Families prepare for a cricket season by buying gear, sorting out registration and working out training nights. Very few prepare for heat, which is the one thing guaranteed to affect a Melbourne summer and the one issue most likely to cause a genuine medical problem on a Saturday morning.
There is also a widespread assumption that somebody else is handling it, that a club or umpire will call things off if it gets dangerous. That is partly true, and it is worth understanding how it actually works, because the system relies on adults at the ground making judgement calls, and one of those adults is you.
Cricket is hotter than it looks
Watching from the boundary, cricket appears to be a low-intensity sport with plenty of standing around. The physiology says otherwise.
Sports Medicine Australia’s heat guidance treats cricket as higher risk than many activities of similar intensity, for two specific reasons: the protective equipment players wear, and the overall work rate involved. A batter in pads, gloves and a helmet, or a wicketkeeper in full gear, is carrying insulation that traps heat and prevents the body from cooling the way it normally would.
This produces an outcome that surprises parents. The most heat-affected players are often not the ones running around. They are the batter who has been at the crease for half an hour in full equipment, and the keeper who has been crouching in a helmet since the innings started.
Add a long exposure window, since junior cricket runs for hours rather than minutes, and usually in the middle of the day, and the risk picture looks quite different from a quick weekend sport.
The tool most parents have never heard of
Cricket Australia publishes a Heat Stress Risk Index for community cricket, which clubs and officials use to assess conditions. It combines air temperature with humidity and wind rather than relying on temperature alone, because those factors change how the body copes.
The part worth knowing is that there is a separate version specifically for under 18s. Cricket Australia treats junior and adolescent players as needing a more conservative approach than adults, and the junior tool is intended for use in matches, tournaments and training sessions involving players under 18.
That last detail catches people out. Heat guidance is not only a match day consideration. A weeknight training session in February falls under the same thinking.
Specific thresholds and the actions attached to them sit within the tool itself, and individual associations set their own cancellation policies on top, which differ across Melbourne. Rather than working from a number someone mentioned, look up the current heat guidelines on the Play Cricket community resources site and ask your association for its own policy before the season starts.
Who actually makes the call
Responsibility for applying heat protocols generally sits with club representatives, association officials or match officials, depending on the competition. Umpires and captains are expected to assess whether conditions are fit for play and to suspend play if they are not.
In practice, decisions get made by whoever is paying attention. A parent who notices their child is struggling and says something is not interfering; they are doing exactly what the system depends on. No official has ever been criticised for taking a child off the field too early.
What to watch for in your own child
Heat illness develops gradually, and children are notoriously poor at recognising it in themselves, partly because they do not want to come off. Signs worth knowing:
- Muscle cramping, particularly in the legs.
- Dizziness, headache or complaints of feeling unwell.
- Fatigue that seems out of proportion to what they have been doing.
- Nausea, or a child who has gone quiet and withdrawn when they are normally vocal.
- Skin that looks flushed, or unusually pale and clammy.
A child showing these signs should come off, get into shade, and start cooling and rehydrating. If symptoms include confusion, vomiting, or they do not improve with rest and cooling, that needs medical attention rather than a wait-and-see approach.
Hydration that actually works
The most common mistake is starting hydration at the ground. A child who arrives already behind will not catch up during a match, because the body absorbs fluid at a limited rate.
Drinking steadily through the day before and the morning of a match matters more than the bottle they carry. During play, regular small amounts beat large volumes at drink breaks. Freezing a bottle overnight gives cold water for longer, which children drink more of. These habits sit alongside the broader nutrition principles that support young athletes, where the fundamentals matter far more than any product.
Sports drinks are generally unnecessary for junior cricket. Water plus normal meals cover it for the durations involved.
What to pack and wear
A wide-brimmed hat for fielding, sunscreen applied before arriving and reapplied at the break, a spare shirt, and more water than seems necessary. Light coloured, loose and breathable clothing makes a real difference over several hours, which is one reason the right cricket clothing choices affect comfort and performance rather than being purely cosmetic.
Shade is worth thinking about in advance too. Many suburban grounds in the northern growth corridor are new, which often means young trees and very little natural shade. A folding chair under a gazebo is not indulgent; it is the only shade some grounds have.
Training through a hot week
Bowlers deserve particular attention in heat. Bowling is the highest intensity activity on the field and fatigue affects technique, which in turn raises injury risk. On hot days, shortening spells is sensible on top of the usual junior pace bowling workload guidelines, rather than treating the two as separate considerations.
For the handful of genuinely extreme days each summer, moving training indoors is the straightforward answer. This is one of the practical arguments for having both indoor and outdoor options rather than relying entirely on one, since consistency through January and February is what carries a player into the second half of a season.
Heat is manageable with a bit of planning. It becomes a problem when everyone assumes someone else is watching.
FAQs
Who decides whether a junior match goes ahead in extreme heat?
It depends on the competition, but responsibility usually sits with club officials, association administrators or the umpires and captains at the ground. Many associations also set a forecast temperature at which play is cancelled outright, and these thresholds differ across Melbourne. Ask your association for its specific policy at the start of the season rather than trying to find out on a hot Saturday morning.
Is my child too young to be playing in the heat at all?
Younger players are treated as requiring more caution, which is why a separate junior heat tool exists. Very young children are considered particularly vulnerable, partly because they are less likely to recognise or act on warning signs. This does not mean avoiding summer cricket; it means adult supervision has to be more active than it would be for an adult team.
My child says they are fine but looks terrible. Who do I believe?
Believe what you can see. Children routinely underreport how they are feeling during sport, especially if coming off means letting the team down or missing a turn to bat. If a child looks unwell, taking them off for ten minutes in the shade costs very little and occasionally prevents something serious.
Do the heat guidelines apply to training as well as matches?
Yes. Cricket Australia’s junior heat tool is intended for matches, tournaments and training sessions for under 18 players. A hot weeknight session in midsummer warrants the same consideration as a match, which is something many families and some clubs overlook.
What should be in the kit bag specifically for hot days?
Extra water beyond what seems necessary, a wide-brimmed hat, sunscreen, a spare shirt and a towel that can be wet down for cooling. If your child keeps or opens the batting, factor in that they will be in equipment for long stretches, so a way to cool down quickly between innings matters more for them than for the rest of the team.

Melbourne summers produce a handful of days each season where outdoor training is genuinely unwise. A climate-controlled indoor centre means a session does not have to be cancelled or pushed through in conditions that are not safe for a child. If you want to keep your child training consistently through the hottest weeks, call 1300 310 769 or email info@conceptsports.com.au and we will find a time that works. Our centre is at 1/16 Poa Court, Craigieburn VIC 3064. More at conceptsportsacademy.com.au. |
