The precipitation increases steadily from around 25 mm in the first 2 months to about 100 mm in March, after which it begins to soar until April when it peaks at 280 mm. The precipitation tends to decrease in later months with a dramatic drop to as low as 20-30 mm from Jun to Sep. However, in the next 2 months, the graph shows an opposite trend with an increase to around 150-160 mm, followed by a decrease to 50 mm in Dec which is just one third as high as it is in Nov.

Compared to the monthly precipitation, temperature witnesses a more modest fluctuation. From January to March, there is a gradual climb of temperature from 22 °C to just above 30 °C which is its maximum figure. The temperature starts to decline after March with a relatively gradual decline to the lowest point of 20.5°C in July. The tendency is more obvious between Aug and December when it backs to the figure in January.

All in all, in January and December, both precipitation and temperature are low, and from June to September, the numbers are the lowest.

Overall, precipitation shows significant seasonal variation, peaking sharply in spring and reaching its lowest levels in mid-year, whereas temperature changes are comparatively moderate throughout the year.

Precipitation rises steadily from approximately 25 millimetres in January and February to around 100 millimetres in March, before increasing dramatically to a peak of about 280 millimetres in April. After this point, rainfall declines substantially, falling to its lowest range of roughly 20 to 30 millimetres between June and September. In the following two months, precipitation rebounds to around 150–160 millimetres, before dropping again to approximately 50 millimetres in December, which is roughly one third of the figure recorded in November.

⚠️ Hạn chế:

Overview chưa thật sự rõ ràng (nên tóm tắt xu hướng chính ngay đầu hoặc cuối đoạn)
Câu kết “from June to September, the numbers are the lowest” chưa chính xác hoàn toàn vì nhiệt độ không phải thấp nhất trong toàn bộ giai đoạn này

Lỗi ngữ pháp nhẹ nhưng lặp lại:
from Jun to Sep → giới từ + viết tắt
which is just one third as high as it is in Nov → cấu trúc so sánh chưa chuẩnDấu cách không thống nhất: 20.5°C vs 22 °C

Một số liên kết còn hơi “nói”:
Lặp cấu trúc “the graph shows”
Dùng however hơi nhiều

Lỗi / chưa học thuật:
backs to the figure ❌ → nên là returns to
Jun, Sep, Dec ❌ → nên viết đầy đủ: June, September, December
as high as it is in Nov → nên là as high as that in November

✅
