The Pre-Run Weather Check: A 2-Minute Routine

The best runners don't just check the weather—they have a system. A quick pre-run weather check prevents surprises and helps you dress right, plan smart, and run better.

The 2-Minute Weather Check

Before Every Run

These five questions take 2 minutes and prevent most weather-related problems:

1. What's the "feels like" temperature?
2. What's the precipitation chance?
3. How strong is the wind?
4. Will conditions change during my run?
5. Is there anything dangerous?

That's it. Answer these five questions and you're prepared.

Question 1: Feels Like Temperature

Why It Matters

"Feels like" combines temperature, humidity, and wind into one number that tells you what it will actually feel like outside.

What to Check

Look for the "feels like," "apparent temperature," or "real feel" number—not the actual temperature.

The Decision

| Feels Like | Quick Decision | |------------|----------------| | Below 30°F | Full winter gear | | 30-45°F | Layers, gloves, hat | | 45-60°F | Long sleeve or layers | | 60-70°F | T-shirt, shorts | | Above 70°F | Minimal clothing, hydration plan |

<QuickTip> Dress for the "feels like" temperature as if it's 15-20°F warmer. You generate significant heat while running. </QuickTip>

Question 2: Precipitation

Why It Matters

Rain changes everything—clothing, safety, enjoyment.

What to Check

• Chance of precipitation - Will it rain?
• Timing - When will it start/stop?
• Intensity - Drizzle vs. downpour?
• Type - Rain, snow, sleet?

The Decision

| Precipitation | Quick Decision | |---------------|----------------| | 0-20% chance | Proceed normally | | 20-50% chance | Check timing, bring layer | | 50-80% chance | Plan for wet run | | Rain already falling | Decide: embrace it or reschedule | | Lightning possible | Do not run outside |

<Callout type="warning" title="Lightning Override"> If there's any chance of lightning, don't run outside. This is non-negotiable—lightning kills runners. </Callout>

Question 3: Wind Speed

Why It Matters

Wind affects effort, comfort, and safety.

What to Check

• Wind speed - How strong?
• Gusts - Are there stronger bursts?
• Direction - Relative to your route?

The Decision

| Wind Speed | Quick Decision | |------------|----------------| | Under 10 mph | Normal running | | 10-15 mph | Expect effort increase | | 15-20 mph | Plan route direction carefully | | Above 20 mph | Consider rescheduling |

Wind Strategy

If wind is significant:

• Start your run INTO the wind
• Return WITH the wind at your back
• This prevents finishing exhausted against headwind

Question 4: Changing Conditions

Why It Matters

Weather at the start may not match weather at the finish.

What to Check

• Hourly forecast - Not just current conditions
• Temperature trend - Warming or cooling?
• Storm timing - When might it arrive?

Common Scenarios

Morning run, warming day:

• Start feeling cool
• May need to shed layers
• Bring removable items

Evening run, cooling day:

• May cool significantly during run
• Consider bringing extra layer
• Plan shorter if temps dropping fast

Storm approaching:

• Time your run to finish before it hits
• Or wait until it passes

<QuickTip> Check the hourly forecast for when you'll FINISH, not just when you'll START. A lot can change in 60-90 minutes. </QuickTip>

Question 5: Danger Check

Why It Matters

Some conditions aren't just uncomfortable—they're dangerous.

What to Check

• Heat index - Above 105°F = danger
• Wind chill - Below -10°F = frostbite risk
• Air quality (AQI) - Above 150 = stay inside
• Lightning - Any chance = don't run
• Severe weather warnings - Take seriously

The Decision

Any of these = don't run outside:

• Heat index over 105°F
• Wind chill below -15°F
• AQI over 150
• Lightning in forecast
• Tornado, flood, or severe weather warning

Building the Habit

Make It Automatic

The check should happen every time:

• Right after waking (morning runs)
• Before leaving work (evening runs)
• While getting ready
• Part of your pre-run routine

Where to Check

Quick checks:

• Phone weather app (already have it)
• Weather widget on home screen
• Run Window app (running-specific)

Deeper checks:

• Weather.gov (US)
• AccuWeather hourly
• Weather Underground

When to Check

The night before:

• Plan tomorrow's gear
• Set expectations
• Identify potential issues

Morning of:

• Confirm conditions
• Final gear decisions
• Adjust if needed

Sample Check Routines

30-Second Quick Check

For routine runs in familiar conditions:

1. Open weather app
2. Note feels-like temp
3. Check precipitation
4. Glance at wind
5. Go run

2-Minute Full Check

For runs where conditions matter:

1. Current feels-like temperature
2. Hourly forecast for run duration
3. Precipitation chance and timing
4. Wind speed and direction
5. Any warnings or alerts
6. AQI (if relevant to your area)

Pre-Race or Long Run Check

For important runs:

1. Multi-day forecast trend
2. Hour-by-hour for race window
3. All factors (temp, humidity, wind, precip)
4. Sunrise/sunset timing
5. Backup plan if conditions change

Common Mistakes

Checking Once, Days Ahead

Forecasts change. A forecast from 3 days ago may be wrong.

Fix: Check again the morning of your run.

Checking Only Temperature

Temperature alone is misleading. Humidity and wind change everything.

Fix: Always look at "feels like."

Ignoring Hourly Changes

Starting conditions may differ from ending conditions.

Fix: Check the full duration of your run.

Skipping the Check Entirely

"It looks fine outside" leads to surprises.

Fix: Make the check a non-negotiable habit.

Adapting Your Plan

Based on Your Check

The weather check should inform:

• What to wear - Clothing choices
• What to bring - Water, layers
• When to go - Best window timing
• How far to run - Adjust distance if needed
• What workout to do - Hard effort vs. easy day

Being Flexible

The check might tell you:

• "Now is perfect—go!"
• "Wait an hour—it will be better"
• "Skip outside—go to treadmill"
• "Today's not the day—rest"

Good decisions require good information.
