I'll be soon traveling to Geneva, I would like to know how is the weather and when it changes?

I mean for example, if they are in summer, when does it ends, when does the winter begins etc. I actually live in Panama, so here is very humid and mostly hot. Should i buy boots? or heavy coats? I will be leaving Panama around Aug 13, and return about Nov 30th.

GENEVA, SWITZERLAND, however..my question is under a detailed clasification.

Hi!
Here are the following conditions each month, from August to November:

August -
Hours of sunlight per day (average) - 9
Average temperature - 19 degrees celsius
Average precipitation (mm) - 94
Number of wet days per month - 11

September -
Hours of sunlight per day - 7
Average temperature - 16.5
Average precipitation (mm) - 99
Number of wet days per month (over 0.25mm of precipitation) - 10

October -
Hours of sunlight per day - 4
Average temperature - 10.5
Average precipitation (mm) - 72
Number of wet days per month - 10

November -
Hours of sunlight per day - 2
Average temperature - 5.5
Average precipitation (mm) - 83
Number of wet days per month - 11

Compared to the other months of the year, August is the 2nd hottest month, and has the most sunshine, next to July. Also, the amount of sunshine decreases most rapidly when October starts, and the temperature drops by over half when November starts.
In terms of what to pack, you may want to include summer clothes with warm coats, - a wide variety, because Geneva has a wide variety of different weather conditions. It will be cold during November, but it'll also be hot during the summer months.

Have a happy holiday, and I hope this helps!

Geneva, Switzerland.

Oh.

The climate is moderate with no excessive heat, cold or humidity. From July to August the daytime temperature range is 18 to 28 掳C (65掳 - 82掳 F) and from January to February the range is -2 to 7 掳C (28掳 - 45掳 F). In spring and autumn, the daytime temperature range is 8 to 15 掳C (46掳 - 59掳 F). Depending on the altitude the temperature range may vary. It is highly recommended to visitors to pack a sweater, good walking shoes, sunscreen, sunglasses, a compact umbrella and/or a light rain coat.

The weather in Switzerland changes like some people change their underwear. One day it an be very warm and humid and the next it will rain, and rain, and rain.

Summer ending last year was quite odd and we had warmer weather deep into fall. Although this year most of early summer was very cold and spring was exceptionally hot.

Your best bet will be to take clothes for all types of weather since the weather here is very sporadic.
