Question 1

When is the best time to visit Delhi based on 2025 weather?

Accepted Answer

The best time to visit Delhi is from late October through November, when 2025 data shows pleasant temperatures, dry skies, and plenty of sunshine. This short window sits neatly between the soaking summer monsoon and the chilly heart of winter.

In November 2025, Delhi averaged a comfortable 19.5°C (67.1°F), with daytime highs around 30.9°C (87.6°F) and cool nights near 10.3°C (50.5°F). The month recorded **0 mm of rainfall** and 318.9 hours of sunshine, making it ideal for sightseeing. October was also excellent, averaging 25.5°C (77.9°F) with just 25.5 mm of rain.

These months stand in sharp contrast to the rest of the year:

- **June 2025** was the hottest, averaging 31.7°C (89.1°F) and peaking at a scorching 43.6°C (110.5°F).
- **July–September 2025** brought the monsoon, dumping 463 mm of rain with humidity around 77%.
- **January 2025** was the coolest month at 13.9°C (57.0°F), with foggier, damper mornings.

For travelers, this means planning a Delhi trip for autumn delivers the most reliable comfort. The dry, sunny conditions of November 2025 were perfect for exploring outdoor monuments and markets without the extreme heat of early summer or the heavy showers of the rainy season. If autumn isn't possible, February and March 2025 (averaging 18.8°C and 24.0°C) offer a pleasant secondary window before Delhi heats up again.

Question 2

How hot does Delhi get in summer?

Accepted Answer

Delhi gets intensely hot in summer, with the peak heat arriving in June 2025 when daytime highs reached up to **43.6°C (110.5°F)** on June 11 — the hottest day of the season.

During the summer months of June to August 2025 (meteorological summer, JJA), Delhi's average daytime high was **33.6°C (92.5°F)**, while the overall mean temperature sat at **29.8°C (85.6°F)**. The most extreme heat was concentrated in the pre-monsoon stretch of early-to-mid June, when Delhi averaged daily highs of **36.4°C (97.4°F)**.

A few more data points from the 2025 season highlight just how harsh the heat can be:

- **8 days** climbed to 40°C (104°F) or above, with **4 days** at 43°C (109°F) or hotter.
- The warmest night reached a sweltering low of **31.8°C (89.2°F)** on June 13, offering little overnight relief.
- Once the monsoon arrived in mid-June, average humidity rose to **74.7%**, swapping dry heat for muggy, sticky conditions.

In practical terms, Delhi's summer is best approached with caution. The combination of extreme temperatures and, later in the season, high humidity makes midday outdoor activity risky, so plan sightseeing for early morning or evening, stay well hydrated, and seek air-conditioned spaces during peak afternoon hours.

Question 3

How much rain does Delhi get during the monsoon season in 2025?

Accepted Answer

Delhi received about **547 mm (21.5 inches)** of rain during the 2025 monsoon season (June to September), which accounted for roughly 80% of the city's entire annual rainfall of 683 mm (26.9 inches).

The monsoon delivers the overwhelming majority of Delhi's precipitation. In 2025, rainfall built up month by month, peaking in July with **179 mm (7.0 inches)** — the wettest month of the year — followed closely by August at **160 mm (6.3 inches)**. September remained wet with 124 mm (4.9 inches), while June eased the city in with 84 mm (3.3 inches).

These rains also bring high humidity and muggy conditions. Across the June–September monsoon months, Delhi's average humidity climbed to about 73%, with average temperatures around 29.8°C (85.6°F). The contrast with the rest of the year is striking: the dry pre-monsoon stretch from January to April produced just 49 mm (1.9 inches) of rain combined.

For visitors and residents, this means Delhi's weather in 2025 was sharply split between a long dry season and an intense, concentrated wet season. If you are planning travel during the monsoon, expect frequent heavy downpours, sticky air, and occasional waterlogging on the roads — but also cooler, greener surroundings than the scorching pre-monsoon heat. Travelers hoping to avoid the rain should target the dry months on either side of the monsoon, when Delhi sees very little precipitation.

Question 4

What is the annual temperature range in Delhi in 2025?

Accepted Answer

Delhi had a wide annual temperature range in 2025, swinging from a cool monthly average of 13.9°C (57.0°F) in January to a peak of 31.7°C (89.1°F) in June — a spread of about 17.8°C (32.0°F) between the coldest and warmest months.

Looking at daily extremes across the full calendar year (January to December 2025), the contrast was even sharper. The lowest monthly minimum in Delhi was 6.7°C (44.1°F) in January, while the highest monthly maximum reached 43.6°C (110.5°F) in June. That gives a full-year extreme spread of roughly 36.9°C (66.4°F).

A few key data points from 2025 illustrate Delhi's strongly continental climate:

- **Coldest month:** January, averaging 13.9°C (57.0°F)
- **Warmest month:** June, averaging 31.7°C (89.1°F)
- **Annual mean temperature:** 24.9°C (76.8°F)

The pattern shows a clear progression: a chilly winter low in January, a steep climb into the pre-monsoon heat of April through June, then a milder, more humid plateau during the monsoon months before cooling again toward December at 15.7°C (61.3°F).

For visitors and residents, this means Delhi demands a flexible wardrobe across the year. Light layers and sun protection are essential from April to June, while the December–January window calls for warmer clothing, especially in the cooler mornings and evenings. The most comfortable, moderate temperatures in 2025 fell in the transitional months of October, November, and early March.

Question 5

What is the sunniest time of year in Delhi?

Accepted Answer

Delhi is sunniest in spring and early summer, with April 2025 topping the year at 365.2 hours of sunshine — roughly 12.2 hours of sun per day.

Across the full 2025 calendar year, Delhi recorded 3,731 total sunshine hours, averaging about 10.2 hours of sun daily. The three brightest months all fell in spring (March to May): April led with 365.2 hours, followed closely by May at 357.3 hours and March at 356.1 hours. Together, spring 2025 (March 1 to May 31) delivered 1,078.6 hours of sunshine. April was also notably dry and clear, with humidity averaging just 28.7% and mean temperatures of 31.0°C (87.8°F).

By contrast, the cloudiest stretch in Delhi came during the winter and monsoon periods. January 2025 was the least sunny month at 265.1 hours (about 8.6 hours per day), when cooler temperatures of 13.9°C (57.0°F) and morning fog limited sunshine. The July–August monsoon also dimmed the skies, dropping to 267.8 hours in August as rainfall peaked.

For travellers and outdoor planners, this means the clearest, brightest skies in Delhi arrive in March through May. Just keep in mind that those long, sunny April and May days come with intense heat above 31°C (88°F), so early mornings are best for sightseeing and activity during Delhi's sunniest season.
