1. Types of Extreme Weather Events in Sydney

Sydney experiences a variety of extreme weather events due to its temperate climate and geographical location. These include:

a. Heatwaves

• Description: Prolonged periods of excessively high temperatures, often accompanied by high humidity.
• Frequency: Common during the summer months (December to February), with temperatures occasionally exceeding 40°C (104°F).
• Risks: Heat exhaustion, dehydration, bushfires, and strain on energy systems due to increased air conditioning use.

b. Bushfires

• Description: Fires that occur in bushland areas, often exacerbated by hot, dry, and windy conditions.
• Frequency: Most common during the summer and early autumn (December to March), particularly in areas surrounding Sydney.
• Risks: Property damage, air quality issues (smoke haze), road closures, and health risks for those with respiratory conditions.

c. Severe Thunderstorms

• Description: Intense storms with heavy rain, strong winds, hail, and lightning.
• Frequency: Typically occur in late spring and summer (October to March).
• Risks: Flash flooding, property damage, power outages, and transportation disruptions.

d. Flooding

• Description: Can result from heavy rainfall, overflowing rivers, or coastal storm surges.
• Frequency: Occurs sporadically, often during La Niña weather patterns, which bring increased rainfall.
• Risks: Damage to infrastructure, road closures, and disruptions to public transport.

e. Coastal Storms and Erosion

• Description: Strong winds, heavy rain, and large waves that can erode beaches and damage coastal infrastructure.
• Frequency: Occasional, often during the winter months (June to August).
• Risks: Beach closures, damage to coastal properties, and risks to swimmers and surfers.

f. Cold Snaps

• Description: Sudden drops in temperature, often accompanied by strong winds and rain.
• Frequency: Rare but can occur during winter (June to August).
• Risks: Discomfort for those unprepared for colder weather and increased energy costs for heating.
