On May 2, Dong Nai Hydrometeorological Station forecasted that in May, the weather in the province will be mainly affected by the northern edge of the equatorial low pressure trough, whose axis gradually lifts to the north and becomes stronger. The southwest wind will begin to appear from around May 5 to 6, with weak to moderate intensity. Above, the subtropical high pressure will slightly lift its axis to the north, operating with relatively stable intensity.

The above weather pattern makes the weather in the province sunny during the day, hot in some places, with scattered rain in the evening and at night in some places in the first half of May. From the second half of May, there will be scattered rain in many places, some places will have heavy rain to very heavy rain and thunderstorms. During thunderstorms, be careful of thunderstorms, tornadoes, lightning and strong gusts of wind. Southwest wind level 2, sometimes level 3.
