Population: 70,000: All time min/max in C: 4.5/29.4, 180 rainy days annually. Also reasonable winters with average max of 16.8C in the coldest month. 14:12, 13 July 2021 (UTC)
 * Your described climate seems typical of many areas in the temperate areas, (above the Horse Latitudes at 30 degrees N and S and below 60 degrees N and S. Although, certain areas in this temperature zone will be hotter than others as a result of other factors, such as being in the rain shadow of a mountain range,) I'm sure you will find a lot of areas that meet your description. My town rarely exceeds 30 celcius and rarely dips below 0 C, as well. I'm not sure if this is helpful. AurumIsGold (talk) 01:54, 17 July 2021 (UTC)
 * Oceanic climates (temperate latitudes) are like that (especially very oceanic, no rain shadow such as the aforementioned Tristan da Cunha). Much of Western Europe is oceanic on that article's map but some temperate continents have far less oceanic area. At a weather station of East North America, very exposed to sea breezes (Lewes, Delaware ) it's 30.9C for an average July high, -1.0C for an average January low, 39 to minus 24 (!) for extremes. Perfect latitude for this coast (only 38.77°N), still way too much range. Compare to the Isles of Scilly where the article says leaving the band is extremely rare, despite being too cold (it has never been 27.9 there). Or St. George, Utah which has records of 48 and minus 24 @ 37.1°N and Turpan (China) with 49 and minus 29. @ 43°N. Sagittarian Milky Way (talk) 05:01, 17 July 2021 (UTC)
