Worst month for Ipoh — heat or monsoon?

Worst month Ipoh — March–May hottest dry 35°C+ midday, cave temples brutal after 11am. Oct–Nov monsoon afternoon downpours 1–2 hr, morning caves usually OK. Dec–Jan cooler best weather crowds holidays. Feb Chinese New Year some closures. Heat worse than rain for outdoor — always cave AM, food PM AC cafes. Penang sea breeze cooler — Ipoh inland oven.
