Flood
Jannali faces a moderate risk of flooding, primarily from heavy rainfall events and potential overflow from nearby waterways. The risk is expected to increase with climate change due to more intense rainfall.
Bushfire
Jannali has a moderate bushfire risk due to its proximity to bushland areas. Hot, dry conditions during the bushfire season can increase the likelihood of fire.
Heat
Jannali is likely to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations, such as the elderly and those with pre-existing health conditions.
Storm
Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds

Climate Safety Analysis

Jannali in New South Wales has an overall climate safety rating of Medium. This multi-hazard assessment combines flood, bushfire, heat, coastal, and storm risk data with climate projections to 2050 from CSIRO and the Bureau of Meteorology.

Key factors affecting Jannali's climate safety include heat, flood. Each hazard is assessed independently and combined for an overall picture. Australia has warmed by approximately 1.5 °C since 1910, with flow-on effects to fire weather, extreme rainfall, and heatwave frequency.

Climate safety for property in Jannali is not uniform — it varies by address. Factors such as elevation, distance to waterways, proximity to bushland, and local drainage all influence actual risk at a specific property. Two nearby properties can have materially different risk profiles.

For a complete property-specific climate safety report for Jannali including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.

Jannali (postcode 2226) is tracked in ClimateNest's suburb hazard model, which maps the share of the suburb's land exposed to each hazard at high and moderate levels. The suburb's highest high-risk exposures are bushfire (21.9% of land in high-risk zones), extreme wind (6.2% of land in high-risk zones), riverine flood (5.8% of land in high-risk zones). Exposure is not uniform across Jannali — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
