There are many national and international services that provide forecasts on weather around the world. To make a list of them all would be impossible. Some larger websites may provide you with what you need in order to prepare for what weather conditions you might meet on your destination.
I have tried to illustrate what you might expect on three websites, using my next two vacations as examples, to show current weather conditions in Marseilles and Barcelona and what weather conditions I may expect in November (Marseilles) and December (Barcelona).
- Current weather: 5-day forecast:
- Severe weather for the US
- Trip-planner, i.e. showing you what weather conditions you might expect base on historical data.
Example: Expected weather conditions in Marseille during our late fall vacation November 25th to November 30th
Example: Expected weather conditions in Barcelona during our late Christmas vacation in Marseille December 23rd to December 30th
- Current world weather after region
- Seasonal averages for cities around the globe
- Country weather guide
