What’s my sea level? Discover your oceanic altitude now!

Have you ever wondered about your sea level? Sea level is the average height of the ocean’s surface between high and low tide. The sea level varies in different parts of the world depending on various factors. It’s important to know your sea level as it can affect coastal communities, climate change, and oceanic ecosystems. In this article, we will explore everything you need to know about your sea level and how to discover it.

Factors affecting sea level

There are various factors that affect sea level. These include:

  • Thermal expansion of seawater
  • Melting of glaciers and ice sheets
  • Ocean currents
  • Land sinking or rising
  • Human activities such as oil extraction and coastal developments

These factors can contribute to both rising and falling sea levels. Understanding these factors can help us predict the impact of climate change on coastlines and oceanic ecosystems.

How is sea level measured?

Sea level is measured using tide gauges and satellite altimeters. Tide gauges are installed along the coastlines to measure water levels relative to a fixed point. The measurements taken by tide gauges are used to calculate the sea level change over time. Satellite altimeters, on the other hand, measure the height of the ocean surface from space. They can provide a global view of sea level changes and help us monitor large-scale patterns and trends.

Why is it important to know your sea level?

Knowing your sea level can help you understand the potential risks of living in a coastal community. Rising sea levels due to climate change can cause coastal flooding and erosion, which can impact water supply, infrastructure, and habitats. Accurate knowledge of sea level changes can help us develop strategies to protect these vulnerable communities and ecosystems.

How to find out your sea level

If you want to find out your sea level, you can check online databases such as NOAA’s Center for Operational Oceanographic Products and Services (CO-OPS), which provides real-time and historical data on sea level in the United States. You can also use Google Earth to check your sea level at any location around the world.

Another way to find out your sea level is to use a tide gauge. You can purchase a tide gauge from online stores or rent one from local providers. The tide gauge will measure the water level relative to a fixed benchmark and give you an accurate reading of your sea level.

How to interpret your sea level

Interpreting your sea level readings can be complicated, as it depends on various factors such as tides, currents, and weather patterns. You may need the help of a professional to understand the data and its implications. However, you can use online tools such as CO-OPS’s Sea Level Trends to get an idea of the long-term sea level changes in your area.


Sea level is a critical factor in understanding the impact of climate change and coastal development. Knowing your sea level can help you develop strategies to protect your community and the oceanic ecosystem. By using online databases, Google Earth, or a tide gauge, you can discover your sea level and take the necessary steps to mitigate the potential risks.
