have been to India for the last 5 years ........ Whilst the weather will be different throughout the country ( Northern area will always be slightly cooler than the south ) But you are always looking into the 29/30 degrees area and the dry time will be in our winter (monsoons are normally between November-ish until April/May 'ish.........The "rain" would be substantial but normally only last for an hour or two and the sun will then be out. Where you are going to is Northern India and therefore suggest "our winter time".......Delhi is a S**t heap and other than the Taj Mahal I would not go their again. The temple at Agra is superb...........As to hot and humid it IS ALWAYS HOT AND HUMID in India and do you Know that the area is one of the closer areas to Afganistan (Rajistan) Buy from Ebay/Amazon "Rough guide to India" and I think that should help you in the country......Visa are a pain as you can only get them from Birmingham/London/Glasgow and you will need to get them into them early as they are not the quickest and also get the right photo for the visa (normal photobooths are not acceptable)... Any m ore let me know
