Henley Weather Forecast & Warnings (2111)

Climate and Geography of Henley

Henley is a small suburb located within the Northern Sydney region, positioned on a peninsula between the Parramatta River and Tarban Creek. Its geographical location at a latitude of approximately 33 degrees south places it within a humid subtropical climate zone. This proximity to significant water bodies provides a slight tempering effect on summer extremes compared to suburbs further west, though humidity remains a frequent factor during the warmer months.

Seasonal Weather Patterns

Spring and autumn often provide the most stable conditions for the area, characterised by mild temperatures and lower humidity levels. During winter, Henley can be subject to cold fronts moving up from the Southern Ocean, though the local topography and coastal proximity often keep overnight minimums slightly higher than those recorded in the Sydney basin interior. Rainfall is generally spread throughout the year, with a slight peak in the first half of the calendar year due to moist easterly flows.

Regional Weather Risks

Being part of the New South Wales coastal fringe, Henley is susceptible to East Coast Lows. These intense low-pressure systems can bring sustained gale-force winds and heavy rainfall over short periods, leading to localised drainage issues and rising river levels. During the summer months, the primary concern shifts to severe thunderstorms. These cells often develop in the heat of the afternoon and can move rapidly across the metropolitan area, occasionally bringing hail and damaging wind gusts. Residents also monitor the bushfire season, as smoke from the larger national parks surrounding the Sydney basin can affect air quality in Henley during dry, hot northerly wind events.
