Hanoi weather month by month<\/h2>\n

These are long-term averages for central Hanoi: the L\u00e1ng weather station in \u0110\u1ed1ng \u0110a district, 1991\u20132020 climate normals from the Vietnam Institute for Building Science and Technology, as reproduced in Wikipedia’s Hanoi climate table. Any single year can be hotter, colder, wetter or drier than this.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

Rainfall is the monthly average total, rounded; rainy days are rounded averages; sunshine is average hours per month. Over a whole year Hanoi gets about 1,600 mm of rain on roughly 114 days, and the mean temperature is 23.6 \u00b0C. The same dataset records extremes of 42.8 \u00b0C (May) and 2.7 \u00b0C (January), so heatwaves and cold snaps do happen.<\/p>\n

Hanoi’s four seasons in plain words<\/h2>\n

Winter: December to February<\/h3>\n

Cool and mostly dry. Daytime highs sit around 20\u201322 \u00b0C and nights drop to about 14\u201316 \u00b0C. Cold air from the north arrives in waves, several times a month, so a mild week can turn chilly overnight. December is the driest month by rainy days (about five). Later in winter the sky is often grey with light drizzle rather than real rain, and February is one of the least sunny months of the year.<\/p>\n

Spring: March and April<\/h3>\n

Mild and humid. Highs climb from the mid-20s to the high 20s \u00b0C. March has the most rainy days of the cool months but very little total rain: it is mostly drizzle and mist, and sunshine is at its lowest. This is also the season of n\u1ed3m<\/em> (see below).<\/p>\n

Summer: May to September<\/h3>\n

Hot, humid and wet. Average highs are 32\u201335 \u00b0C, June is usually the hottest month, and nights stay around 25\u201327 \u00b0C. These five months bring most of the year’s rain, with August the wettest on average. Summer is also the sunniest season, so plan for both strong sun and heavy rain.<\/p>\n

Autumn: October and November<\/h3>\n

Temperatures and rainfall both fall. October is still warm (around 30 \u00b0C by day) with some rain; November is milder, with about 61 mm of rain on around eight days. For us, this is the most comfortable stretch of the year for being outdoors.<\/p>\n

Rainy season and typhoons<\/h2>\n

Vietnam’s tropical cyclone season is generally considered to run from June to November, with the most activity from July to October. Storms tend to move from north to south through the season, so the north is usually affected earlier. On average around two tropical storms a year affect the northern delta and midlands, where Hanoi sits, and September has historically had the most landfalls in Vietnam.<\/p>\n

What this means in practice: most summer days in Hanoi are hot with a shower or two, not storms. A travel publisher that covers north Vietnam describes the storms that matter as usually one or two a year, bringing a day or two of hard rain and wind. The worst effects are usually felt in the mountains: in September 2024, heavy rain from Typhoon Yagi triggered a deadly landslide near Sapa.<\/p>\n
