Hydration in the Local Climate: How Much and What to Drink on the Central Coast

Central Coast surf clubs and bushwalking groups are calling on locals to pay closer attention to their hydration as unseasonably warm July days coincide with peak outdoor activity. Gosford Hospital’s emergency department recorded a 14% increase in dehydration cases last June, a trend staff worry could worsen this month.

Why Staying Hydrated Matters Now

After a mild but drier-than-average winter, the Bureau of Meteorology reports the Central Coast is facing higher-than-usual maximums. With the region’s coastal humidity and brisk westerlies, dehydration can happen before residents notice the signs. Local hiking guides say Bouddi National Park tracks are particularly busy on weekends, and with the school holidays in full swing, young families and groups are venturing further afield. The risk is not confined to athletes—elderly walkers on the Gosford-to-Terrigal path and even office workers on Mann Street are being urged to reassess how much and what they drink.

At Avoca Beach Surf Life Saving Club, Director Mark Stokes confirmed they have doubled their water station refills since the Queen's Birthday weekend. Meanwhile, Terrigal Trotters, the local running and cycling club, updated their pre-event advice last month to include reminders about hydration and electrolyte replacement, especially for the weekly Sunday rides around Tuggerah Lake. Club organisers say participants have complained of cramping and fatigue, only to realise their Saturday night habits didn’t include enough water or appropriate fluids the day before.

How Much, What Kind and What It Costs

Australian dietary guidelines recommend that adults drink around 2.6 litres of water per day for men and 2.1 litres for women, but local GPs such as Dr. Alice Nguyen at Erina Family Medicine stress that needs vary based on activity and climate. Central Coast weather often fools residents—the sea breeze can mask both thirst and sweat loss. Terrigal Medical Centre nurses say most outpatient heat illness cases report drinking less than a litre during full outdoor days, particularly among teens playing after-school soccer on Duffys Road Oval.

Electrolyte drinks are gaining popularity here, particularly among cyclists and surfers. At the Terrigal Beach Coles, a 600-millilitre bottle of Powerade now retails for $3.50, compared to the local tap water—free to refill at public fountains along the Esplanade and on the new Terrigal Haven-to-Lagoon Beach walk. However, sports dietitians caution against overdoing sugary beverages, suggesting simple sodium tablets or coconut water for most low-to-moderate activity.

To bridge the knowledge gap, Central Coast Health will set up free community hydration checks and water bottle giveaways during the Sunday Riverside Park Market at Gosford on July 13. Information leaflets will detail warning signs for dehydration—such as dizziness, confusion, and dark urine—as well as tips on safely hydrating before, during, and after activity.

Practical changes are easy: Carry a reusable water bottle, make use of public refill stations, and consider flavouring water with fresh citrus or herbs for taste without the sugar. Both the Avoca Beach surf club kiosk and Terrigal runners’ pop-up tent now keep jugs of chilled cucumber-lemon water for anyone in need. If in doubt, locals are urged to seek advice from their GP or Central Coast dietetic services before starting any new hydration or supplement routine. The message is clear: in the Central Coast’s sneaky winter sun, keeping your water intake up can be as important as your morning coffee or sunscreen.
