I was 12 years old in 1976 and remember the heatwave well. Looking online, it appears that there were 15 consecutive days where the temperature reached 32C or higher. What I do remember, is that our village pond (which we called 'The Pool' and was about 200 metres away), totally dried up and it's base was just dried, cracked mud. The Government of the day, appointed a 'Minister of Drought'. That night (or very shortly after), the heavens opened and the next morning, 'The Pool' had flooded it's banks (along with flooding across the country). Probably the most effective Minister ever appointed.
