Mixed Charts: Climate Rainfall and Temperature Report (Band 9)
Band-9 Task 1 mixed-chart report on rainfall bars plus temperature line, with dual-axis technique and climate vocabulary.
The bar chart shows average monthly rainfall and the line graph shows average temperature in a tropical city. Summarize the information by selecting and reporting the main features.
A Band-9 model report
The visuals pair monsoon rainfall against year-round heat, revealing a climate of constant warmth with violently seasonal rain.
Overall, temperatures hover between 27°C and 32°C all year while rainfall swings from near-drought to deluge. Heat is permanent; water arrives in a four-month burst.
Rainfall divides the year cleanly. November through February average under 50mm monthly — January driest at barely 20mm — before March climbs past 100mm. The monsoon proper runs June to September, peaking in August near 350mm, roughly seventeen times January's total. October retreats sharply to 120mm, closing the wet window.
Temperature, by contrast, barely moves. April peaks at 32°C just before the rains, while December bottoms at 27°C — a five-degree annual range that temperate readers might envy. Notably, the hottest month precedes the wettest by four months: peak heat builds before monsoon clouds cool the city to a still-sweltering 29°C.
The relationship is inverse at the extremes: maximum rain coincides with moderated heat, minimum rain with peak temperatures. Water, not warmth, defines this city's seasons — twelve months of summer divided by flood and dryness.

Examiner notes: why Band 9
Task Achievement (9): Overview contrasts permanence (heat) vs seasonality (rain) before detailing each visual. Bars-then-line structure with a synthesis paragraph linking them.
Coherence & Cohesion (9): Rainfall paragraph (dry/build/monsoon/retreat), temperature paragraph (peak/trough/lag), relationship close. "By contrast," "notably" guide cleanly.
Lexical Resource (9): Climate precision: "deluge," "monsoon proper," "retreats," "sweltering," "annual range," "inverse at extremes." Vivid yet formal.
Grammatical Range & Accuracy (9): Parenthetical figures, concessive clauses, colon-led findings. Exact.
High-scoring phrases
- violently seasonal — extreme variation
- permanent heat, burst water — contrast framing
- wet window — rainy period (concise phrase)
- temperate readers might envy — audience-aware aside
- seasons by flood and dryness — water-defined calendar
- twelve months of summer — memorable summary close
Quick answers
Two data types at once: how do I split them?
One paragraph per visual: bars first, line second, then one synthesis sentence linking them. Separation plus synthesis is the mixed-chart formula.
Should I link the two datasets?
Yes, briefly: rainfall peaks as temperatures dip. One correlation sentence shows insight; the task rewards noticing relationships.
