Tegucigalpa month by month
Figures from the Toncontín airport station compiled by the World Meteorological Organization: around 967 mm a year, average highs from 25.4 to 30.2 °C and lows from 14.3 to 18.2 °C. It is one of the least rainy capitals in Central America.
01 A dry capital
Tegucigalpa receives about 967 mm of rain a year. That is a low figure for Central America: considerably less than Guatemala City, and a fraction of what falls on Honduras's Caribbean coast. The reason is position: the capital lies inland, in a valley at 990 metres ringed by mountains that strip the moisture before it arrives.
In practice that yields an almost absolute dry season. January leaves about 5.3 mm, February about 4.7 and March about 9.9, each with one or two rainy days in the entire month. March is also the sunniest month of the year, with some 270 hours.
Temperature plays along nicely. Average highs run from 25.4 °C in December to 30.2 °C in April, and lows from 14.3 to 18.2 °C. Altitude cools the nights: the city's lowest recorded temperature is 4.5 °C, so in January bring a warm layer even if the day is a T-shirt day.
02 The May switch
The change of season here is not gradual, it is a switch. April brings about 43 mm; May, about 144. Within weeks the valley goes from parched scrub and dusty air to fully green.
Seasonal rain comes in afternoon storms. The morning dawns clear, cumulus builds over the mountains ringing the basin and by mid-afternoon it unloads over the city. They are short, heavy and gone.
That pattern is perfectly manageable for a traveller: plan your visits for the morning and leave the afternoon for indoor things. What is not manageable is what happens when the rain stops being an afternoon affair and settles in for days.
03 What happened in 1998
In late October 1998 Hurricane Mitch sat over Honduras for five days. The capital was not hit by wind: it was hit by the accumulated water of the whole upper basin, which came down the Choluteca and its tributaries with nowhere to go.
The river overtopped the Juan Ramón Molina bridge and carried it away. And on El Berrinche hill the slope slid, taking much of the Soto neighbourhood with it: the debris fell into the channel and formed a dam that ponded the river and flooded the low parts of Comayagüela.
That was exceptional and should not be read as a forecast. But it explains the logic of the place well: the seasonal danger here is not Caribbean wind but the combination of steep slopes, soft soils and a narrow channel. From June to November, and above all in September and October, is when that combination gets tested.
04 The July pause
The rainy season does not rise steadily: it has two peaks with a trough between them. June leaves about 159 mm, July drops to 130, August stays at 134 and September climbs again to 177. That pause is known as the canícula across the region.
Its length and intensity vary a great deal from year to year, so it is no basis for precise planning. But it is worth knowing: July and August, which sound like the depths of the tropical winter, are not the worst months on this calendar.
The worst are September and October. Not only for the millimetres, but because they coincide with the most active stretch of the Caribbean cyclone season, and what happens in the Caribbean ends up coming down these rivers even if the cyclone never passes over the city.

05 Verdict
Go between December and March. If you can pick a month, pick February or March: it barely rains, the sun is constant, and the mountain roads — which is how you leave the city for everywhere else — are in their best state of the year.
The price of that window is a dry, dusty landscape, especially in March and April. If you would rather see the valley green, November is a good middle ground: the rain has eased to about 42 mm and the hills have not yet dried out.
Avoid September and October if you have a choice, and if you do not, travel with slack: what gets interrupted here is not the flights but the mountain roads. Check road conditions before each long journey and do not count on arriving on schedule.
