You want to see what the weather is going to be for your road biking holiday so we have brought you the best weather resources for the Chamonix and French Alps area. Remember when planning for your trip that you need to take adequate kit for all weather possibilities. Road cycling in pouring rain in just shorts and a short-sleeved shirt is not much of a holiday, especially on the high mountain passes going around Mont Blanc. Ensure that you have packed at least one full waterproof set, and we recommend that you have both a lightweight windproof and a full waterproof jacket available when you are road cycling in the Chamonix and Mont Blanc area.
As with all high mountain environments you have micro-climates and the possibility of rapid changes in the weather. Chamonix being right next to Mont Blanc and such a large glacial area means that a change in wind direction can bring the temperature down considerably.
As you climb uphill the temperature also falls, this is approximately 1 degree celsius for every 100m in altitude. This means that you may well be cycling in 25C in the bottom of the valley, but it could be less than 15C when cycling over a high pass just an hour later. Windchill is also a factor on exposed mountain roads where the temperature can feel much colder. This can occur going uphill, but is even more pronounced on the downhills (the downhill off the Grand Col du St Bernard can last nearly an hour!). This is why we recommend that you always carry a windproof with you, regardless of fine fine the weather looks in the morning!
