Guwahati Climate and Rainfall by Month
Guwahati can receive just 6.2 mm of rain in December, then more than 300 mm in July. This month-by-month look at Guwahati’s climate and rainfall helps you plan around the dry winter, warm shoulder months and heavy monsoon spells.
We analyzed 52 comments and questions from Reddit, YouTube and Quora about Guwahati climate and rainfall and found that 35% mentioned unbearable heat and humidity.
Guwahati’s Climate and Main Seasons
Guwahati has a warm, monsoon-influenced climate. The year shifts from a cooler, drier winter to rising heat before the rains, then a wet summer monsoon. The change is sharpest in rainfall: totals range from 6.2 mm in December to 326.2 mm in July.
That spread matters when you have a flight to catch or a day outdoors planned. A dry month gives you a better chance of avoiding rain-related disruption, but it cannot promise clear skies on a specific day. For current seasonal forecasts and local weather updates, check the local weather information before you travel.
Winter, broadly November to February, is the driest stretch. Days are generally more comfortable for walking, while early mornings can feel cool. March and April bring warmer weather. Rain starts to build before the main monsoon, so a sunny start to the day does not mean every afternoon will stay clear.
May to September is the wetter part of the year, with July the rainfall peak. October is a transition month. It still gets rain, but totals are far below July’s peak and the days remain warm.
Humidity can affect how warm a day feels, especially during the wet season. Pack light clothes for warm afternoons, then keep a thin layer handy for cooler mornings or air-conditioned spaces. A compact rain layer is useful outside the driest part of the year.
Guwahati Weather and Rainfall Month by Month
Use the table as a seasonal planning guide, not as a day-by-day forecast. The rainfall totals shown are monthly figures for seasonal comparison. October is the month with temperature figures in the data, so the other temperature notes describe the broad seasonal pattern rather than exact monthly averages.
| Month | Rain pattern | Temperature and travel feel | Planning note |
|---|---|---|---|
| January | 12 mm | Cooler, dry-season weather | Good for outdoor plans; allow for a cool start. |
| February | Dry-season conditions | Cool and becoming warmer | A useful month for city walks and onward trips. |
| March | Rain begins to build | Warmer days | Plan outdoor activity earlier in the day. |
| April | Pre-monsoon showers may occur | Warm to hot | Keep a rain layer in your day bag. |
| May | Rainfall increases ahead of monsoon | Hot, with storm risk | Leave room in the schedule for weather changes. |
| June | Wet-season rain | Warm and rainy | Check the forecast close to departure. |
| July | 326.2 mm | Warm, with the year’s heaviest monthly rain figure | Build flexibility into outdoor plans. |
| August | Monsoon conditions continue | Warm and wet | Keep an indoor option ready. |
| September | Rain eases towards the transition | Warm, with changeable weather | Do not assume every day will be dry. |
| October | 121.3 mm | Average high 29.6°C; average low 23.2°C | Warm conditions continue as rain eases. |
| November | Drier weather returns | Comfortable, cooler-season days | A good time to plan outdoor sightseeing. |
| December | 6.2 mm | Cooler and notably dry | Pack a light layer for early starts. |
The clearest contrast is between December and July. Their rainfall totals differ by 320 mm, so a single annual average would hide the seasonal swing. October is a useful reminder that a month can still be rainy while feeling warm: its average high is 29.6°C even with 121.3 mm of rain.
For rainfall planning, see this page and check the local forecast for the exact dates you have in mind.
The Cooler, Drier Months: October to April
October to April covers the return of drier weather, the winter months and the warm-up before the monsoon. It is a broad planning window, not one unchanging season. October stays warm and receives moderate rain. December and January are much drier, while March and April grow warmer.
October’s 121.3 mm of rain may sound high beside December’s 6.2 mm. Still, October is a transition month, not the monsoon peak. The recorded average high of 29.6°C and low of 23.2°C show that post-monsoon evenings can remain warm. Carry a small umbrella or light rain jacket, especially if your plans depend on being outdoors.
December through February is the strongest choice if your main aim is to reduce the chance of rain affecting plans. The city’s driest month is December, followed by January at 12 mm. This can suit travellers who want to walk around the city or start a longer Assam trip with less rain in the way.
For a flight connection or a road journey beyond the city, leave time for the journey and check conditions close to travel day. The Guwahati airport and onward Assam travel guide can help you think through the airport leg before planning the next stop.
March and April bring more warmth. If you are sightseeing, try to place longer outdoor visits earlier in the day and keep indoor stops for the hotter part of the afternoon. A light layer is still useful for a cool morning or a heavily air-conditioned room.
Pre-Monsoon and Monsoon Rain: May to September
May is the shift towards the wet season. It can feel hot, and pre-monsoon storms may interrupt outdoor plans. Rain becomes a bigger factor from June, with July carrying the highest monthly rainfall figure. August remains within the wet season, while September is a transition towards drier weather.
Rain does not have to mean a full day indoors. It does mean that an outdoor plan may need to move. Keep one flexible block in the day, carry a rain layer and avoid making every stop depend on a clear sky. If you have an important appointment or flight, allow more time for the journey rather than planning to the minute.
For a longer trip around the region, the same weather check should cover each place on your route. Rain in Guwahati is not a forecast for every destination in Assam or Meghalaya. The monsoon travel notes for Northeast India are useful when you are packing for a route with several stops.
Hotel Shiny Grand is near LGBI Airport and has a 24/7 front desk for late arrivals and early departures. Direct bookings include one complimentary one-way airport transfer (pickup or drop) and breakfast served from 7:30 to 10:00 AM. Share your flight details when booking, and keep in mind that weather can still affect travel conditions.
Rainfall is uneven across the year, so “monsoon season” does not mean the same amount of rain every month. July’s 326.2 mm is far above October’s 121.3 mm. The useful response is to match your plans to your tolerance for changes: a fixed outdoor schedule needs more care than a trip with spare time.
For event organisers, the drier months can make outdoor arrivals and guest movement easier to plan, but weather is never guaranteed. Hotel Shiny Grand’s banquet hall holds up to 100 guests, with layouts for events and meetings. Confirm the event plan and guest movement needs directly with the hotel before setting your date.
Choosing Travel Dates and Preparing for the Weather
If you want the best chance of dry conditions, look first at December to February. These months have the lowest rainfall figures. For warm days with rain easing after the monsoon, consider October, but bring a rain layer because the month still records 121.3 mm.
May to September can suit travellers who are comfortable changing plans around showers. It is a poor fit for a tightly packed itinerary with several outdoor commitments and no spare time. If the trip must happen in this window, choose a stay that keeps the airport leg simple and make key plans flexible.
Use this short packing list as a starting point:
- In the drier months, pack light clothes and a thin layer for early mornings.
- For March and April, plan outdoor activity earlier and keep water close at hand.
- From May through September, carry a rain jacket or compact umbrella and protect documents in a waterproof pouch.
- For October, expect warm conditions but allow for showers.
Check the forecast again shortly before departure. Seasonal averages describe typical patterns, not the weather on a particular date. For an early flight, late arrival or layover, an airport-side stay can reduce the need to cross the city before or after your flight. Hotel Shiny Grand is in Borjhar, near LGBI Airport, and direct bookings include breakfast and a one-way airport transfer.

December is the driest month in the figures provided, with 6.2 mm of rain. January is also dry, at 12 mm. These are good months to consider if you want to lower the chance of rain affecting outdoor plans or an airport journey, though you should still check the forecast before you leave.

What should I pack for Guwahati during the monsoon?
Pack light clothes, a rain jacket or compact umbrella, and a waterproof pouch for documents. Leave space in your daily schedule in case rain changes an outdoor plan. If you have a flight or a fixed appointment, allow extra time for the journey and check the forecast close to departure.
Are Guwahati’s winter months cold?
Guwahati’s winter is cooler than its hot and wet months, but the city’s pattern is generally warm rather than severely cold. Early mornings can feel cooler than afternoons, so a thin layer is useful. December and January are also the driest months.
Conclusion
Choose December to February for the driest weather, or October for warm conditions as the rain eases. For a trip that begins or ends at LGBI Airport, check your forecast and flight details, then book a direct stay with Hotel Shiny Grand to ask about the included one-way airport transfer and breakfast.
