The short answer: October to March
If you remember only one thing, let it be this: the best time to visit India is broadly October to March. These are the cool, dry months, when the fierce summer heat has faded and the monsoon rains have moved on. Days are pleasantly warm rather than oppressive, the humidity drops away, and the dust settles to leave bright, clear skies.
This is why it is firmly the peak travel season, and why our India tours are designed around it. Whether you are drawn to the Golden Triangle of Delhi, Agra and Jaipur, the romance of Rajasthan, or the gentle waterways of Kerala in the south, the October to March window gives you the most comfortable conditions for walking around forts, palaces and gardens at your own pace. It does mean the popular sights are busier and prices a little higher, but for most travellers the trade-off is well worth it.
The cool season: November to February
For northern India and the headline destinations, the heart of the cool season runs from November to February, and these are arguably the finest months of all. Daytime temperatures in Delhi and across the plains sit in a very agreeable range, often in the high teens to mid-twenties, which is ideal for exploring the Red Fort, the Taj Mahal at Agra and the pink-hued streets of Jaipur without ever feeling overwhelmed by heat.
Rajasthan is at its most beautiful now. The light is soft and golden, the great forts of Jaipur, Jodhpur and Udaipur stand crisp against blue skies, and the desert around Jaisalmer is comfortable to explore by day. There is, however, one gentle word of caution: desert nights and early mornings can be genuinely cold, sometimes dropping close to single figures, and even foggy in December and January around Delhi. A warm layer or two for the mornings and evenings makes all the difference.
Because this is the most popular season, it pays to plan ahead. Our Golden Triangle and Rajasthan tours are timed for exactly these months, when the weather is at its kindest and the great sights are seen in their best light.
Kerala and the south
The south of India follows a slightly different rhythm to the north, and it is well worth understanding the distinction. Kerala and the southern states are at their most pleasant from around October to March, with warm, sunny days that suit the slow pleasures of the region: a houseboat drifting along the backwaters, the tea gardens of Munnar, the spice hills and the palm-fringed coast.
The south is closer to the equator, so it stays a touch warmer and more humid than the north, but it never reaches the same baking extremes as the northern plains in summer. It is also worth knowing that the south has its own monsoon pattern, which behaves differently from the north's, with parts of the region catching rain at slightly different times. For a comfortable, classic Kerala holiday, the October to March stretch remains the safe and rewarding choice, and it is when our Kerala tours run.
The hot months: April to June
From April onwards the temperature climbs quickly, and by May and June the northern plains can become extremely hot, with the mercury frequently passing 40 degrees in Delhi, Agra and Rajasthan. For most older travellers this is genuinely uncomfortable and best avoided; the heat saps energy, makes sightseeing tiring and can be a real strain in the middle of the day.
That said, the hot season is precisely when India's high country comes into its own. While the plains swelter, the Himalayan foothills and the hill stations offer cool, fresh air and a welcome escape, much as they did for the British in colonial times. If you are set on travelling in late spring or early summer, the mountains rather than the plains are the place to be. For the classic palaces-and-monuments itineraries, however, we would gently steer you back towards the cool season.
The monsoon: June to September
The monsoon arrives in roughly June and continues through to September, sweeping up from the south and bringing the rains that the country depends upon. The landscape turns lush and green, the air clears of dust, and there is a certain drama to watching a tropical downpour from a sheltered veranda. Prices are at their lowest and the crowds thin out considerably.
For all that, the monsoon is not the easiest time for the kind of unhurried, sightseeing-led holiday most of our guests prefer. Heavy rain can disrupt plans, humidity is high, and some roads and rural areas become harder to navigate. It is a season with its own charm for the adventurous, but for comfort and reliability we suggest waiting for the skies to clear from October onwards.
India month by month at a glance
Here is a simple guide to the northern climate, using average daytime temperatures for Delhi and how busy each month tends to be. January, around 15 degrees, peak season and lovely if cool. February, around 18 degrees, peak season and very comfortable. March, around 24 degrees, shoulder season and warming up nicely. April, around 31 degrees, quieter as the heat builds. May, around 37 degrees, quiet and very hot. June, around 35 degrees, quiet with the monsoon approaching.
Continuing through the year: July, around 31 degrees, quiet and wet. August, around 30 degrees, quiet and wet. September, around 29 degrees, quiet as the rains ease. October, around 26 degrees, shoulder season and a wonderful time to travel. November, around 20 degrees, peak season and beautifully comfortable. December, around 15 degrees, peak season, cool and clear with chilly mornings. The pattern is clear: the cooler, drier ends of the year are the most rewarding, while the height of summer is best given a wide berth.
What this means for the over-60s
For travellers in their sixties and beyond, the single most important principle is to avoid the heat. The cool season from October to March gives you warm but manageable days, low humidity and the energy to enjoy each fort, temple and garden without feeling drained. It is, quite simply, the most comfortable and forgiving time to see India, and it is when all of our India tours are scheduled.
A little preparation goes a long way. Even in the cool season, pack layers: light, breathable clothing for the warm afternoons, and a warm jumper or jacket for the genuinely chilly desert mornings and evenings, particularly in Rajasthan in December and January. A hat, sunglasses and good walking shoes are essential, and it is always wise to stay well hydrated.
Above all, give yourself permission to take things at a gentle pace. India rewards the unhurried traveller, and our tours are designed with sensible rhythms, comfortable hotels and the support of an experienced guide, so you can savour the country's colour and warmth without ever feeling rushed.
