To keep training through Singapore’s rainy season, plan sessions around the weather instead of against it: move outdoor sessions to the dry window or to an indoor court, stop at the first sign of lightning, and adjust your game for a wet, heavier ball and slower footing when you do play after rain. Most players lose weeks of practice at this time of year because they wait for the weather to clear. A few simple rules keep your training continuous. This guide sets out the rules I use with my players, plus four drills for the days when conditions are less than ideal.
In my coaching sessions, I notice that the weeks after a wet spell are when many players feel their timing has gone. Often the cause is not lost fitness. It is a change in conditions that nobody told them to expect.
How the weather changes your tennis
Singapore has no true dry season. Thundery showers are common through the inter-monsoon months, and the northeast monsoon later in the year brings longer wet spells. For a tennis player, three things change when it rains or has just rained.
- The ball gets heavier and slower. Damp balls absorb moisture, bounce lower and travel through the air less. A shot that normally reaches the baseline can land short.
- The court gets slower and less safe. A damp hard court grips the ball differently, and any film of water or algae makes sudden stops and changes of direction risky for your ankles and knees.
- Your rhythm is broken. Rain delays, short sessions and cancelled lessons all disrupt the repetition that keeps timing sharp.
If you have read my notes on playing in Singapore’s heat and humidity, you will know that humid air already makes the ball feel different. Rain adds another layer on top of that.
Safety first: lightning and wet courts
Before technique, a safety rule. Thunderstorms in Singapore can build quickly, and a tennis court is an open space with metal fencing and a racquet in your hand. I follow the widely used 30-30 guideline with all my groups. If the gap between a flash of lightning and the thunder is 30 seconds or less, go indoors or into a solid building. Do not go back on court until 30 minutes after the last thunder you hear. A parked car or a proper building is safe shelter. A tree or a shelter with open sides is not.
Wet courts need a separate decision. If you can see standing water, or if your shoes slip when you do a gentle split step, the court is not playable. Towel-drying the lines and the area behind the baseline helps, but a court that is still shiny after drying is still too slick for hard stops. Skipping a session costs you one practice. A twisted ankle costs you weeks.
Scheduling around the rain
The best adjustment is the simplest one: be flexible about when you play. Thunderstorms in Singapore tend to be short and local, and mornings are often drier than afternoons in the wetter months. I suggest the following approach.
- Check the rain radar and the forecast on the morning of your session, not the night before.
- Have a fallback plan. If your court is outdoors, know which indoor court or covered space you can switch to at short notice.
- Keep your warm-up portable. A ten-minute off-court routine of skipping, light footwork and shoulder activation lets you start quickly when the rain stops.
- Split a long session into two short ones if a shower interrupts. Two forty-minute blocks are better than a cancelled day.
My article on indoor versus outdoor tennis in Singapore sets out how margin, positioning and timing change when you move between the two, which matters if you switch venues because of the weather.
How to adjust your game on a damp court
Add margin to your depth
A heavier ball does not carry as far, so aim a metre or two deeper into the court than usual and add a little more racquet-head speed through the ball. Players who keep their normal targets will see more short balls, and short balls give opponents a free attack.
Shorten your steps and lower your centre
On a slippery surface, small adjusting steps are safer than long lunges. Bend your knees a little more, keep your weight over the middle of your feet, and avoid big sliding stops. Good split step timing matters more on wet days, because it lets you start each movement from a stable base. If your timing is unreliable, my guide to split step timing explains how to fix it.
Choose patterns that keep the ball in play
A low, slow ball rewards patience. I steer players toward high-percentage crosscourt rallies and away from low-margin down-the-line shots, which I explain in my piece on crosscourt versus down the line. Save the big flat shot for a clearly short ball.
Look after the equipment
Wet strings lose some of their liveliness, and a damp grip becomes slippery. Carry a spare towel and an overgrip so you can change when the handle gets slick. Dry your racquet and shoes after you play, and do not leave your bag in a hot car, because trapped moisture ages grips and shoe soles faster. Rain does not damage strings on its own, but frequent wet play is a good reason to check them against my notes on how often to restring.
Four drills for wet-weather weeks
Drill 1: Shadow footwork on a dry surface
If you cannot get on court, find a dry corridor, a covered car park level or a void deck with enough room. Mark four points with tape and practise split step, push to the first point, recover to the centre, and repeat in random order for 30-second rounds. Five rounds, with a short rest between each, keep the legs ready and the timing active.
Drill 2: Wall or rebound work
Where there is a covered wall or practice backboard, hit controlled forehands and backhands at 70 per cent pace for three minutes, then rest. Count the longest run without an error. The aim is clean contact and consistent depth, not power. This is also a good way to test the changes in your swing that I describe in my forehand diagnostic checklist.
Drill 3: Heavy-ball depth game
When you return to a damp court, mark a target zone one metre inside the baseline with a cone or a line of tape. Rally crosscourt with a partner and score a point each time your ball lands inside the zone. Play to 11. The drill teaches you to add depth when the ball is heavier.
Drill 4: Short-session point play
When showers cut your time, play 15-minute sets of tiebreak points starting from a specific score such as 4-4. Short, high-intensity points keep your match sharpness even when you cannot train for an hour. It also supports the transfer from practice to matches I describe in why you play worse in matches than in practice.
Returning to play after a long wet spell
If rain has kept you off court for a week or more, do not go straight back to full-intensity match play. Start with a longer warm-up, hit at 70 per cent for the first 15 to 20 minutes, and build your pace slowly. Legs and shoulders tolerate sudden spikes in load badly, especially after a break. For juniors, check that the return to training is gradual as well. My guide on how often a junior should train has useful guidelines on load and rest.
Common questions
Is it safe to play tennis in light rain?
Drizzle without lightning is playable on some surfaces, but the ball becomes heavy quickly and the court gets slick. I would stop as soon as you notice your footing change, and I would never continue if there is thunder or lightning.
How long should I wait after rain before playing?
There is no fixed time. The court must be free of standing water and no longer slippery when you do a gentle split step. Hard courts dry faster under sun and wind than in humid, overcast conditions, so check the surface itself rather than the clock.
Should I change my string tension for wet weather?
Not as a rule. Changing your setup for a few wet weeks usually creates more problems than it solves. If your racquet feels dead year-round, that is a separate question, covered in my guide to string tension for intermediate spin players.
What can I do for fitness if I cannot play for several days?
Keep the footwork and conditioning work going off court. Short interval running, skipping, lunges, and shoulder and core exercises maintain the physical base. Add a few minutes of mobility work after each session.
