🎾 Court Conditions
Loading…
Estimates from recent rain, temperature, humidity and pressure (Open‑Meteo), not official readings. Tournament officials decide when courts are playable, when roofs close and when heat or lightning policies apply.
⌚ Best Time to Play
The Play Index (0–100) scores each hour from temperature and heat index, wind and gusts, rain chance and amount, lightning, UV and humidity, with extra weight on rain for clay and grass. It works for any court: search your own town or tap “Near me.”
🗓️ Tournament Calendar
Dates still to be announced
Dates come from the official 2027 ATP and WTA calendars and 2026 tour pages, researched October 2026. “Official dates” matches the published calendars; “Approx. dates” means the week is right but a start or end day can differ by a day or so. Calendars change, so confirm with the tournament before you travel.
📘 How Weather Affects Tennis
Rain, covers, roofs and how fast each surface dries
Play stops as soon as rain wets the lines. Hard courts dry fastest: staff squeegee and blow the water off, and play often resumes in about 20–45 minutes after the rain ends. Clay soaks up water, becomes slick and heavy, and needs rolling and brushing, so delays run hours and tournaments sometimes cancel the day. Grass is slippery when damp and recovers slowly, so grass events lean on covers and roofs (Wimbledon’s Centre and No. 1 courts have roofs). Retractable roofs (Australian Open, Roland-Garros, Wimbledon, US Open, Madrid and others) let the show courts play through rain, but outer courts stay exposed. Indoor events aren’t affected by weather at all.
Heat and extreme-heat policies
Hot, humid conditions are the biggest health risk in tennis. Grand Slams use heat measures (the Australian Open’s Extreme Heat Policy, the US Open’s Extreme Weather Policy, Wimbledon’s heat rule) that can allow a 10-minute break between sets, close a roof or suspend play on outer courts. They go by a combined heat index (temperature, humidity, sun and wind), not air temperature alone. We flag a “feels like” of about 95 °F (35 °C) as hot and about 103 °F (39 °C) as extreme. Whether and when a policy applies is the tournament’s decision.
Wind
Wind is the most annoying element for tennis. It disturbs the toss, pushes the ball off line and makes one end play like an uphill climb. Steady wind of 10–15 mph begins to change tactics (more slice and topspin, higher margins) and gusts above about 25 mph make serving hard. Wind swirls inside open stadiums, so the flag on the roof isn’t always the wind you feel on court.
Air density, altitude and how the ball flies
Thin air (high altitude, heat or low pressure) means less drag, so the ball flies faster and bounces higher; dense air (sea level, cold, high pressure) slows it and keeps it low and heavy. Madrid (about 650 m up), Bogotá (about 2,600 m) and Guadalajara (about 1,550 m) play notably quicker than courts at sea level. Our “Ball flight” card calculates air density from live temperature, humidity, pressure and altitude and compares it with standard sea-level air (1.225 kg/m³).
Lightning, cold and sun
Most tournaments suspend play when lightning is within roughly 8–10 miles and wait about 30 minutes after the last strike. Cold air (below about 50 °F / 10 °C) makes the ball dead and the court feel slow; bright low sun can cause glare when serving. UV is highest around midday, so day sessions are the sunburn sessions.
How the Play Index works
The Play Index starts at 100 and subtracts for: “feels like” temperature outside roughly 60–82 °F (more for heat), wind gusts over about 12 mph, rain chance and rain amount (more on clay and grass), humid heat, and high UV. Lightning scores 0. Great is 80+, Good 65+, Fair 45+, Poor 25+, and below that is unplayable. It’s a guide for everyday players and a rough outlook for tournaments, not an official ruling.
✉️ Daily Tennis Weather Email
A short briefing for your court or tournament every morning at 6:00 AM local time. Free, and you can unsubscribe anytime.
We’ll send the daily briefing for your current location; choose a different tournament or town above first if you’d like another location. Unsubscribe anytime from the link in every email.
We never sell your data. See our Privacy Policy and Do Not Sell My Data form.
🔒 Privacy Policy
Effective date: October 20, 2026
Tennis Weather (“the site,” “we,” “us”) is operated by Planet Dynamic Networks LLC. This policy explains what information the site collects, how it’s used, and who else sees it. If you have questions, contact us at planetdynamicnetworks@outlook.com.
The short version
- This site does not use advertising trackers, cookies, or analytics. If that ever changes, we’ll update this policy first.
- Your searched or device location is used only to fetch weather data for you (and, if you allow location access, to open the tournament closest to you). It’s sent directly from your browser to the services listed below, not stored on our servers.
- If you subscribe to the daily email briefing, we store the profile information you provide (your name, email address, postal code, and region) so we can send it and know a bit about who we’re writing to.
- We do not sell your data. If you separately check the optional box agreeing to occasional emails from ad partners, we may share your information with those partners for that purpose only; you can withdraw that permission anytime on the Do Not Sell My Data form below, whether or not you ever checked it.
Location data
When you search a place, pick a tournament, or use “Near me,” your browser sends that location directly to public weather and mapping services (listed below) to fetch current conditions, radar, alerts and forecasts. We don’t log or keep your location history; each request happens live in your browser for that page view only. If you subscribe to the daily email, the location shown on the page at that moment is saved with your subscription so we know which forecast to send.
Daily email briefing & your profile (optional)
If you subscribe, the form asks for your name, email address, postal code, and region. We store this together as your subscriber profile. We use it to:
- Send your confirmation email and daily 6 AM local-time briefing
- Let you unsubscribe via the link included in every email
- Understand our subscriber base in aggregate so we can improve what we cover
Emails are sent from planetdynamicnetworks@outlook.com. You can unsubscribe at any time using the link in any briefing email; your address is removed from future daily sends immediately.
Ad partner emails (separate, optional consent)
The signup form has a second, separate checkbox asking whether it’s also OK to send you occasional emails from ad partners. This is never required to get the daily briefing. If you check it, we may share your subscriber profile with those partners for that purpose. If you leave it unchecked, or later change your mind, we do not share your data for this purpose. Use the Do Not Sell My Data form to withdraw it at any time.
We do not sell your data to anyone, under any circumstance.
Weekly internal report
Once a week, a table of current subscriber profiles is emailed internally to planetdynamicnetworks@outlook.com for record-keeping and to track opt-outs. This is an internal operational report, not a third-party disclosure.
Contact / email inquiries
If you email us through any “Contact Us” link, we receive whatever you choose to include in that email (your address, name, and message). We use it only to respond to your inquiry.
Cookies and tracking
This site does not use cookies, advertising trackers, or analytics services. We don’t build a profile of you or track you across other websites. Choices such as units and court surface are kept only in the page’s memory for your visit, and the install-as-app prompt remembers a dismissal in your browser’s local storage on your own device.
Links to tournament websites
The tournament calendar links to each event’s own website or to the ATP and WTA tournament pages. We don’t pass them any information about you. Once you open one, that site’s own privacy policy and terms apply.
Third-party services this site relies on
To provide weather and mapping features, your browser communicates directly with the public services below when you use the site. Like any website you visit, each of them can see your IP address and operates under its own privacy practices, which we encourage you to review if you have concerns:
| Service | Used for |

| BigDataCloud | Converting your coordinates to a place name |
| Google Fonts | The typefaces used on the page (Google can see your IP address when they load) |
| unpkg | Delivers the open-source Leaflet map library the maps run on |
Children’s privacy
This site is not directed at children under 13, and we do not knowingly collect personal information from children.
Changes to this policy
If this policy changes, we’ll update the effective date above. Continued use of the site after a change means you accept the updated policy.

🚫 Do Not Sell My Data
Effective date: October 2026
The short version: we don’t sell your data, ever, to anyone. What we do have is one optional setting (occasional emails from ad partners) that’s separate from the daily weather email and off by default unless you checked it. This form lets you turn that off (or confirm it’s already off), whether or not you’re a current subscriber.
What this covers
When you sign up for the daily email on Tennis Weather, the form asks for your name, email address, postal code, and region. There are two separate consent checkboxes on that form:
- Daily weather email: required to subscribe; this is the core service.
- Occasional emails from ad partners: optional, unchecked unless you explicitly checked it. If you did, we may share your subscriber profile with those partners for that purpose only.
Submitting the form below permanently clears that second consent for the email address you enter, and logs the request so it’s honored even if you sign up again later and accidentally leave the ad-partner box checked.
Opt out now
Enter the email address you signed up with (or any address, if you just want to make sure it’s never shared).
This does not unsubscribe you from the daily weather email; that has its own unsubscribe link in every briefing.
What we never do
We do not sell, rent, or trade your personal information to any third party, under any circumstance, regardless of what you choose above. There is no “sale” of data happening on this site to opt out of in the first place; this form exists so the choice about ad-partner emails is explicit and easy to reverse, not because we’re compensated for sharing your information.
Other ways to reach us about this
You can also email planetdynamicnetworks@outlook.com with the subject line “Do Not Sell” and the email address to opt out; we’ll apply it manually the same way. For the full picture of what we collect and why, see the Privacy Policy.
