EBC Trek in April: Peak Season, Rhododendrons, and What to Expect

Last updated 2 October 2026. The temperature and rainfall figures below are published station averages, not forecasts, and each table names its source. Above Dingboche there is no station data, so what I describe there comes from our guides, not from a number.

The short answer: April is one of the two best spring months for Everest Base Camp. The days are warm by Himalayan standards, rain is still low, the nights are milder than in March, and the rhododendrons are in flower below and around Namche. The trade is company on the trail and some afternoon haze. If you want the flowers and the warmth, April is the month. If you want a quiet walk, it is not.

This is the month guide. For the full year and the weather behind it, see Everest Base Camp weather month by month, and for the choice across all seasons, the best time to trek to Everest Base Camp. The trek is our Everest Base Camp trek, 12 days, from US$1,399 Budget, US$2,499 Standard and US$4,999 Luxury.

What is the weather like on the Everest trail in April?

There is no weather station at Base Camp with a long record, so I use the four stations along the route that have one: Lukla (2,786 m), Namche Bazaar (3,450 m), Tengboche (3,857 m) and Dingboche (4,410 m, modelled data, not an instrument record). Each cell is the average daily high, then the average daily low, in degrees Celsius, with March and May alongside.

Sources: Lukla, Nepal Department of Hydrology and Meteorology (DHM) 1991 to 2020 normals. Namche, FAO FAOCLIM database. Tengboche, FAO and the Australian National University record. Dingboche, a computer model of the location, so a guide and not a measurement. The sources are listed in the notes at the end.

Rain in April, in millimetres, is 58.7 at Lukla, 26 at Namche, 25.2 at Tengboche and 13 at Dingboche (modelled). Lukla is a little wetter than in March (45.3) and about half of May (127.6). So April is the middle of the dry spring: Namche's average night is just above freezing (0.8 degrees), and the build-up to the monsoon has not started.

I have no station data above Dingboche. Lobuche, Gorak Shep and Base Camp are higher and colder than Dingboche, and nights there are well below freezing in April. The old figures I once printed on this page for those stops (minus 10 to minus 18) had no source, so I have removed them. From our guides' experience, sleeping at Gorak Shep in April is less punishing than in October or November, but it is still a cold night.

Why do people say April is best?

At Gorak Shep, the last settlement below Base Camp at 5,164 m, the best times for trekking are spring (March and April) and autumn (October and November), when Everest visibility is ideal and the temperature is not excessively cold. The same entry notes that in autumn competition for beds in the lodges can be intense. April gives you the warmer nights that November does not, and flowers that October does not, which is the reason it holds its place.

Are the rhododendrons in bloom in April?

The tree rhododendron, Nepal's national flower, flowers in early and mid spring, with red, pink or white blooms. Sagarmatha National Park's entry lists rhododendron among the trees of the subalpine forest. The sourced detail ends there. From our guides, the forests between Lukla and Namche and around Tengboche are at their best from about the first week of April, the bloom moves higher up the valley as the month goes on, and the date shifts with the winter. Flowers are the one thing April does that October cannot, and the first three weeks are the part I would pick. The sight is a red and white forest in front of snow peaks. It is not a guarantee, because a late or early year can move it by a couple of weeks either way.

How crowded is April?

There is no month-by-month count of trekkers on the Everest trail. The Nepal-wide picture is this. Nepal Tourism Board figures for 2024 show 111 thousand international arrivals in April, against 128 thousand in March, 124 thousand in October and 114 thousand in November. That is all of Nepal, not Everest, and it puts April just behind those three months. On our own trail, April is a busy month: our best-time guide rates March as "building" and April as "high". That is our judgement and not a count.

What busy means in practice, from what our guides see: lodge dining rooms where you share tables, queues at suspension bridges in the morning, and a full Kala Patthar at sunrise. If crowds bother you, March is colder, and November is quieter. If you enjoy sharing the trail, April has a good atmosphere.

Will the Lukla flight run in April?

There is no published month-by-month cancellation rate for Lukla. The airport regularly closes from mid to late morning when strong south-west winds begin, and a sudden loss of visibility closes it because there is no go-around. In April, rain at Lukla is moderate, but a busy month means a bad day creates a backlog.

Our flight guide, Nepal domestic flights for trekkers, says the fixed-wing flights leave from Manthali airport in Ramechhap, not Kathmandu, in roughly 15 March to 15 May. That means a hotel pick-up between midnight and 2 am and a four to five hour drive, and the dates are set by the Civil Aviation Authority of Nepal, not by us, and can shift. A helicopter flies Kathmandu to Lukla direct and is included on our Luxury tier. In a peak month a single bad day can take two or three days to clear, so never book your international flight for the same day as your Lukla return. Leave 24 hours, or 48 if you can.

Is the haze a problem in April?

From our guides' experience, April mornings are blue and clear and cloud tends to build from midday, with a milkiness in the air that softens distant peaks compared with October. This is observation, not a measurement. Plan your best pictures for before about 10 am. Afternoon showers are possible but rarely heavy, and Namche's 26 mm for the whole month supports that. The light at Kala Patthar sunrise is a little warmer-toned than in autumn. The World Health Organization's fact sheet says UV rises with altitude and can be high even under cloud, so wear sunscreen and sunglasses on grey days.

Is April safe at Base Camp?

April is also the month the climbing teams prepare their route, and two serious events have happened at Base Camp in April, so you should know about them. An avalanche on 18 April 2014 killed 16 Nepali climbers who were preparing the route through the Khumbu Icefall. Its entry on the Everest base camps records that on 25 April 2015 a 7.8 earthquake triggered an avalanche from Pumori that swept through the camp, and that at least 19 people were killed. Both events were exceptional. On our trek you stay in the part of Base Camp open to trekkers and never enter the Icefall, and we check conditions before every departure.

What should I pack for April?

This is advice from running the route, not data. April is the warmest of the cold-night months, but warm for the Himalaya still means freezing at 5,000 m.

On our Everest Base Camp trek we lend a down jacket and a sleeping bag (see the package page for what each tier includes), so the cold is a comfort question and not an extra cost. The full kit list is in our Everest Base Camp packing list, and the climb protocol is in our altitude sickness guide.

How does April compare with October?

The station data puts Dingboche's lows at -7.0 and -5.3, so April nights are not warmer than October's at Gorak Shep. See EBC in autumn for the other season.

When should you NOT trek to Everest Base Camp in April?

Skip April if you want a quiet trail, or if sharing a dining room with strangers will spoil it for you. Skip late April if you want the clearest afternoons, because the build-up toward May has begun. Skip it if you hate the Ramechhap pick-up between midnight and 2 am. And skip any month if you cannot spare a buffer day, which is the single most common cause of a missed connection.

Is the Everest region open right now?

As at 29 September 2026, the date of my latest status update, the Everest region was open and unaffected by the late-August Rasuwa flood and the late-September rain, which hit other river systems. This can change, so I keep the live position region by region on my late-September floods travel update, and I recheck before every departure.

What does the trek cost and how do I book?

Prices do not change with the month. The 12-day Everest Base Camp trek is US$1,399 Budget, US$2,499 Standard and US$4,999 Luxury for one person, with a lower price per person for larger groups. Budget has no porter. Standard has one porter for two trekkers. Luxury has a dedicated porter for each trekker and a return helicopter to Lukla. Kathmandu hotels are not included in any trek tier. A 10 per cent deposit holds your dates and the balance is paid in Kathmandu. Plans change? You can reschedule for free, with at least 72 hours' notice, to any date within one year. The deposit itself is not refunded if you cancel.

The dates currently listed on our trek page for April 2027 are 5, 12, 19 and 26 April. April is a busy month, so ask early for mid-April starts.
