The 10 Best Weather Places in the World
by Antonio Garzón Beckmann
according to Thomas Whitmore (climatology researcher)
Which are the best weather places in the world? This article reproduces the 10 best weather places in the world, according to the classification of the study “Pleasant weather ratings” of the University of Syracuse (Consumer Travel Publications, 1996) which describes and rates the weather for 600 cities around the world. The author of the study is Thomas Peter Whitmore (1946-2012), who was director of climatology research of the University of Syracuse (EEUU).
Previous to the relation of the top 10 cities with the best weather in the world, here is a summary of the methodology applied in the study:
Methodology
The 600 cities of this study are among the more popular for vacations, business travel or retirement with some other representative cities included.
All weather information used in the study was derived from data collected over many years.
Pleasant Weather Ratings rates each half month period for pleasant weather and also provides a single, full-year rating score.
a) Half month ratings and weather descriptions
Each city has a weather profile divided into half month periods (days 1-15 and 16-31) with a symbol for each period, which defines the weather category and related temperatures. The 9 symbols used for the categories and their meanings are the following :
Pleasant weather:
*** 3 white stars: Warm- less rain and clouds (70′s to mid 80′s ºF = 20′s ºC)
“This is a very pleasant weather where daily high temperatures are from 70′s to the mid 80′s (ºF). Although it can rain, there is usually less rain and clouds over the half month period than the average city.”
*** 3 black stars: Mild – less rain and clouds (mid 60′s to 70′s ºF = high 10′s to mid 20′s ºC)
“This is also very pleasant weather where daily high temperatures are from the mid 60′s to the 70′s (ºF). As in the category above, it can rain, but less rain and clouds are likely over the half month period than the average city.
The Mild temperatures are very pleasant to people preferring sligthly cooler weather than the Warm category.”
** 2 white stars: Warm (70′s to mid 80′s ºF = 20′s ºC)
“This is pleasant weather with the same temperatures as the category Warm – less rain and clouds category. Daily high temperatures are from the 70′s to the mid 80′s (ºF). The amount of rain and clouds is at least as much as the typical city in most cases. In the more highly rated categories above there is less rain and clouds.”
** 2 black stars: Mild (mid 60′s to 70′s ºF = high 10′s to mid 20′s ºC)
“This is pleasant weather with the same temperatures as the category Mild- less rain and clouds category. Daily high temperatures are from the mid 60′s to the 70′s (ºF). The amount of rain and clouds is at least as much as the typical city in most cases. In the more highly rated categories above there is less rain and clouds.”
* 1 black star: Cool (mid 50′s to 60′sºF = 10′s to around 20 ºC)
“This is the last pleasant category and well suited to those who prefer cooler temperatures. Daily high temperatures are from the mid 50′s to the 60′s (ºF). A sweater or jacket may be needed to be comfortable during the daytime.”
Hotter weather:
* The “cutted” full moon: Hot (80′s – some 70′s or 90′sºF = mid 20′s to low 30′s ºC)
“This is very good beach weather. It is not included in the pleasant group since some people may be uncomfortable, at times, when temperatures vary up to the higher end of the range. However, others may find the weather enjoyable. Daily high temperatures should be in the 80′sºF (26,6ºC-31,6ºC), and sometimes high readings can vary up in the 90`sºF (32-37ºC) or down into the 70′sºF (21-26ºC).”
* The full moon: Very Hot (mid 80′s – 90′sºF = high 20′s to 30′s ºC)
“This weather can be quite uncomfortable because of the heat. The beach is a good place to be, but may be too hot for some. Daily high temperatures are from the mid 80′sºF (29ºC), to the 90′sºF (32-37ºC). Some cities may climb into the 100′sºF (over 37ºC) during the hottest spells. Care must be taken to avoid overexposure to the heat. The lower readings at night make evenings more enjoyable.”
Colder weather:
* The half new moon: Brisk (40′s and 50′s ºF = mid single digits to mid 10′s ºC)
“This weather is colder with daily high tempeartures in the 40′s ºF (4-9 ºC) and 50′s ºF (10-15 ºC). Sleet, ice or snow are possible if temperatures are the lower end of the range or if below normal weather occurs. The weather can be invigorating, but not as pleasant as the more highly rated categories.”
* The new moon: Cold (30′s to mid 40′s ºF and below = single digits and below)
“This weather can be most unpleasant, Ice, sleet or snow are quite possible and make travel difficult and dangerous. Cold winds add to the chill. A few people may like this weather, but most find it unpleasant.”
In summary, the first two symbols (black and white three stars), represent the most pleasant weather conditions.
b) Full-year rating score
The full-year rating score evaluates the weather over a full year and is used for rating the 600 cities. It has a top score of 100. The calculation method is the following:
“Weather categories are rated 0-10 with 10 assigned to the most pleasant weather (see ratings on attached chart). The cities profiles show the weather twice each month (24 times a year). Each of the 24 boxes in the profile is assigned a category rating based on the weather category. For example, if January 1-15 isBrisk, that box receives a rating of 4. The ratings of the 24 boxes are then added together to reach one preliminary score for the year. The preliminary score is then divided by 2,4 putting the score on a scale of 0-100 and making the final full-year rating score.”
The top 10 (of the 600 cities)
So this are the top 10 cities with the best weather in the world, according to the study of Thomas Whitmore, in increasing order of importance:
10. San Luis Obispo (California, USA) / Rating Score=92
