Daily ERA5 maximum and minimum air temperatures at the requested Sydney grid were averaged by calendar month across 2015–2024. Wet days count daily precipitation totals of at least 1 mm; each value is the average calendar-month count across those ten years. Open-Meteo serves ERA5 on an approximately 0.25° grid; the returned grid point (-33.75, 151.00) differs from the requested coordinates. These are model reanalysis averages, not local station normals or forecasts. Calendar labels follow the Southern Hemisphere seasons and Tourism Australia’s summer guidance. Holiday periods and the Sydney New Year’s Eve event can draw visitors, but these labels are not occupancy or crowd measurements.

Before you travel
Entry, health and insurance advice depends on your passport, trip and home country. Recheck official information before departure.
Depends on passport and travel purpose
International visitors need a valid passport and the correct Australian visa or electronic travel authority before travel; eligibility and application route depend on nationality and purpose. Australian citizens should check passport validity and airline requirements.
Check your own cover and medicines
Visitors generally need to arrange their own medical cover; reciprocal arrangements vary by country. Check medicine import rules and personal health guidance. A condition-specific or reciprocal Medicare entitlement should be confirmed directly.
Check warnings and event changes
For summer outdoor plans, check official heat, fire, surf and severe-weather warnings; event transport can also alter routes. Review current state warnings and insure medical care, cancellation and transport disruption for your itinerary.
Visa conditions, stay length, transit and entry permissions vary by passport and travel purpose. Australian citizens have different requirements. Use official Home Affairs and Border Force information, and confirm rules for transit countries.
Checked 29 October 2026. Recheck the linked authorities before departure. Health guidance is general; individual advice comes from a qualified health professional.

Four Seasons lists a heated outdoor pool. Adina Bondi lists a semi-outdoor pool without a heating statement; Hotel Harry does not list a pool. Confirm operation and access for your dates.
Conditions vary by day. Swim between the flags where lifeguards are operating and follow current warnings and surf conditions.
