We provide here several links to various weather-related sites which cover both historical average and current weather conditions for your upcoming trip.
Weather Almanac / Historic Averages
Weatherbase.com is the best site which has average temperatures, average high/low temperatures and average rainfall for cities throughout Asia. They have collected comprehensive information for 16,439 cities worldwide (in both metric and American units) and it is by far the most easy-to-use, relevant, comprehensive source on the Internet.
BBC’s World Weather Centre also has a comprehensive list of average conditions for many locations across Asia.
If you cannot find your specific destination, say if you’re trekking, you can extrapolate the data by finding the nearest town and calculating the temperatures based on elevation (see your trip itinerary) using the equation of three degrees for every 1,000 feet of elevation gain/loss.
Current Weather Conditions
The user-friendliest site for current weather conditions in Asia is the BBC’s World Weather Centre, however, we would be remiss not to include the Weather Channel’s site as well. Here you can look at the current weather conditions and forecast for your destination.
