Neco 2022 Geography Question 39

The following climate data are recorded for a location: average monthly temperatures (°C): Jan 28, Feb 30, Mar 32, Apr 34, May 35, Jun 33, Jul 31, Aug 30, Sep 29, Oct 28, Nov 27, Dec 27; average monthly precipitation (mm): Jan 5, Feb 10, Mar 20, Apr 40, May 80, Jun 120, Jul 150, Aug 130, Sep 90, Oct 50, Nov 20, Dec 10. Using the Köppen criteria where (i) all months have mean temperature > 18 °C, (ii) a tropical rainforest climate (Af) requires every month's precipitation ≥ 60 mm, (iii) a tropical monsoon climate (Am) allows a short dry season with at least one month < 60 mm but total annual precipitation > 1 500 mm, and (iv) a tropical savanna climate (Aw) has a distinct dry season with total annual precipitation < 1 500 mm, determine the Köppen climate classification (first two letters) for the location.
