Does Nice really have a microclimate?

Local France

The city of Nice's tourism website describes it as benefiting from "an exceptional microclimate which contributes to its reputation.
"Open to the sea, the town is protected from the wind by its hills; to the west by the Estérel massif and to the north-west by the barrier of the Mercantour Alps.
"The climate, always mild in winter, is never too hot in summer, thanks to the sea breeze."
What is a microclimate?
According to the definition by the
University of California, Agriculture and Natural Resources
a microclimate is "a local atmospheric zone where the climate differs from the surrounding area. It can be as small as a few square feet or cover hundreds of square miles."

According to
Geo France
magazine, a microclimate can be caused by a number of different circumstances, like proximity to a nearby body of water that absorbs and releases heat more slowly, or a valley fixed between two mountain ranges.
You can also use it to describe
urban spaces
where temperatures tend to be hotter than surrounding areas, thanks to paved roads, high density infrastructure and a lower quantity of trees and green areas.
The term is particularly useful for people working in agriculture, as microclimates can help determine the best places for growing plants.

Does Nice count as a 'microclimate'?
This definition of 'microclimate' is broad and there is no official list of microclimates in France.
Nice often
boasts
having over 300 days of sunny weather a year (or 2,694 hours of sunshine) with an annual average temperature of 16C. However, this is pretty typical for the Côte d'Azur.
It is the Mediterranean sea that helps give Nice its temperate climate - during heatwaves, you might see that inland areas, like
Nîmes and even Avignon
, have hotter weather than Nice. According to
Actu France
, this is mainly because of the city's proximity to the sea, which helps moderate temperatures.
It does appear that Nice is slightly more temperate than other parts of the Mediterranean coast. For example, the average 'high' in Toulon in August is 29.8C, whereas in Nice it is 27.9C.
In terms of whether Nice is the sunniest city in France, this title changes every year - but Grasse, Antibes, Cagnes-sur-Mer, Cannes, Nice, Fréjus, Martigues and Marseille are reliably in the top 10.

What about other 'microclimates' in France?
Brittany is also referred to as the region in France with the highest number of 'microclimates'.
One forecaster, Stéven Tual, told the regional
Quimper outlet of Actu France
that "several microclimates coexist in Brittany.
"Mild weather and more sunshine in the Gulf of Morbihan, while a westerly wind brings more precipitation from Finistère to the Monts d'Arrée, and there are even periods of drought and drier weather in the Bay of Saint-Brieuc.
"It's impossible to list them all, as there are so many variations in the weather in Brittany," he said.
