Does Starlink work in snow?

Yes. Starlink says its system is “designed to operate reliably in winter conditions, including snow and ice.” Every current kit has a feature called Snow Melt: the dish uses the power it draws to warm its own surface, so snow that lands on it melts or slides off.

What Snow Melt cannot fix is snow that buries the dish or builds up around it. Starlink’s support page says heavy snow that completely covers the dish “may cause intermittent connectivity or temporary loss of service,” on both fixed and motorized models. Where you mount the dish matters as much as the heater.

Quick summary, per Starlink’s help center and spec sheets:

• Light snow and ice: Starlink says light ice buildup or icicles generally do not affect performance.
• Steady snowfall: Snow Melt handles it up to the rated rate for your kit (table below).
• Snow drifts or a buried dish: this can interrupt service. Mount higher.
• Extreme cold: most kits are rated down to -22°F.

How does the Starlink snow melt feature work?

The dish warms its surface using the electricity it already draws. Starlink says this reduces service impacts during snowfall and minimizes the need for manual snow removal. You do not need to buy anything extra.

Snow melt settings in the Starlink app

Open the Starlink app and go to Settings, then Starlink, then Snow Melt. Starlink describes three modes:

If you are on a battery or solar setup in winter, Off saves power but leaves snow to pile up. Automatic is the middle ground.

How fast can Starlink melt snow?

Each Starlink spec sheet lists a snow melt rate. Higher-power kits melt faster. Starlink’s spec sheets give these figures:

Notes: Starlink’s power figures are averages measured at the AC outlet and include the dish, router, power supply and cables. The Mini spec sheet lists an average of 25 to 40 W, slightly different from the support page’s 20 to 40 W. The Performance durability guide says melt rate depends on snow density: 3.5 inches an hour for snow at 100 kg per cubic meter and 5.2 inches an hour for lighter, fluffier snow at 68 kg per cubic meter. In other words, denser snow melts off more slowly than light, fluffy snow.

If snow falls faster than your kit’s rate for long enough, it can stay on the dish. A Mini will fall behind sooner than a Standard or Performance kit in a heavy storm.

Can heavy snow or snow buildup block Starlink?

Yes. Starlink needs a clear view of the sky because the satellites it connects to are always moving overhead. Starlink’s obstruction guidance says a tree branch, pole or roof can cause a service interruption, and its weather page says to install Starlink where “snow buildup and other obstructions do not block the field of view.”

Snow causes trouble in two ways:

1. Snow on top of the dish. Snow Melt handles normal snowfall. A dish completely buried by heavy snow may lose service, Starlink says.
2. Snow around the dish. A plow pile, a drift or a roof edge that loads up with snow can block part of the sky even if the dish itself is clear. Snow Melt does nothing about this.

Motorized (Standard Actuated) dishes have one more winter issue. Starlink says ice or snow around the base can occasionally stop the motors from repositioning the dish, and you may see a “motors blocked” alert in the app. Gently clearing ice or icicles around the base may let it move again.

Should you brush snow off Starlink?

Usually you do not need to. Snow Melt is meant to replace manual clearing. But Starlink says that if you choose to remove snow or ice, you may do so gently at any time.

Starlink’s do’s and don’ts:

• Do remove snow gently, by hand or with something soft, if you want to.
• Do not use picks, chisels or scrapers. Starlink says these can damage the dish.
• Do not put a cover over the dish. Starlink says a cover degrades performance, including its ability to melt snow.

Starlink’s pages do not mention hot water, salt or de-icing sprays, so this guide does not recommend any of them.

If your dish is on a roof, stay off the roof in snow and ice. Getting the dish back online is not worth a fall. If it is buried often, move it somewhere you can reach from the ground, such as a pole. For clearing snow around the house safely, see how to shovel snow safely, and for roof loads, see how much snow a roof can hold.

Where should you mount Starlink in snowy areas?

Starlink’s installation guidance points the same direction for snow country:

• Mount higher if possible. Starlink’s install page says mounting higher reduces blockages, and its mount guidance suggests a roof, pole or wall when you cannot get a clear view from the ground.
• Avoid spots where snow will bury it. Starlink recommends a location where the dish is unlikely to be buried or see significant snow buildup. That rules out the ground next to a driveway that gets plowed, and low spots that collect drifts.
• Use the app’s alignment tool first. Starlink says to check the view of the sky with the app before drilling or clamping.
• Use the right mount for your kit. Starlink says its mounts are specific to each kit and not cross-compatible. The Mini kit includes a pipe adapter for poles between 1.25 and 2 inches in diameter.
• Mind the angle on Performance kits. Starlink says Performance (Gen 2) is designed to sit at 8 degrees on a horizontal surface to help prevent rain or snow buildup, and its Performance durability guide recommends a wedge, wall or pipe mount so water sheds from the surface.

A ground-level kickstand setup is fine for testing. For a full winter, Starlink says many customers find a permanent mount gives the best service.

Does snow or rain slow Starlink down?

Sometimes. Starlink says that in extreme cases, heavy rain or wind may slow your connection or cause a rare outage, and that heavy snow covering the dish can cause intermittent connectivity. It also says Starlink may have slightly lower performance during extreme heat or cold.

Starlink does not publish a percentage for how much a storm slows it. If your household needs steady speeds for video calls or remote work, check your plan’s speed against how much internet speed you need. If wired service is available at your address, fiber vs. cable internet covers what those options offer.

How cold can Starlink get?

Starlink’s weather page lists these operating ranges:

The Performance durability guide says all Performance products are qualified to work at -40°F “without impact to performance.” The indoor range for the router and power supply is the one people overlook: do not leave them in an unheated shed or garage that drops below freezing.

How much power does Starlink use in winter, and what about outages?

Starlink lists average power use by kit (table above) and says it varies with temperature, location and use. Its Performance durability guide says power draw at lower temperatures increases when snow melt is active. Starlink does not publish a separate winter wattage for Standard or Mini kits, and Pre-heat mode may add more.

Our math for a day of use at Starlink’s listed averages:

• Standard 4: 75 to 100 W x 24 hours = 1.8 to 2.4 kWh a day
• Standard Actuated: 50 to 75 W x 24 hours = 1.2 to 1.8 kWh a day
• Mini: 20 to 40 W x 24 hours = 0.48 to 0.96 kWh a day

Expect the high end, or more, during snowy weather.

Power outages. Starlink cannot work without electricity, so a winter blackout takes your internet down with it unless you have backup power. Starlink recommends powering the dish and any router from a UPS-protected outlet to avoid surges, brownouts and reboots that can cause 10+ minute outages.

For runtime, divide battery capacity by draw. Our estimate: a 1,000 Wh power station running a Standard kit at 100 W lasts at most 1,000 / 100 = 10 hours, and less in practice because of conversion losses. A Mini at 30 W could run up to about 33 hours on the same battery. Size a backup with our UPS battery backup sizing guide or the power station size calculator, and see winter power outage preparation for the rest of the house.

Starlink also says that for lightning storms, or when the system will sit unused for a long time, unplugging it from the wall outlet and disconnecting the Starlink cable may prevent damage from lightning and power surges.
