Staying hydrated in Geelong's climate: How much and what to drink

Geelong's climate presents a unique hydration challenge. Summer temperatures regularly exceed 30°C, while our coastal location means humidity can fluctuate dramatically. Yet many of us underestimate how much fluid we actually need, particularly when exercising outdoors or simply going about our day in the warmer months.

The classic advice to drink eight glasses of water daily is a starting point, but it's not one-size-fits-all. For Geelong residents, especially those tackling the Barwon River walking trail or joining the weekly parkrun at the Geelong Waterfront, individual needs vary significantly based on age, activity level, and whether you're prone to sweating.

A practical benchmark: aim for pale yellow urine as a hydration indicator. If it's dark, you're likely dehydrated. During moderate exercise in our climate—say, a 45-minute walk along the waterfront in summer—most adults need an extra 400–800 millilitres of fluid beyond their baseline intake.

Water remains your best choice, but it's not your only option. Sports drinks containing carbohydrates and electrolytes (sodium and potassium) become valuable during sustained activity lasting over an hour, particularly on hot days. Local cafes around Gheringhap Street and the Waterfront precinct offer both plain water and electrolyte options, though they vary in quality and price—expect $5–$8 for branded sports drinks.

What about coconut water, tea, or coffee? Coconut water provides natural electrolytes and is available at most Geelong supermarkets for around $4 per litre. Tea and moderate coffee consumption count toward hydration, despite caffeine's mild diuretic effect—the fluid intake outweighs any losses. Sugary soft drinks and energy drinks? They're hydrating but pack unnecessary calories and can spike blood sugar.

Timing matters too. Rather than drinking one large volume at once, sipping consistently throughout the day—particularly before, during, and after outdoor activities—helps your body absorb and use fluids more effectively. Before heading to Eastern Beach's rock pool or a summer walk, drink 400–600 millilitres about two to three hours beforehand, then another 200–300 millilitres about 20 minutes before you leave.

Winter in Geelong brings cooler temperatures and lower activity levels for many, yet dehydration still occurs—indoor heating reduces skin moisture, and we often drink less when it's cold. Maintaining consistent hydration year-round supports energy, cognitive function, and overall wellness.

If you have specific health conditions, are pregnant, or take medications affecting fluid balance, consult your GP or a dietitian at Barwon Health for personalised advice. Your body's hydration needs are as individual as Geelong itself.
