Tennis weather, block by block
Which evening this week should you book the court? BlockCast scores every block of your week for tennis from live rain, wind, feels-like temperature and UV forecasts, so the answer is a green square instead of five weather tabs.
Free. No account, no ads, no tracking. iPhone, iPad and any web browser.
What BlockCast checks for tennis
Every block gets a risk score from 0 to 100: green under 25, yellow under 55, red above. The worst factor drives the score and the others add to it. These are the default weights; you can change any of them in the app under Adjust.
Comfortable feels-like temperature: 10 to 30 °C (50 to 86 °F). Wind adds risk from 20 km/h (12 mph) sustained or 38 km/h (24 mph) in gusts.
How it works
- Pick tennis and your spot. Use your location or search any place in the world, and save up to three.
- Read your week at a glance. Choose 2, 3, 4 or 6 hour blocks and the hours you actually play. Tap any block for the hour-by-hour detail and the reason behind its colour.
- Plan it and stop checking. Add the session to your planner and your calendar. BlockCast re-checks every forecast and tells you if a planned session turns bad.
Tennis weather questions
Can you play tennis after it rains?
A wet hard court is slippery and the lines get dangerous, so even a short shower can cost an hour of drying time. That is why rain carries the full weight of 10 out of 10 for tennis in BlockCast, and why the app takes the wettest of three forecast models before it calls a block green.
How windy is too windy for tennis?
Wind starts to move the toss and the lob at around 20 km/h (12 mph), and gusts make timing unpredictable well before that. BlockCast adds risk from 20 km/h of sustained wind and weighs gusts on their own, so a calm average with a gusty afternoon still shows up.
What temperature is too hot for tennis?
BlockCast scores tennis as comfortable between 10 and 30 °C (50 and 86 °F) of feels-like temperature, which already folds in humidity and wind chill. Outside that band the block turns yellow, then red. Your own limits may differ, and you can move both ends under Adjust.
Where the data comes from
Forecasts come from Open-Meteo. Rain is the wettest of three models (the local best match, ECMWF and Canada’s GEM), so a green block means they all agree. Radar is the North American composite from Environment and Climate Change Canada; official alerts come from Environment Canada and the US National Weather Service.
