London & Paris Fashion Week 2019 – The Weather Is What You Wear

5th September 2019

London Fashion Week: Friday 13 September – Tuesday 17 September

Paris Fashion Week: Monday 21 September – Tuesday 3 October

 

In this first week of September, there’s a coolness in the air and daylight hours are drawing in.

Seasonal pace of change varies significantly across the year, with the most rapidly changing weeks carrying an emotive feeling.

September and October average 4 minutes daylight loss per day. These are fastest monthly rates of the year* – nearly half an hour each week.

The effect is powerful on the subconscious level. The swiftly shortening days remind us that autumn’s approaching. Even when the weather manages to be warm during September, there’s a sense that such conditions are on ‘borrowed time’. Change is in the air.

It’s likely no coincidence that London & Paris Fashion struts its stuff in these transitional weeks: Thinking ahead to clothing worn in future seasons, exciting the idea of how things might be – and look – different next spring and summer.

Despite a disparity between when London and Paris Fashion Weeks take place, and the season showcased (SS20), a sense of transition and mutability exists both within concepts of contemporary mainstream fashion, and in the weather of these early autumn weeks.

For those attending the shows in only a few weeks’ time, dressing to impress and inspire, what seasonal weather can be expected?

Signs for 2019 in Paris: Great Posing Weather

Two maps, showing the mean (of analogue years) surface air temperatures on the left and mean rainfall per day on the right, for 21st Sep to 3rd Oct (Paris Fashion Week 2019).

 

Our MetSwift analogue** years offer pleasing patterns for Paris 2019. They suggest typical temperatures for the time of year (i.e. maximums in the high teens) along with a little less rain than usual.

I have studied the expected broad-scale weather patterns during the next fortnight, and see little reason to disagree with this. This is due to a teleconnection (from Ancient Greek têle: long-distance) between the tropical Pacific and Western Europe (ergo Paris!). Areas of strong thunderstorm activity are predicted to move eastward across the tropical Pacific this month: An activity that shows a historical connection to increased amounts of high pressure across France (along with Spain and the UK), which corresponds to drier than usual weather.

So, it looks like the weather will be giving us a drier, well-styled walk into autumn this year.

Promising signs… unless, perhaps, you’re modelling rainwear?

* By comparison, July and August average losses of 2 and 3 minutes per day of daylight, respectively. The rate of loss is fastest at the autumn equinox (mid-September) and slowest just prior to the winter solstice (mid-December). There is a matching pattern to the rate of gain during the other half of the year.

** These are historical years (1950-2018) in which Earth’s atmosphere has been found to have behaved most similarly to how it’s expected to in 2019.
