February in Thủ Đức, Vietnam, brings average daily highs of 32°C and overnight lows of 24°C in the 2016–2025 historical record.

In the record, at least 1 mm of rain or snow falls on 3 of 28 days on average, a daily chance of 10%. Rain has been relatively infrequent in this record, which leaves more scope for an outdoor plan.

The calculated day length, sunrise to sunset, averages about 12 hours. Sunshine averages 11 hours a day. Use the daylight window to plan the length of excursions, and check local sunrise and sunset times for the dates of your stay. Sunshine is a separate measure, and those hours need not arrive in one uninterrupted stretch.
For time in town, cluster a few stops together and leave the rest of the day open. Check transport and opening hours for any plans that run late.
